GSM Radio

The GSM Radios allow long-distance, even nationwide, unlimited range walkie-talkie operation, anywhere that there is mobile phone network coverage.

Unlike normal walkie-talkies which transmit directly from one radio to another directly within a short range or couple miles, these Gsm radios communicate long distance by sending digitized voice data via the mobile phone data network.

Radios have a display screen for receiving text messages. It also has GPS functionality so that the controller knows where each radio user is located.

Each radio requires a SIM card like a mobile phone, with mobile data.

The radios do not actually make mobile phone calls when you use them they send your voice as mobile data.
