UScellular and T-Mobile are coming together to deliver a better wireless experience for our customers, and many improvements are already available today: - Stronger network performance: The networks have been integrated, bringing broader coverage, more reliable calling, and faster data speeds. Customers are gaining expanded access to T-Mobile’s nationwide 5G network. - ###### What’s happening now? We’re currently focused on integrating networks to give you the best experience possible.

Plus, with the recent addition of T-Satellite, customers can take advantage of the T-Mobile satellite-to-mobile network ready to help keep your business connected in places no cell tower can reach. As we've been diligently working on the migration to the award-winning T-Monile network, we hope you are enjoying the many improvements already in place. We're excited, because we know your experience will only get better in the months ahead. As we continue bringing the T-Mobile advantages to more customers, some account updates must now be completed under the T-Mobile brand. Your service stays the same today. Also, as we continue to prepare to bring the T-Mobile network experience to more customers, some additional account updates will occur. Some account activities—such as suspensions, upgrades, adding lines, plan changes, and accessory purchases—will no longer be supported on UScellular self-serve portals beginning May 1, 2026 ## Account Migration - ##### I received a message on my phone asking me to accept an eSIM. Why am I receiving this message? Is it spam? No. This message is from T-Mobile for Business and is required to help your device connect to the T-Mobile network. To avoid any interruption in service, be sure to accept the eSIM notification when you receive it. If you dismiss or ignore the message, your device may lose network connectivity. If you accidentally dismiss the notification, you can redownload the eSIM through your device settings or contact T-Mobile Customer Care for assistance. - ##### Do I need to take any action after my account moves to T-Mobile? Some customers may need to take additional steps after their account is moved to T-Mobile. This may include replacing a device, activating a new SIM card, or accepting an eSIM. If any action is required, T-Mobile will contact you with instructions and timelines to ensure your service continues without interruption. - ##### Am I eligible for an AutoPay discount? How do I enroll? Yes. T-Mobile offers AutoPay discounts when you pay using a qualifying payment method, such as a bank account, debit card, or T-Mobile credit card. For most customers, existing AutoPay information will transfer from their UScellular account. If you need to update or enroll in AutoPay, you can do so through Account Hub. - ##### Where can I find my legacy UScellular account history, such as bills or call detail records (CDRs)? For most customers, historical account information, including bills and call detail records, will be available in Account Hub. If you cannot locate the information you need, contact T-Mobile Customer Care for assistance. - ##### How do I find my T-Mobile for Business account executive? Not all business accounts are assigned a dedicated account executive. If your account has an assigned representative, they will contact you directly. If you're unsure whether you have an account executive, contact T-Mobile for Business Customer Care for assistance. - ##### How do I contact T-Mobile for Business Customer Care, and what are the support hours? T-Mobile for Business Customer Care is available to help with account questions, technical support, and service-related needs. You can also access Account Hub 24/7 for self-service account management, billing information, and support resources. - ##### Where can I go to upgrade devices, add lines, or make changes to my plan? You can manage many account changes directly through Account Hub, including adding lines and reviewing available options. If you need additional assistance, contact T-Mobile for Business Customer Care or your T-Mobile sales representative. - ##### I want to add or upgrade my business internet solution. What are my options? T-Mobile offers a variety of business internet solutions designed to meet different business needs. Visit the T-Mobile for Business website to explore available options, or contact your T-Mobile sales representative or Customer Care team for personalized recommendations. - ##### How can I learn more about T-Mobile for Business plans, devices, offers, and solutions? Visit www.t-mobile.com/business website to explore the latest plans, devices, and business