You can suspend a line twice in a 12-month period. Each suspension can last up to 90 days.

While a line is suspended, you're still responsible for paying your bill and if applicable, your monthly device payment and device protection charges. Suspending a line may change your monthly plan cost--see information for your specific account type below.

Accounts with individual lines

• For accounts with one line on an individual rate plan, a suspended line will be billed $10 per bill cycl instead of the line's monthly plan cost.
• If an account has multiple individual-line rate plans, the account will be billed $10 per bill cycle for each suspended line, instead of the line's monthly plan cost. Active individual lines will be billed their regular monthly charge. (For example, if you have an account with three lines on individual T-Mobile Magenta® rate plans and you suspend two of the lines, the two suspended lines will each be billed $10 per month. The third, non-suspended line will be billed its regular monthly charge, including any data add-ons and other features.)

Accounts with multiple lines

• If all lines on a multi-line rate plan are suspended, the account will be billed $10 per bill cycle for each suspended line. (For example, if you suspend all lines on a four-line account, you'll be charged $40
• per bill cycle.)
• When one or more lines on a multi-line plan remain active, the account will be billed the plan's regular monthly charge, including any data add-ons or additional features.
• If an added line that's not included in the multi-line rate plan is suspended, the account will be billed the multi-line plan's regular monthly charge, plus $10 for the suspended added line, instead of that line's normal monthly charge.

Yes, please contact Customer Care for military suspensions.

T-Mobile works with government agencies and other major wireless carriers throughout the world to block stolen devices. When you report a device as lost or stolen, T-Mobile reports the International Mobile Equipment Identity (IMEI) number, a serial number that identifies your wireless device, to an international database. This prevents the device from being used on most carrier networks, including T-Mobile's, even if another SIM card is inserted. If you happen to find the device later, unblocking is fast and easy.

If your device is lost or stolen, suspending your service will help prevent additional charges from unauthorized users. Once you suspend your line, it will be inactive and unavailable for use. If you find your device, you can restore service to the line by returning to My T-Mobile.

Your bill is still due as usual when your phone is lost or stolen, including your monthly plan/service costs as well as any applicable device payments and device protection charges.

If you find your device, log into My T-Mobile or the T-Mobile App and select the device, then click "I found my device." We'll walk you through the process of unblocking the device and restoring your service (if applicable).

If you haven't already reported your device as stolen and suspended the line, please do so immediately. This will block the device and the line from further unauthorized use. If your bill shows charges to your device after the loss, but before you suspended service and reported it stolen, you can dispute those charges. We will investigate your account activity, and you may need to provide further information regarding the theft or loss as part of our investigation. We take all facts and circumstances into consideration as part of our investigation, including reviewing your account to compare the usage during the time that the device was missing until the time when the phone was in your possession. We consider all relevant information, including any documentation you can provide demonstrating that the device wasn't in your possession when the charges were made.
