Can I Bind a Bound SIM Card to Another Device? How Can I Rebind It?

GSL enables the device-SIM binding function for IoT SIM cards. When a SIM card is inserted into device A for the first time and activated successfully, the card is automatically bound to device A. If this card is then inserted into device B, the card will be suspended due to device-SIM separation. (Note: China Telecom SIM card will be disconnected from the network but its status is still In use.) You need to apply for device-SIM rebinding to resume the card. The following describes the solutions to the device-SIM separation problem for different carriers:

• China Mobile: The SIM card status displayed on the GSL console is Suspended (due to violation). In the navigation pane, choose SIM Cards > Card List. In the Operation column of the target card, click More, select Rebind Device, and select Ordinary Device-SIM Rebinding to unbind the card. The card will be unbound within three working days and restored to the In use status.
• China Telecom: The SIM card status displayed on the GSL console is In use. In the navigation pane, choose SIM Cards > Card List. In the Operation column of the target card, click More, select Rebind Device, and select Ordinary Device-SIM Rebinding to bind the card to the IMEI of the new device (by default). Restart the device 5 minutes after the operation is complete. A card can be unbound at most twice in each calendar month.
• China Unicom: The SIM card status displayed on the GSL console is Suspended (due to violation). Submit a request and the request will be processed within one to three working days.
