Yes, you can lock your SIM to the IMEI of a device. The IMEI (International Mobile Equipment Identity) is an identifier of the cellular modem of your device. You can enable the device lock from the user interface for each SIM.
Once the lock is enabled:
- The user interface device lock for that specific SIM will show as “Waiting”
- The IMEI will be captured in the next connection made by the device.
- The captured IMEI will be bound to the SIM, so any further connection using a different IMEI will be rejected
- The IMEI will be shown in the user interface.
Note:
- The locking mechanism relies on the IMEI being sent when the device tries to connect to the cellular network. Sometimes it is not sent, and if the lock is enabled and the IMEI has already been captured the connection would also be rejected, even if the connection is from the right device
- The IMEI identifies the cellular modem, not the device. A device can have more than one cellular modem. If a device has more than 1 SIM slot and all SIMs can be active at the same time then it has multiple cellular modems. In this scenario, the device won’t be able to connect when a SIM that is locked is moved to another SIM slot.
