I am having an intermittent modem connectivity problem on both boards I purchased from Telstra. They have not been modified in any way, however, they intermittently connect to the network. Whenever they fail to connect, both do not connect. When then work they both work. I have tried solutions presented by the team here https://dev.telstra.com/content/arduino-mkr-nb-1500-does-not-connect. Is this a network problem or it is a device problem?
When I try modem test solution I get the following
19:49:00.087 -> Starting modem test...ERROR, no modem answer.
19:49:10.381 -> Checking IMEI...Error: Could not get IMEI
