| ==Country Blocking Service==
| | T-Mobile is a telecommunications provider that delivers wireless connectivity services designed to support a wide range of connected devices and business applications. Using its mobile network, the company enables reliable data transmission, device management, and scalable connectivity across various operations. Its offerings include network access, flexible service plans, and tools for monitoring usage and performance. T-Mobile continues to invest in network coverage and 5G technology to support evolving connectivity needs to help organizations maintain efficient, secure and adaptable communication across their devices. |
| Device is blocked when it connects to an operator with restricted '''Mobile Country Code (MCC)''' it saves blocking timestamp (current timestamp + 28 days) and starts the counter. The counter tracks the cumulative number of days the device spends connected to an operator with restricted MCC.
| |
|
| |
|
| If the device reaches '''28 cumulative days''' of connection to to an operator with restricted '''MCC''', it will be '''automatically blocked'''.
| | ==Description== |
| | T-Mobile device certification is a formal evaluation process conducted to ensure that cellular devices comply with established network requirements. In order for devices to operate succesfuly on the T-Mobile network, a successful completion of this certification process, and manufacturers, including hardware vendors, OEMs, and ODMs, is required to obtain product approval prior to deployment. |

| ===Resetting the Counter=== | | ==External links== |
|
| |
|
| To reset the counter and timestamp, the device must connect to a non-restricted '''MCC''' continuously for '''7 uninterrupted days'''.
| | <ul> |
| If the device disconnects from operator with a '''non-restricted MCC''' or connects to operator with a restricted MCC during this 7-day reset period, the reset process fails, and the 28-day counter continues accumulating.

|
| ===Unblocking Conditions===
| | [[Category:FTM880 Certification & Approvals]] |
| | |
| In order for device to be unblocked it must maintain a continuous connection to operators with non-restricted '''MCCs for a full 7 days'''. Additionally, the device must have an active time synchronization and an inserted SIM card. If the device connects to a restricted operator MCC during this period, the unblocking counter resets.

| ===Blocked Actions===
| |
| | |
| While device is in a blocked state the following services are restricted:
