No, you can either choose Microsoft 365 or Netflix on Us when you activate qualifying voice lines. If you are already receiving credit for Netflix, you will need to remove your benefit prior to adding on Microsoft 365 on Us.  Talk to one of our experts about which option is best for you.

Microsoft 365 on Us provides new Microsoft user licenses that you can assign to any member of your business – even employees without T-Mobile voice service. Unfortunately, the new user licenses cannot be part of the existing account you may have already set up through Microsoft or another reseller. This means the value cannot be credited toward your existing account and the Microsoft on Us user licenses cannot be combined into your existing account.


Alternatively, you can ‘switch’ a paid user license by discontinuing the paid version and reassigning that user to your Microsoft 365 on Us license. For assistance with assigning user licenses, please call 1-888-834-8572.


If you would like to consolidate your Microsoft 365 account in one place and on one bill, you can purchase all of your Microsoft 365 user licenses from T-Mobile. To do so, you would cancel your current Microsoft 365 account then take advantage of the Microsoft 365 on Us user licenses plus purchase additional user licenses you need from T-Mobile.

Yes, to upgrade your user license from Business Basic to Business Standard please call 1-888-834-8572. Upgrades from an ‘On Us’ license will only be charged the difference between the Business Basic and Business Standard ($9/month). Qualifying plan required; contact us to activate. One subscription per line, up to 2 lines per account.


Full terms: Activation requires access to Marketplace, a T-Mobile service providing access to Ingram Micro Inc.'s online business-to-business platform for purchasing third-party products and services. Platform and subscription use subject to applicable third-party licenses, terms, and conditions, including the Microsoft Customer Agreement at www.microsoft.com/licensing/docs/customeragreement and Marketplace terms and conditions at https://us.cloud.im/legal/. May not be combined with Netflix On Us, Family Allowances, or content-blocking features; adding these features will result in immediate cancelation of Marketplace subscriptions without further notice. Between $9.04 and $25.98 /mo. value, depending on plan and line count. Value not redeemable or refundable for cash or credit and may not be creditable towards other products. Must remain active and in good standing or licenses terminate and data becomes inaccessible. May take 1-2 bill cycles. Like all plans, features may change or be discontinued at any time; see T-Mobile Terms and Conditions at T-Mobile.com for details.
