Can anyone tell me what AT! command would tell me what Bands my Sierra modem is detecting? Not which bands it's capable of, but which bands are available/ detectable from my tower. Thanks!
In order to find out all the usable bands in your particular area, you could lock the modem to each band one by one, do an AT!GSTATUS? status after each new lock, and look at the RSSI/RSRP signal.
If it's around -100db AND you can access the internet in a browser, then write it down as one of the usable bands.
These are all the possible bands you can try for each model:
B1, B2, B3, B4, B5, B7, B12, B13, B17, B20, B25, B26, B29, B30, B41
B1, B2, B3, B4, B5, B7, B8, B9, B12, B13, B14, B18, B19, B20, B26, B29, B30, B32, B41, B42, B43, B46, B48, B66
B1, B2, B3, B4, B5, B7, B8, B9, B12, B13, B18, B19, B20, B26, B28, B29, B30, B32, B41, B42, B43, B46, B48, B66
If you don't want to try all bands, then at least try these carrier specific ones:
"*" = main bands
ATT = *2, 4, 5, 12, 14, 17, 29, 30, 46, 66
TMO = 2, *4, 5, 12, 46, 66, 71
VZW = 2, 4, 5, *13, 66
SPR = *25, 26, 41
