The phone watch ONLY supports 2G GSM: 850/900/1800/1900, before buying, please double-check with your Carrier if they are still supporting 2G. For US users, we recommend Speedtalk SIM by T-mobile, with $5 plan. As far as we know, Sprint and Verizon not supported, and AT&T has shut down 2G GSM networks. For other countries outside of USA, please double check with your local 2G GSM service suppliers.
