Prepaid Sim card for GPS tracking device
I purchased a prepaid sim card to use in a GPS tracking device for my dog. The device has no IMEI number that I can find. Are AT&T prepaid SIM cards compatible these devices. They are considered wearable devices because they are also used for small children, the elderly and young drivers. This is a 4G device. The device requires a telephone number for data, but I am at a loss regarding activating my SIM card for this device.
