1) This guy is a spammer, blasting unsolicited advertising to any
email address with a ham call. I have already received his
advertising at 5 of my email accounts that have some variation of my
callsign in their addresses.<br>
<br>
2) This is NOT ham radio - at least in the sense of a RADIO
operating in a ham band. It's basically a GSM cellphone with
push-to-talk capability. ("POC" in the description refers to
"Push-to-talk Over Cellular" similar to the old Nextel
"walkie-talkie phones". It can push posits into the APRS-IS (not
over ham RF) using an app, like any Android smartphone. [The GSM
protocol for cellular voice is only used by ATT and T-Mobile in the
US.] <br>
<br>
It also appears to have VoIP (Voice over IP) over cellular data, and
VoLTE (Voice over 4G/LTE) capabilities, that can connect to
"International Radio Network"; one of the many Internet-based
linking services. This kinda allows you to play ham radio while
burning up expensive cellular data quotas. <br>
