I have a blackberry pearl but when I insert my sim it says invalid sim.Its a Rogers Blackerry it recognisies the network that the sim is on.But it says invalid sim is it that i need to unlock it.
Re: PearL Questions
Both the BlackBerry and the SIM need to work with the same network. Otherwise you need to unlock the BlackBerry.
For example, if the BlackBerry is Rogers and the SIM is set up for AT&T, you'll get that message and have to get the BlackBerry unlocked for it to work with that SIM.
Once unlocked, that BlackBerry will work on any GSM network like T-Mobile, Rogers, AT&T.
