Usually the device ID\IMEI is located on a sticker on the tracker body. Also, most tracker models allow you to find out its IMEI by sending the corresponding SMS command to the tracker.
SMS commands are usually contained in the instructions for the tracker.
As far as we can see, you have already managed to restore IMEI and create a unit with the tracker.
If you have any additional questions, please feel free to contact us again.
