Hello,
i got a Nbsn95 with the BC95-GV Module.
The problem ist the quectel modul won’t connect (Signal Strength 99 all the time.)
I tried so set APN via:
AT+CGDCONT=0,“IPV4V6”,“lpwa.vodafone.com”
Returned Ok but didnt work
And i tried so set band to 8 or 20 but after restart the band setting is changed to 1,3,5,8,20
If i try to deactivate autoconnect (AT+NCONFIG=AUTOCONNECT,FALSE)
but then i got message: Failed to read IMSI number.
Can anyone help me there ?
Thank you!

Any idea’s on how to diagnose this issue?
This message indicates that the registration network has been rejected. Please double check whether the APN or SIM card status is normal
Thankyou for your response.
2x Sim carriers says it should work.
Is there a way to further troubleshoot the network registration?
Just following up for anyone else who stumbles on this problem.
Turns out both carriers sent me CAT-M1 SIMS instead of NB-IOT. Hence, unable to connect due to incompatibility.
Have you solved your current problem？
