Push to Talk Over Cellular (PoC) Apps

Taylor Thomas Oct 07, 2019

Push to talk over cellular (PoC) turns any cell phone into a two-way radio providing a new and enhanced way to communicate. These PoC apps give companies or individuals the opportunity to talk wherever you are in the country. These apps are available for anyone with a cell phone and can be downloaded in the app store and google play. 

All apps have a free option, mainly used by individuals communicating with friends and a subscription based option for companies needing to communicate with their employees. 

PoC apps have the ability to record conversations and can be played back at a later time, if needed. The talk groups are a good option to have for your employees because it puts everyone in a single network so you can easily find whomever you need. This limits time with a tradition cell phone and eliminates unlocking the cell phone, finding the contact in your phone and waiting for an answer. PoC apps allow you to instantly connect with the team and get information in real time. 

Push to talk is a better option than a regular GMRS or FRS radio. With push to talk, you are able to talk to anyone no matter where they are. With walkie talkies, you normally have a small range available to talk. This can leave a gap in communication between employees across different site locations. Also, start up costs for these systems can get expensive with also paying for maintenance and care. 

These apps are an improvement of the traditional walkie-talkie and the ability to instantly connect with your team. We will review the different pricing and features of popular push to talk apps including,  

  • Zello
