How to select LTE Band 71 and Band 66

IoT Modules MC/EM Series
1

For band 66 and band 71 in LTE, how can I set it so that it’s not band 2 or band 7 given that they have the same bitmasks/hex, respectively? I am currently using this command: AT!GBAND=0000000000000000,0000000000000040 to set band 7 but I want to set to band 71.
Likewise AT!GBAND=0000000000000000,0000000000000002 gives me band 2 when I want to set to band 66

2

Have you tried at!band command?

Here is an example

3

Even with the at!band command, I don’t know a way to specify LTE band 66 or LTE band 71 since they have the same bit masks as band 2 and band 7. Is there some way?

4

they should not be on same bit masks:

I get it now. However, I’m trying to add this new band profile to set band 66 and 71, but it returns an error:
AT!BAND=14,1,"Test71",1,0000000000000000,0000000000000042.

(I did AT!ENTERCND="A710" before.)

6

what are the return of the followings?