solutions. You can also contact your T-Mobile sales representative or T-Mobile for Business Customer Care for guidance on solutions that best fit your business needs. ## Account changes and timing - ##### What is my T-Mobile Account PIN? *Protecting our customers’ information is a top priority, which is why we ask for customers’ 6-digit Account Personal Identification Number ( Account PIN) to authenticate and access your account with T-Mobile Customer Support. You should have received an email from us when your account moved over that included a link to set up your Account Hub online account. If you cannot locate that email or the link has expired, you can also use the 4-digit Account PIN of the Primary Contact on your USCC account and add two 0’s to the end to make an equivalent T-Mobile Account PIN. For example, if your USCC Account PIN was 1234, your T-Mobile Account PIN will be 123400. This will allow you to set up your Account Hub account as well as access your account with T-Mobile Customer Support.* - ##### How does this impact my account? As we enter the next phase of migration, you may notice a few operational updates designed to deliver simplicity and performance. As systems align, you may see updates to plans, products, or support experiences—communicated clearly and implemented with minimal disruption. As part of this transition, we don’t expect your monthly cost to increase or a reduction in your plan benefits - ##### Can I still add a line or change my rate plan with my UScellular account? Starting May 1, some account updates—like adding a line, upgrading a device, or changing your plan—must now be completed under the T-Mobile brand. Once your account has moved to the T-Mobile system, you can upgrade devices and add lines. If you’ve received a notification regarding potential device incompatibility, please contact us so we may assist in preparing your account for migration to the T Mobile network. Our teams will guide you through the options available and help you find what works best for your needs. Contact USCelluar business support at 866-872-4249 (US4BIZ). Any new Business Internet service is offered through T-Mobile. - ##### When will my account move to T-Mobile? Accounts will move in phases, __starting in May 2026__. We’ll notify you when your account is ready to move and guide you through next steps. - ##### If I have an account with T-Mobile and UScellular today, what will happen? Nothing will change right now. Your T-Mobile and UScellular accounts will continue to be managed separately. You won’t see any changes to your current plan, pricing or benefits because of this move. If you choose to combine or make changes to your accounts in the future once your account has moved to T-Mobile systems, we’ll guide you through your options when the time is right. There’s nothing you need to do at this time. - ##### Will my phone number change? For voice devices, your phone number won’t change as part of this move to T-Mobile's system. Depending on the business data solution you’re using, the phone number for data devices might change to support delivering the best T-Mobile network experience with the transition. - ##### Will my account or login change? For now, your account information and login will remain the same. Once your account is moved to T-Mobile systems, you’ll get a notification with further instructions to set up your new login and password. - ##### What happens if I don’t do anything? For most customers, there's nothing you need to do right now. If you’ve received a notification of potential device or SIM incompatibility, please contact us via the method provided in the notification. to help prepare your lines to transition to the T-Mobile network. - ##### What do I have to do to get new T-Mobile products and services?

For new lines of service you can work with your Sales teams, explore product and solutions on the T-Mobile, or call 855-408-0739 for sales requests.

