The open directory of Push-to-talk over Cellular devices

What is a PoC radio? Push-to-talk over cellular explained

A PoC radio talks over a carrier's SIM and 4G network instead of its own antennas. How it works, what you need to use it, where it falls short and how to check type approval.

PoC radio cost: device, platform subscription and data

A PoC radio costs three things, the device, the platform and the SIM. Published prices, how much data it uses and what is behind the "no monthly fee" and "lifetime" offers.

PoC radio vs DMR, analog radio and PTT apps

PoC radios, DMR radios, analog radios and push-to-talk apps solve different problems. Compare range, licensing, cost and what works without a network, and when a hybrid radio makes sense.
