Modem connection is not stable

[roysG]

I get many fails of connection in unexpected times.

This is the result in console:

I do a force restart to esp32 when connection is fail, so it restart the esp32 and try again to connect. Sometimes it works and sometimes it fail continuously.

I am using the latest version of tinyGSM.

Sometimes i touched in the sim7070g to make test of re-connection. Is there any best practice recommended for re-connection of network?

The solution will sound so stupid, but you need to check that your wires is ok in 100% This Is AWSOME Library, Thanks You Guys!
