I was given my son's HTC Desire (2 yrs old) in February. He had it on a Vodafone 2-year contract, so when that ended, he did a factory reset on it and gave it to me. I put my Tesco O2 pay as you go sim card into it, that I had been using in a Nokia flip (non Android) phone, and it worked fine for a few weeks, then one day I couldn't get any sort of internet connection except via wifi. I have recently been in touch with Tesco helpline, who helped me set up the APN, but they still couldn't get the phone to connect to the internet. They said that Vodafone need to unlock it.
Is this correct, because it is only the 3G/2G connection that I can't get. Everything else is fine. Does it need unlocking? Do I need a new payg sim card? Is it a Tesco/O2 problem? Is it a Vodafone problem?
You advise would be greatly appreciated.
