PTT4U is a state-of-the-art network radio service. It uses the RealPTT network and can be used with any RealPTT compliant radio.
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.
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.
A complete desktop Dispatch Center is also available.
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.
