Original equipment manufacturers must complete a few steps prior to starting our IoT device network certification process. Use the list below as a guide for the items that you will need to complete this process. Click the "Get started" button once you are ready to begin. Get started ## OEM prerequisites for T-Mobile Lab entry. ## To begin our IoT device network certification process, original equipment manufacturers must meet several prerequisites. Here’s a brief overview of the steps you’ll need to take before you start. ## Complete your PTCRB certification. Show compliance with PCS Type Certification Review Board requirements. ## Submit OEM-performed functional test results. Your results will be reviewed and analyzed by T-Mobile. ## Meet T-Mobile end-device criteria. Your test results meet or exceed T-Mobile RF OTA (TRP/TIS) performance criteria. T-Mobile RF requirements can be found [here](https://www.t-mobile.com/content/dam/digx/tfb/us/en/non-dynamic-media/pdf/non_stock_OTA_TFB_v1.pdf). ## Submit compliance documentation. Submit device compliance documentation into the Device Center for Engineering (DICE) tool for review and acceptance by T-Mobile. ## Support IPv4/v6 dual stack or IPv6. If your device only supports IPv4 currently, you must commit to a timeframe to have your device support IPv6 and get T-Mobile approval for a Maintenance Release. ## Enter the OEM TAC into DICE via a TAC Data Card If you use the same TAC as the Module, check “Device Uses Module TAC.”​ Otherwise, select +Add New and enter the TAC. ## Ship us your lab samples. Lab samples must arrive at least 48 hours before their lab entry time and provide tracking details. ## 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. ## OEM prerequisites for T-Mobile Lab entry.
