A:Answer Yes, it takes a SIM card, but I can't tell if i the device is locked or whether you can use a different SIM card. The card slot is located under the battery. It is a larger SIM, so if you have an iPhone or device with a nanoSIM, you will need an adapter.
Note the range is a bit limited, so if you were planning to use this over a large area, it might not work well. After about 20-30 feet you lose the signal.
