PTT4U is a state-of-the-art network radio service.
Relying on the GSM signal, our radios will be able to talk to each other without any range restriction. Each radio works with a SIM card (not included) and uses GSM/3G/4G and some models even work with WiFi signal. This means you don’t need to spend a fortune on expensive radio infra-structures, repeaters, antennas or leasing sites. All the network infra-structure is provided by the GSM carrier.
«All of my units are working very well. I have crews scattered all over several states in the US and we are communicating in a superb manner. I had men at 700 ft. on a broadcast television tower talking to the men on the ground, 200 miles from my locations, and I was able to listen in to every word. PTT4U will be a game changer for me.»
Bruce Holsted, Holsted Operations
Private and group calls are available. Your team members can be in different countries and still within reach. Each user can check each other’s location (based on their profile), send messages and SOS alerts.
All you need to do, is to purchase our network radios, depending on your needs, insert your preferred carrier SIM card on the radios (a monthly data plan of 500MB will be enough) and subscribe the yearly PTT4U service. You will need one yearly subscription for each radio. And that’s it! No more headaches.
Our PTT4U app comes pre-installed on all our android radios.
You can also connect PTT4U to an existing conventional radio infra-structure, with our crosslink solution.