While you don’t need to take action now, you can choose to migrate early. Your UScellular account expert can walk you through the details. Early migration is similar to changing providers today—but with all the benefits of T-Mobile for Business support, rated #1 by J.D. Power Customer Satisfaction with Medium Business Wireless Service. Whether you make the move now or wait, we’re excited for you to experience everything T-Mobile offers. - ##### Will my account tools and support change once I migrate? Until migration, your account tools, and invoices remain the same. After migration, you’ll enjoy: - A new T-Mobile for Business digital portal for account management - Direct billing from T-Mobile - Access to T-Mobile’s full portfolio of business solutions - ##### How will I stay updated? We’ll continue to keep you informed about every step of the way—clearly, simply, and with plenty of time to prepare. What you can count on now: - Your network experience will keep getting stronger. - Our people are ready to make the transition seamless, so you can stay focused on running your business. - ##### Will there be changes to my account and plans? Yes, as a new T-Mobile customer, your account will now be subject to T-Mobile policies, which are different from UScellular policies, including differences in billing and fees for some customers. As part of this transition, we don’t expect your monthly cost to increase or a reduction in your plan benefits - ##### Will late payment fees change after my account moves to T‑Mobile? Yes, after migration, late payment fees will follow T‑Mobile’s policies and calculation methods. A late fee of $10 or a variable percentage allowed under state law is applied to an unpaid past due balance not paid by the due date. Late payment fees are not applicable for government accounts. - ##### Is there a fee if I call customer support to make a payment or set up a payment arrangement? Yes. A $10 payment support fee may apply when a representative assists with a one‑time payment or payment arrangement by phone or in a retail store. - ##### When are automatic (direct debit) payments processed? T‑Mobile typically sends automatic payment requests two days before the bill due date. This timing may be different from how payments were processed previously with UScellular. - ##### What happens if my automatic payment fails? T‑Mobile may automatically attempt to retry certain failed payments when the failure is caused by correctable issues, such as missing information. This is not applicable for lines served through the IoT Platform Control Center - ##### How do I get training on Account Hub? We offer live training via Microsoft Teams for all T-Mobile for Business customers every other Wednesday from 10am-11am Pacific Time. Topics include: Login/Passwords, Account Maintenance, Shopping, Profile Management, and Billing/Statements. Upcoming dates are: 6/17/26, 7/1/26, 7/15/26, 7/29/26, 8/12/26, and 8/26/26. [Use this link](https://teams.microsoft.com/l/meetup-join/19%3ameeting_Y2I2N2M0ZWEtOGNkYy00ZDVkLTg0ZjYtNDRmNWM2ZjJkYTUx%40thread.v2/0?context=%7B%22Tid%22%3A%22be0f980b-dd99-4b19-bd7b-bc71a09b026c%22%2C%22Oid%22%3A%221d5bfa2c-7d5d-411f-a827-507fa382f4b4%22%7D) at 10 AM Pacific Time on any of the above scheduled days to join! ## Billing and Bill Cycles - ##### Will my bill or billing date change? For some businesses, bill due date has already shifted by up to five days starting with your March bill. If that is your case, you have already received a notification. For accounts that were not impacted in March, when your UScellular account moves to T-Mobile’s system you will a new bill due date, which is approximately 20 days after your Bill Cycle. Your Bill Due Date will show in your first bill. For customers that reside in Illinois, please be aware that this new date can be up to 12 days earlier than your current Bill Due Date. - ##### Do I need to update my AutoPay? If your business received a notification about the Fiserv end-of-life, please update your AutoPay settings. If AutoPay is currently enabled on your account, those settings may transfer when your account is migrated to T Mobile’s billing system; however, such transfer is not guaranteed. Following completion of the migration, customers are responsible for verifying whether AutoPay has successfully transitioned. If AutoPay did not transfer, you can view and edit your autopay settings via Account Hub once you have registered. Otherwise, you can contact T Mobile Support Experts at 800 375 1126 for assistance. Support Experts can provide guidance on reestablishing AutoPay, if desired. Otherwise, no action is needed at this time—your AutoPay will stay the same until migration. After migration, you’ll receive step-by-step instructions to set up your new AutoPay. - ##### Do I need to make any changes to how I receive or pay my bill? No. The way you receive your bill, your current rate plan, and your discounts remain unchanged today. When your account moves to T-Mobile’s system, we’ll notify you if any updates are needed and provide clear instructions ahead of time. Your plan price and benefits will remain the same or better, and there’s nothing you need to do at this time. - ##### What happens if I miss a payment? Before migration, UScellular’s late payment policies will apply. After your account is migrated, T-Mobile’s late payment fees and policies will apply for current business customers - ##### Why don’t I see an Administrative Fee/Administrative Fee credit on my T‑Mobile bill? UScellular billed an Administrative Fee as a separate line item. T‑Mobile T-Mobile approaches that differently and instead applies a combined fee called the __“T‑Mobile Regulatory Programs and Telco Recovery Fee.”