Handling Unauthorized IMEIs and SIM Card Authorization

Please allow up to 5 minutes before SIM cards get disabled due to unauthorized IMEIs. Once an unauthorized IMEI is recognized an email is dispatched to your account to let you know.

If no authorized IMEIs are added to SIM cards, all devices will be considered authorized. This is the default configuration for SIM cards.
