In this video, I show how to program each of the keys of the Inrico TM-7 mobile transceiver. You just need to use a special app that will map the keys with the functions you want.
Cellphone operators compatibility
All our network radios work with GSM operators. In the USA, they will only work with AT&T (3G and 4G) and T-Mobile (3G). Note that AT&T will buy any contract you may have with other operators, so you can easily change carrier. The radios will also work accessing any WiFi hotspot.
