Looks like an interesting radio… I wonder if it would work on a Cruise Ship? I go for a Cruise every year, and keeping in touch with friends in the Ship is difficult at times, most other typical radios have a limited range due to all the steel interference.
Hi,if you want to use this poc radio, you need to make sure the place you use with the network, wifi or 2G/3G/4G. Because this radio should insert the sim card, and will use the cellular network.
If it is Android based, needs to be upto version of Android in order to run Zello, Echolink, Droidstar, Teamspeak, etc.
