Problems with cellular backup, both with Verizon and AT&T
I've been testing the cellular backup on my new SS system, so I have it disconnected from Wi-Fi. I've been having problems with delayed or missing push notifications and sms alerts (sometimes, not always). I've also had "device connection problem" when trying to arm/disarm the system from the app, again sometimes, not always. At times, the base station would show "no link to dispatcher" warning message, but the other issues mentioned occurred even when the base station showed no such warning. This was happening with the original Verizon SIM card, so I called SS and they sent me a replacement cellular module and AT&T SIM. Now the same things are happening with AT&T. Base station showed signal strength on both Verizon and AT&T at about -75 db, which should be sufficient.
My question is what do all the different cell statuses (init, connected, disconnected) in the diagnostics menu, mean? With Wi-Fi removed from the base station, should the cell status always show "connected" when things are working properly? Sometimes, the cell status shows "disconnected" even though I'm receiving timely push and SMS alerts. Also, I sometimes see cell status revert to "init." Why would it keep reverting to "init" status?
What gives? Is a T-Mobile SIM card available, as that has the strongest signal and fastest speeds at my location?
