409PTT is the most advanced network radio service.

By relying on GSM signals, our radios can talk to each other without any restrictions. Each radio is equipped with a SIM card (not included), using GSM / 3G / 4G, and some models can even use WiFi signals. This means you don't have to invest a lot of money on expensive wireless infrastructure, repeaters, antennas or rental sites. All network infrastructure is provided by the GSM operator.

All of my departments work very well. We have staff all over the world and we are communicating in a great way. I am on the 500-foot high radio and television tower, talking to the workers on the ground who are 200 km away from me. I can hear every word. 409PTT will be my communication changer.
