No matter what command I put in for bands it continues to use whatever band it wants, I've tried factory reseting it.
"AT+QCFG="band",0,10003000000"
OK
Command i use and it connects to band 2 instead

I think you need a ,1 at the end to enforce it immediately, else it takes effect next reboot.

So
"AT+QCFG="band",0,10003000000,1"?

Do you get an OK response after issuing the command?

Idk... I only have an em12-g to play with. Bear in mind that all em-20g are engineering samples as there has never been an actual production model. I think quectel has pretty much abandoned it for the time being.

Your band lock is for Sprint bands 41, 25 and 26. How are you connected to band 2 if your using a Sprint SIM card?
Also the command doesnt have a " at the end

adding a
at the end does make it apply immediately I believe is tehe proper syntax.
AT+QCFG: "band"[,<WCDMA_bandval>,<LTE_bandval>,<TDS_bandval>[,effect]]
TDS_bandval isnt used, default 0

If you've factory reset it make sure you run the command
This makes the settings backup in NVRAM again. (Basically)

I am on a Sprint Sim and connected to T-Mobile band 2 and it is working. I left the APN blank and forced it to band two and it worked. I am not recommending this, but it worked for me. The Sprint bands would give me inconsistent connections with varying d/l and u/l speeds.