__ If you have an Administrative Fee waiver before migration, your lines will receive a monthly credit of $1.62 applied toward the T‑Mobile Regulatory Programs and Telco Recovery Fee. The credit is tied to the original line number and plan at the time of migration (credit will stop if any of the original criteria- number or plan- changes.) New lines added after migration will not receive an Administrative Fee Waiver credit. - ##### Will regulatory fees change after migration? Yes, Regulatory Fees may appear differently. For more information please visit [__Your bill and what's impacting it | T-Mobile Support__](https://www.t-mobile.com/support/account/whats-impacting-your-bill) and refer to the section titled: “__Regulatory Programs & Telco Recovery Fee”.__ If you have a Regulatory Cost Recovery Fee waiver before migration, your lines will receive a monthly credit toward the T‑Mobile Regulatory Programs and Telco Recovery Fee. The credit is tied to the original line number and plan at the time of migration (credit will stop if any of the original criteria- number or plan- changes) New lines added after migration will not receive a Cost Recovery Fee waiver credit. - ##### Why might my bill cycle change before my account moves to T‑Mobile? Some accounts may require a billing cycle adjustment before or after migration so T‑Mobile can maintain pricing and benefits equal to or better than what you have today. If required, the bill cycle change will occur between May 2026 and July 2026 - ##### Will a billing cycle change affect my services or pricing? No, your services, pricing, and benefits will remain the same. - ##### What is a short‑cycle bill? If your bill cycle changes, a short‑cycle bill will be created. This bill is a one‑time bill covering fewer days than a typical billing period. It’s created only to align the cycle before migration and does not represent an extra bill. ## Devices and Account Changes - ##### Will my current phones continue to work? In many cases, yes. Most UScellular devices are compatible with T-Mobile's network. If a device or SIM card update is required, we'll notify you by email, mail, or text message. If you didn’t receive a notification, no action is required. If a device or SIM card update is required, we'll notify you by email, mail, or text message and provide instructions. If you don't receive a notification, no action is required. Once your UScellular account moves to T-Mobile's system, we'll share additional information and support to help ensure the best experience. - ##### I need a new phone; do I need to switch to T-Mobile from UScellular to upgrade? Starting May 1, some account updates—like adding a line, upgrading a device, or changing your plan—must now be completed under the T-Mobile brand. Once your account has moved to the T-Mobile system, you can upgrade devices and add lines. If you’ve received a notification regarding potential device incompatibility, please contact us so we may assist in preparing your account for migration to the T Mobile network. Our teams will guide you through the options available and help you find what works best for your needs. Contact UScelluar business support at 866-872-4249 (US4BIZ). As UScellular is now part of T-Mobile, new internet service is offered through T-Mobile. - ##### Will I need a new SIM or eSIM? Most customers will not need to change their SIM or eSIM. Some customers may require a new SIM card. If you’ve received a notification regarding potential device incompatibility, please contact us so that we may assist in preparing your account for migration to the T Mobile network. Our teams will guide you through the options available and help you find what works best for your needs. Contact UScelluar business support at 866-872-4249 (US4BIZ). - ##### Will T-Mobile Business Internet be offered to UScellular customers? Yes. UScellular customers can now activate T-Mobile Internet services starting at $35 per month with AutoPay, plus taxes and fees, when you have an active UScellular voice line. Reach out to your Sales Associate for additional information. - ##### Will vanity phone numbers continue to be supported? No, T‑Mobile does not support vanity phone numbers, so this feature will