Problems with cellular backup, both with Verizon and AT&T

@davey_d​ I had this question too early on with SS3 and "disconnected" was a term that I suggested be changed in the firmware to "Ready to Connect".  End user(customer) review was always required at my company prior to releasing. Amazing what a different set of eyes find after the "propeller heads" (stated very respectfully btw) think they are done with a project.

@davey_d​ Thank you for answering my questions.  The information you provided is helpful.  I did relocate my base station, and so far, have not noticed the "no link to dispatcher" message.  Verizon in my area lately has been completely unreliable, even with good signal strength.  The network is just too darn congested during the day making data literally unusable.  The new module and AT&T SIM that SS sent me seems to have resolved the congestion issue for the most part.  At times, alerts are still a bit delayed, but it's much better than with Verizon.

Your comment that if Verizon and AT&T don't provide adequate coverage, then T-Mobile won't either, may be true as a generality across the U.S..  However, I know for a fact that in my specific location, T-Mobile provides the fastest, least congested speeds, especially upload, and strongest signal.  The tower is literally less than 1/4 mile away.  It would be great if SS made T-Mobile an option again at some point.  That would allow me, and I'm assuming other SS customers, more/better base station placement options in the home, as well as a better chance of prompt alerts every time in certain situations.

Thanks, again!
