First off, you (and the person you are trying to walkie walkie) must stayed connected to 4G LTE 100% of the time. If you lose your 4LTE signal for even 1 second, then VerizonPushtoTalkPlus LOSES IT'S CONNECTION and not only can you not use it and nobody can reach you now-- but you must go back to a 4LTE area, re-open VerizonPushtoTalkPlus , and wait for it to "reconnect". I had it for 1 week and had more "user is out of range" more times than it actually works!! It's because Verizon network often drops down to 3G way too often (or even down to 1x if your rural or in a building).
The ONLY way for Verizon to fix VerizonPushtoTalkPlus/push to talk: Instead of the push to talk disconnecting and not working anymore if you lose a LTE signal, it instead should allow you to still talk on their 3G and 1x network. WHY NOT!?! Right now people with older phones can use "1x legacy" and can push to talk to us users on 4GLTE/Enhanced push to talk. So Verizon can easily just allow us to keep using our walkie talkie if we have 3G or 1x, instead of just becoming a useless brick and not working if you lose 4G LTE.