be discontinued during the transition. - ##### Why was my suspended line cancelled /resumed? Lines suspended more than 200 days have been cancelled. Cancelled lines can be brought back into an active status but cannot be re-suspended. Suspended lines that have met or exceeded the maximum temporary suspension timeline (30, 60, 90, 120 days etc.) but have not been suspended for more than 200 days have been resumed. - ##### What is changing with Voluntary Suspend? Beginning March 1, 2026 customers have been able to suspend their line(s) for a maximum of 30 days regardless of the suspension code selected. Also, customers can only suspend for one 30-day period. After May 1,2026 customers will not have the option to suspend services as their account is prepared to be moved to T-Mobile’s billing system. - ##### Will I be able to use my seasonal suspend arrangement? Once migration occurs, T-Mobile offers voluntary suspension twice a year for a maximum period of 90 consecutive days for each suspension. During a seasonal suspension, your account must remain current. You can suspend individual lines of an account, while other lines remain active. For more information visit [__Account Suspension__](https://www.t-mobile.com/support/account/account-suspensions). Other suspensions arrangements and offerings will no longer be available after migration. - ##### Why was my account separated into multiple accounts before moving to T-Mobile? To ensure a seamless migration to the T-Mobile systems, some accounts needed to be broken into separate accounts to ensure the products move to the correct T-Mobile platforms. In many cases the lines can be combined back into a single account once all lines are on the T-Mobile. - ##### Why did I receive a notification some of my devices or SIMs need to be updated? To help ensure your service continues working smoothly, there’s an update you need to complete soon. Your account was identified as having devices or SIMs which will no longer fully support the improved network experience. Taking care of this update now will help ensure everything continues working without interruption to your services. ## Promotions and Benefits - ##### What happens with any offers/promotions I was taking advantage of? Any offers or promotions you’re currently receiving will continue as part of your existing UScellular plan. When your account moves to T-Mobile’s system later this year, we’ll make sure your current offers and promotions are honored. If any changes are needed, we’ll notify you ahead of time and clearly explain your options. There’s nothing you need to do right now. ## Privacy and Terms - ##### When will I move to T-Mobile’s Terms & Conditions? As notified earlier this year, beginning April 2026, Small Businesses transitioned to T-Mobile’s Terms & Conditions automatically through continued service use. Customer with 500+ employees please refer to the notification sent to your billing address with the following information - ##### What are the benefits of T-Mobile’s Terms & Conditions? - No early termination fees – flexibility without penalties. - Transparent pricing – simple, straightforward, and free of surprises. - No annual service contracts – stay because you love it, not because you have to. - ##### What about my personal data and privacy? Your data remains protected under the UScellular Privacy Policy for now. You’ll be notified of any changes to the applicable Privacy Policy. As your account moves to T-Mobile’s system later this year, your information will be used only as needed to support the transition and continue providing your services. Your personal data will remain protected and handled in accordance with applicable privacy laws and company privacy policies. - ##### What will happen with your contract Your U.S. Cellular contract was previously assigned to T-Mobile and will be amended, effective 30 days from the date of this letter, to reflect changes within U.S. Cellular’s business. Specifically, the Information Security exhibit, the applicable T-Mobile Services and Product annexes, including without limitation, the TfB Master Account Wireless Services Product Annex, the IoT Services Annex and Third-Party Solutions terms and conditions, as posted to the website currently found at the URL: [https://t-mobile.com/business/terms-and-conditions](https://t-mobile.com/business/terms-and-conditions), as may be updated from time-to-time, are incorporated into Your U.S. Cellular contract and apply to all Services, Products and Third-Party Solutions You purchase from T-Mobile. To the extent there is a conflict between the terms and conditions in Your