My BC35-G doesn't support Band 28

Hi All,

Coming from the BC95-G I have started playing around with some of the other variants available. We decided to end up on the BC35-G and everything was looking good. Recently we switched cell provider and they required us to use Band 28. Looking through the datasheet everything looked ok. Though when interacting with the modem itself, it only shows 3,5,8 bands available.

Is it that I may have a dud? Or simply that the BC35-G doesn’t actually support this band at all?

Some extracts from my modem:

at+cfun?
+CFUN:0

OK

at+nband?
+NBAND:5,8,3

OK

at+nband=?
+NBAND:(3,5,8)

OK

at+nband=28
