Country Blocking Service

Behavior Description

Resetting the Counter

To reset the counter and timestamp, the device must connect to a non-restricted MCC continuously for 7 uninterrupted days. 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

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.