U.S. Cellular contract and the T-Mobile terms and conditions, the T-Mobile terms and conditions will control. Your continued usage of, or payment for, any Service, Product or Third-Party Solution, 30 days from the date of this letter, will be deemed Your acceptance of the amendment. Any capitalized term not defined in this letter has the meaning set forth in the TfB Terms and Conditions. ## Refunds and Credits - ##### Will return/refund policies change after migration? Yes, refund eligibility and timelines will follow T‑Mobile policies once your account has moved to the T‑Mobile system. For more detail on return policy, visit [__Return Policy__](https://www.t-mobile.com/responsibility/legal/return-policy). - ##### What happens if a refund is pending during migration? In some cases, accounts with pending refunds may be processed before migration to ensure billing accuracy. ## Other Changes - ##### When will I see other changes? Later this year, your account will move to T-Mobile’s systems. At that time: - You’ll receive your invoice directly from T-Mobile. - You might experience a change in bill cycle and fees (aligning with T-Mobile Terms and Conditions) - You’ll keep your current mobile numbers. - You’ll move to a T-Mobile for Business plan that’s the same—or better—than your current plan. We’ll work closely with you to ensure the transition is smooth, seamless, and worry-free. - ##### If I need to contact customer service, which number should I call? You can continue to use the same number you’re used to, such as 800-819-9373 to contact a UScellular representative for assistance, or dial 611 from your UScellular device. Later this year, when your UScellular account moves to T-Mobile’s system, we’ll let you know if anything changes and provide clear instructions on how to contact support. - ##### Can I get back my previous phone number after I decide to change it? If you wish to reclaim a number, T‑Mobile holds previous phone numbers for 30 days. This may be different from previous UScellular policies. - ##### Will AutoPay discounts apply when using a credit card? No, AutoPay discounts typically do not apply when paying with a credit card. ## Promotions - ##### Will I be charged any fees because of this transition? No. You will not be charged any fees as a result of your account moving to T-Mobile. ## Voicemail FAQs - ##### Why is my voicemail experience changing? In connection with UScellular’s transition to the T Mobile network, voicemail services may be migrated to T Mobile’s voicemail platform. This migration is not guaranteed. Customers are advised to regularly save any voicemail messages containing important information. - ##### After I put in my new SIM, how do I check my voicemail? Before SIM conversion: dial your own number, \*86, or long press 1. After SIM conversion: - Long press 1 — best option - Dialing your own number — works, but always asks for PIN - \*86 — no longer works - 123 — connects to your new T‑Mobile voicemail - ##### Why am I being asked to set up voicemail again? You receive a new T‑Mobile voicemail box when your SIM is activated. You’ll set a new PIN and greeting the first time you call voicemail. - ##### I have an iPhone. What happens to Visual Voicemail? You’ll see a “Set Up” button in the Voicemail tab once you switch SIMs. Tap it to set PIN/greeting—unless you already set them by calling in. Previously saved voicemails on your device stay on your phone. - ##### What about my old UScellular voicemails? Can I still listen to them? Yes. Before migration is complete, you can still reach your UScellular voicemail by: - Calling voicemail - Choosing Mailbox Options (4) - Pressing 8 (connects you to your old voicemail box) - ##### When will my old voicemails move over? Migration happens overnight. Your UScellular voicemails and greetings will be moved into your new T‑Mobile voicemail automatically. - ##### What happens to my old greeting? If you set up T‑Mobile voicemail before migration: your T‑Mobile greeting stays active; your UScellular greeting is stored as inactive. If you did not set up voicemail before migration: your UScellular greeting becomes your active greeting, and you can choose to keep it or record a new one. - ##### After migration, how do I check voicemail? Use long press 1 as usual. All your old and new voicemails will be in one T‑Mobile inbox. Key reminders: - Long press 1 to check voicemail - Complete the new voicemail setup once - Temporary Option 8 lets you access old UScellular voicemail (until migration completes) - Old messages and greetings migrate overnight - Everything ends up in one place after migration - ##### Did I