using my Huawei P30 phone, i can see that tower supports 4G+ with Band 1+3+28 and Band 3+3+1, even doing Band 3+3+1+28. so i tried it on the em12-g.
i have tried using the spreadsheet to my em12-g :
AT+QCFG="band",0,8000005
it works for Band 1+3+28.
however when i try:
AT+QCFG="band",0,9 for Band 3+3+1
it doesnt work. i only get band 1 alone.
I found that default settings for the band is:
AT+QCFG="band",5af0,2000001e0bb1e39df
Does anyone have an idea what to do?
Do you know how to set which band as primary?

How did you get to combine them into 9? To me, that's just B1 + B4. I got 8000004 for B3+B28.roddel007 wrote: Sun Sep 27, 2020 12:59 am however when i try:

Default config will use all the bands possible. You cannot set a band as primary with multiple bands. It's up to the tower to let you get whatever primary band it feels like. If you have the AT commands manual, you could try to find if there is a command for band priority (doesn't guarantee you will use that band as primary, it just scans for that band first) to see if it helps but there is no set band as primary command.
