switch cell provider to telus?

I wanna switch my phone provider from bell to telus, but still wanna keep my cell phone (its a nokia 6275i).
Just wondering if i can be done?
Will it still be able to work with Telus?

Non TELUS / Unlocked Phones.
Do you have an unlocked digital phone that is not from TELUS Mobility? Do you want to somehow activate that phone with TELUS Mobility?

IT IS NOT POSSIBLE!

TELUS Mobility will NOT allow for the addition of any foreign (non-Telus) ESN regardless if the phone is unlocked or not! In short, you CAN NOT use non-Telus phones on TELUS Mobility's network. Please do NOT ask how it can be done because it can't.
