But for voice and sms, you can swap sims no problem.
So would that mean that I would have to cancel my BIS account with say the Malay service provider everytime I travel so that I can use the new service provider or could I say have the BB registered with the o2 service provider for email and use my Maylay sim for calls when I am in Malaysia but still be able to get my emails on the BB from o2??
