I have just bought a Blackberry 8520 to use on BT Mobile. I had been told that I should be able to use my BT Mobile sim card on a Blackberry.
However, I have received a text message saying 'Sorry, we are unable to recognise your handset.'
Should I worry? Please help!
Where did you buy it, is it locked to a network?
You might have to manually set up APN's for BT Mobile.
Tnak you very much for your reply.
I bought it from Amazon. I bought it 'sim free' and it's is meant to be unlocked.
I do not understand APN, so am going to look it up on Google.
I've posted elsewhere on this - I have the same issue. BT have to 'resend service books', but apparently can't or won't.
