We have device with HL7688 and it work before with one IMSI.
Now cell provider introduced “super” SIM that has multiple IMSI but it is not able to switch to second one.
After “AT+COPS=0” I am constantly receiving “+CME ERROR:111” and some times “+CME ERROR:112”
The same issue with HL8548.
Is there the setting that I need to activate to get it working?
My second issue that HL7688 does allow SIM OTA update but HL8548 does.
I tried to allow SIM toolkit but did not help.
Thanks a lot,
