Differences between BG95-M3 versions

Hello,
we are trying to figure out the difference between BG95-M3 modules marked Q1-A8383
and Q1-A4448.
We have troubles connecting A4448 onto a Vodafone UK network, while A8383 works just fine. We tried to reflash the modules with matching FW version, but no luck.

Thanks for any help.

Hi @wwc

Could you please help do AT+QGMR on those 2 types module?

Q1-A4448
BG95M3LAR02A03_01.006.01.006
IMEI: 867730054743848

Q1-A8232
BG95M3LAR02A03_01.014.01.014
IMEI: 862406072387380

Tried to upgrade the older item to BG95M3LAR02A03_01.014.01.014 version, but it did not help.

Thats we need modem log to check why cant register to VDF UK network.

Which AT commands do you need the output from?

Please help check AT+QENG=“servingcell” , AT+CGDCONT? when reproduced issue.
