UMTS frequency bands - Wikipedia, the free encyclopedia
It appears that Bell/Rogers/Telus use the same 850 & 1900 UMTS bands.
The dialer command you recommended gives me phone info, battery info, battery history, usage stats.
Under phone info --> 'set preferred network type'... I can choose:
wcdma preferred
gsm only
wcdma only
unknown
Does any of this info help?
Perhaps when I tested the Rogers sim, it was connecting on 2G and not 3G? Otherwise, considering Rogers/Bell use the same frequency, does it rule out the option of changing the settings via debugger/qmat?
