but you can't really get CB radio frequencies, you need WiFi right? ... or does there exist some kind of hardware "adapter" to send and receive radio frequencies?
If it is cellular signal is what you're referring to, the answer is Yes and No.. Yes if there is wifi connection on the area where you plan to use this and NO if you are referring to cellular signal and you are planning to use data from your mobile network.
May way naman para ma-connect pero need mo pa ng isa pang radio din at modified mobile phone headset, kasi di mo malalagyan or ma-programan ng radio frequency yung software ng Zello.
You mean bro na kahit pareho kayong walang load sa cp pwd kayo mga uusap kung smartphone mo ay naka two radio app?kung halimbawa yung kausap mo ay hindi naka two way app makontak mo ba cya?
As long connected ka sa internet like wifi, kahit walang sim yang phone mo basta need ng app ng internet connection to work and need din na may naka-install na same app yung tatawagan mo at internet connection, data or wifi para makapag-communicate.
SIno ang nag-create ng group?, baka kasi may password yung group na gusto nyong mag-connect. Usually hanapin mo lang ang name ng group click mo yung join or may mag-send sa'yo ng request to join then accept mo lang.
