Ahhh okay. That makes more sense. I'll right up a quick crash course for you on this after work and post it here

Firstly, I am soo sorry I forgot to get back with you on this. I've been extremely busy the past few weeks.

Anyway if you still need this information, here is a list of all the band masks that I currently have.

B65     0000000000000000        0000000000000001
B66     0000000000000000        0000000000000002

B72     0000000000000000        0000000000000080

B75     0000000000000000        0000000000000400
B76     0000000000000000        0000000000000800
So you wanted these 3 bands together (B5+B13+B66). You take their bandmasks and add them together. Keep in mind that this is hexadecimal so letters can (and will) get involved at times when added the bandmasks together.

Code: Select all

B5      0000000000000010
B13     0000000000001000
B66     0000000000000000        0000000000000002
Your custom bandmask would look like this when they are all added together. This line of code is ready to send to the Sierra Wireless modem and in your case the EM7565. B5+B13+B66 is a pretty easy one to do.

Code: Select all

at!band=0A,"Custom",0,0000000000001010,0000000000000002
The part where it says "Custom" is going to be the name of the band and you can change this to whatever you like.

When using these commands make sure you change the at!band=** index to the numbers that you are not using ex. at!band=0A

Here are some examples of other carrier's bands and what adding their bandmasks together looks like.

Once again I apologize for the extremely late reply. I hope this helps if you're still needing this.

You would be correct. Mine did not reflect one of the bands cause I believe the EM7565 does not support all of the Sprint bands.
