I am having issues with the SIM card not initialising / responding, LTE logs sent:ATE0 with no response from the Modem, with no SIM inserted it logs 'normal' modem AT chatter
I have tried 4 different SIM cards
My Old O2 one and a 1NCE one both work
2 newer O2 data cards, one a year old and one brand new DON'T work.
Both the newer cards are 5G 'ready' / enabled (will work on 5G in a 5G device), the older cards are probably NOT 5G ready.
so is it possible that the 5G enablement is hanging the modem?
This is on a unit with factory default config (eg so no LTE bands enabled, but I tried enabling one and it made no difference...)
Perhaps you upgraded to one of the very recent routeros versions that accidently removes the lte firmware. (eg. 7.23.6, 7.24.3), there is a newer fixed version.
See link below (includes information on how to restore firmware) :
Ive already seen those posts. I have tried with Latest in Stable, LTS and dev branches and the factory default version originally installed... I have opened a support case ...
