I've read over Jim Helms guide to band locking but I'm just not understanding. I'm trying to lock band 2 and band 13. According to the guide

at!band=10,"B2",0,0000000000000002
at!band=11,"B4",0,0000000000000008
at!band=12,"B5",0,0000000000000010
at!band=13,"B13",0,0000000000001000
at!band=0E,"VZW (All)",0,000000000000101A

So in my understanding

at!band=10,"B2",0,0000000000000002
at!band=13,"B13",0,0000000000001000
at!band=0E,"VZW (2,13)",0,0000000000001002

Would lock those bands together. Its just returning "error". I've put in the

at!entercnd="A710"

Command to make sure I have privilege. I've even tried just straight copy/pasting the original commands and it still just returns "error". Am I missing something?

Check out the spreadsheet @ https://wirelessjoint.com/viewtopic.php?f=16 ... heet#p2034

You would enter:

1) at!entercnd="A710"
2) AT!BAND=0F,"ATT2,13",0,1002
3) AT!BAND=0F
4) AT!RESET

Note: I am using 0F. That is normally an open slot, you may have to use something else. Issuing AT!BAND=? will show you what slots are in use.

My router sometimes hangs up after a reset, so I also power cycle it about 15 sec after issuing reset command.

I still don't quite understand. But it seems to be working. Thanks!

Be very careful issuing commands if you do not understand what they do / effect. I have wrecked a couple of modems myself and it can be a pain to recover.

Best thing is to use the spreadsheet and only enter provided commands.

Glad it got you going

Below are bands that the modem supports for carrier aggregation. Keyword is "what modem supports". Just because modem supports does not mean carrier does:
