Customers may request a seasonal suspend for up to 90 days per suspend period. Limited to 2 seasonal suspensions per rolling 12-month period.

While a line is suspended, you're still responsible for paying your bill and if applicable, your monthly device payment and device protection charges.

• During the seasonal suspension, the full monthly recurring charges will be billed. However, for the T-Mobile Internet AWAY™ plan, the monthly recurring charge (MRC) is $10.
• AutoPay discount will be applied while on suspended when an eligible payment method is used.
• Suspending and restoring your lines is available through T-Life app and myT-Mobile.com.

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 logging back into your T-Mobile.com account.

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 T-Mobile.com or T-Life and select the device, then select "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.
