My girlfriend has a Blackberry Curve on Orange, however since registering to use the T-Mobile network too, her phone keep crashing. I suggested her network search be switched back from automatic to just orange however the problem is still continuing. Does anyone have any more advice or things we coud try? Thanks in advance...

Hi,you can unlock your mobile by unlock codes and you didn't mention about your provider and country..i unlocked my mobile by codes from unlocking4u and my provider is UK orange..you can too try but see to that whether your country and provider is listed..because for some service only codes are available..check with that and if your country's provider is listed then get codes and unlock your blackberry.. if you have any basic mobile models for unlocking then try unlocking4free and get it unlocked by submitting the imei number of your mobile and get codes to unlock your mobile..

Well if you are tied to a particular network all you have to do is to unlock your phone to use it any other GSM network. You can get the unlock code through online. Give your IMEI number & get the unlock code for ur mobile .............You also get through online..........I will suggest the website Unlock-Zone.com which is doing good service .....you can approach this website.

If you go on to the Orange Blackberry website

http://www.blackberry.orange.co.uk/

set up an account for him, you may need to resend service books from this site as well to handset.

Also check he has Blackberry internet bolt on added to his number by orange.

So long as the AT&T is unlocked, yes.
