I have an unlocked samsung i9000 and whever I try to make a call it says data network not available and I am unable to send a text or connect to a mobile network. I have tried it with different sim cards from 3 vodafone and orange none of which work. The phone was originally orange, the previous owner was using vodafone and the 3 sim card was brand new from the 3 store so all of them should have worked.
I have looked through some of these forums and found that it is happening to people whenever they carry out the restore factory settings function which is what the previous owner of my phone did to protect his personal data. I have not seen a solution to this problem on any of the forums I have read.
Please help.
