One of our RUT240 is facing a new strange issue.
It randomly disconnects for 3-5 hours approximately once every 48 hours. Happened 2 times already in the past 4 days.
Seems due to sim card but I would like to be sure and prevent it from happening again.
I can send troubleshooting file in PM. Here's an extract.
Mon May 16 13:04:37 2022 daemon.info unhandler: modem_init[1-1]: send to gsmd 'AT+CPIN?'
Mon May 16 13:04:37 2022 daemon.info unhandler: modem_init[1-1]: get from gsmd '+CME ERROR: SIM failure
In the attached logs of the events, we see that even a pre-scheduled reboot did not fix the issue. After 3 min we get a "WAN (mob1s1a1) is down, no more backups to switch"
Thanks for the support !
