My mate was given a Blackberry Bold 9900 locked to Orange from his girlfriend who had it on contract... He got the phone unlocked n Tmobile, Vodafone n O2 work fine in the phone... But he's on network 3 n when he puts the sim in it says sim card unprovisioned. I'm guessing 3 network sims have to work in 3 network phones? Is this the case can someone confirm? The sim works fine in another 3 phone so sim isn't faulty.
