Whoops, I made a mistake. It mistook the 2730 as another GSM phone speak out sells, I thought you were talking about either the 2720 or 2760. My bad.

The Nokia 2730 does the required UMTS/HSPSA frequencies as well as GSM. Your problem is that your rogers phone is locked, and until you unlock it, it will not work with Bell sims.

The source cc sells a bell 2730 for $50. maybe that is an option.

Rogers has their own towers for the most part. Even when they share a tower, they use their own gear. Rogers and Bell have a partnership with their wimax network though. Telus and Bell share gear and towers. Bell supplies the east. Telus supplies the west.

Ok, I see your problem. Assuming it is not locked, which if it works on Rogers, it probably is not locked, you own a Nokia 2730 that only does the European UMTS/HSPSA frequencies, something like 900 mhz/1800 mhz/2100 mhz. Bell/Telus/Virgin support none of these frequencies. Rogers/FIDO/Speakout do not support these frequencies either, but since these carriers also support the GSM network, you have a working 2g Nokia 2730. Not so with Bell, no GSM, and no working UMTS/HSPSA frequencies make for a useless phone.

Bell/Telus/Virgin only do UMTS/HSPSA at the 850 mhz or 1900 mhz frequency. Getting a European model is usually a very bad idea, because manufacturers have been known to make 2 versions of the same UMTS/HSPSA phone, a European and a North American version. You got the wrong version, sadly.