lose all my old voice messages when my account moved to T‑Mobile? Voicemail retention during the migration process may vary by customer and is not guaranteed. UScellular and T Mobile do not guarantee that existing voicemail messages will be retained or transferred as part of the account migration. For customers whose voicemail messages were successfully retained during the overnight migration process, previously received UScellular voicemail messages may be available following migration, alongside any new T Mobile voicemail messages. For iPhone users, voicemail messages that were previously downloaded and stored locally on the device will remain stored on the device; however, retention of voicemail messages through the migration process cannot be guaranteed. ## Follow T-Mobile for Business - [LinkedIn](https://www.linkedin.com/showcase/t-mobile-business/?INTNAV=fNav%3ALinkedIn) - [Facebook](https://www.facebook.com/Tmobileforbusiness/) - [X](https://twitter.com/TMobileBusiness/) - [YouTube](https://www.youtube.com/@t-mobileforbusiness) - [English](https://www.t-mobile.com) - [Español](https://www.t-mobile.com) - ### Contact an expert Contact an expert - [Talk to an expert 1-855-977-4135](tel:) - [Email an expert](https://www.t-mobile.com/business/b2b-contact-information) - ### Customer Care Customer Care - [My account log in](https://tfb.t-mobile.com/?INTNAV=fNav%3AMyAccountLogin) - [Call a CARE expert](tel:) - [Online support site](https://www.t-mobile.com/support/business) - ### Plans Plans - [Business Phone plans](https://www.t-mobile.com/business/wireless-business-plans) - [International coverage](https://www.t-mobile.com/business/international-coverage) - [Small Business Internet](https://www.t-mobile.com/business/solutions/business-internet-services/small-business-internet) - [Business Internet](https://www.t-mobile.com/business/solutions/business-internet-services/business-internet) - ### Resources Resources - [Reasons to switch](https://www.t-mobile.com/business/reasons-switch-t-mobile-business) - [DIGITS](https://www.t-mobile.com/business/solutions/digits) - [Merger benefits](https://www.t-mobile.com/business/t-mobile-sprint-merger-benefits) - [Events](https://www.t-mobile.com/business/t-mobile-events-webinars) - ### Segments & Industries Segments & Industries - [Small/Medium businesses](https://www.t-mobile.com/business/small-midsize-business) - [Enterprise](https://www.t-mobile.com/business/enterprise) - [Government](https://www.t-mobile.com/business/government) - [Public safety](https://www.t-mobile.com/business/government/public-safety) - [Education](https://www.t-mobile.com/business/education) - [Libraries](https://www.t-mobile.com/business/industry-solutions/libraries) - ### More from T-Mobile More from T-Mobile - [Wholesale](https://t-mobile.com/wholesale?INTNAV=fNav%3AWholesale) - [Consumer wireless](https://www.t-mobile.com/) - [Become a T-Mobile Partner](https://businesspartners.t-mobile.com/English/program_overview.aspx?INTNAV=fNav%3ABecomeT-MobilePartner) [](https://www.t-mobile.com/) - [About](https://www.t-mobile.com/about-us) - [Investor relations](https://investor.t-mobile.com/investors/default.aspx?INTNAV=fNav%3AInvestorRelations) - [Press](https://www.t-mobile.com/news) - [Careers](https://www.t-mobile.com/careers) - [Deutsche Telekom](https://www.telekom.com/en?INTNAV=fNav%3ADeutscheTelekom) - [Puerto Rico](https://www.t-mobilepr.com/?INTNAV=fNav%3APuertoRico) - [Privacy notice](https://www.t-mobile.com/privacy-center/our-practices/privacy-policy) - [Trust Center](https://security.t-mobile.com/?INTNAV=fNav%3ATrustCenter) - [Privacy Center](https://www.t-mobile.com/privacy-center) - [Consumer information](https://www.t-mobile.com/responsibility/consumer-info) - [Public safety/911](https://www.t-mobile.com/responsibility/consumer-info/safety/9-1-1) - [Terms & conditions](https://www.t-mobile.com/responsibility/legal/terms-and-conditions) - [Terms of use](https://www.t-mobile.com/responsibility/consumer-info/policies/terms-of-use) - [Accessibility](https://www.t-mobile.com/responsibility/consumer-info/accessibility-policy) - [Open Internet](https://www.t-mobile.com/responsibility/consumer-info/policies/internet-service) - [Do Not Sell or Share My Personal Information](https://www.t-mobile.com) - [Licenses & Patents](https://www.t-mobile.com/responsibility/legal/licenses-and-patents) - [Instagram](https://www.instagram.com/tmobile/) - [Facebook](https://www.facebook.com/Tmobileforbusiness/) - [X](https://twitter.com/TMobileBusiness/) - [YouTube](https://www.youtube.com/@t-mobileforbusiness) © 2026 T‑Mobile USA, Inc. ## We’ve been expecting you.
