M2M Communicator - right now the best

[Leo]

In my opinion right now the best on the market
I only work with the M2M fire alarm device - MN02-LTE-M
The device has three carriers built in
can auto switch carriers or you can email/call M2M to switch
internet compatible
nice phone app
nice web/computer app
respond to emails quick
answer the phone quick
and it is SMALL, can fit into most fire panel cabinets

others:
telguard is trash
starlink is good but only good next to M2M
AlarmNet - Why? have you looked inside the can, great job
