have you checked if the LTE band is supported in your location?
You can check current band in your module by the followings:
AT!entercnd=“A710”
at!band?
have you checked if the LTE band in specification is supported in your location?
Yes, alredy check. There is it
This is the band plan in Italy with frequency
Have you set to LTE only in at!band?
What is the return of at!gobiimpref? And at!gstatus?
When you force LTE only, the signal RSRP of antenna is very bad…
not sure if this is antenna problem or location problem?
BTW, did you set correct APN in AT+CGDCONT?
From at!gobiimpref, you might need to download a new firmware with generic setting
Ok, I have update firmware, force to LTE only correctly but ever same problem , service not avaible .
Not sure why the signal RSRP of antenna is very bad…
