I recently won a brand new Blackberry (Telus) however, I am currently under contract with Bell.
Is it possible to activate this phone for use with Bell?
Yes,you will be to use it.
But your Blackberry phone is free of Telus network lock.If it's locked means,you will need to unlock it.For unlocking you can approach your service provider or else try to buy an unlocking service from any one of the online unlocking service provider like Unlocking4U.com
