Contact the service provider to run a SIM update.
Make sure the smartphone is running the most recent version of the BlackBerry Device Software.
Contact the service provider to run a SIM update.
Restart the smartphone. The phone number should appear in the Phone application

Huh?
bisleri, that makes no sense whatsoever.

Stevegeddes - was the BlackBerry Unlocked so you could use any carriers SIM card in it? If not, it will only work with the original carrier. It is easy, cheap and safe to have it unlocked.

Unless the BB is not really unlocked any SIM should work.

How do I determine if my BlackBerry is "unlocked"? - BlackBerryFAQ

I have an experienced the same situation when i went to Singapore last year. I tired unlocking my phone by contacting the local GSM service provider but they cant help. Then i heard that i can get the unlock code from the third party online sites. Finally i got my BB 9780 Bold phone unlock code from the site SimpleUnlocking.com and they provided the code within 1 hour and saved more money.
