after blocking bands 1+3+7 with the command:
AT+QCFG=“band”,0,45,1
I would like to be able to restore the starting situation with all the bands chosen automatically by the module. Which command should I use?
I tried with the command:
AT+QCFG=“band”,0,0x7FFFFFFFFFFFFFFF,1
but it doesn’t work (and sorry if the question might be stupid).

You don’t need to add 0x, see your own example.
If it doesn’t work with FFs - check the allowed values for “band” with AT+QCFG=?

a follow up question why this command doesn’t work?

ps: copy/paste your command
Well, then it is probably a firmware bug or limitation.
I think this is it…
thanks for the help
