Hi, I'm really frustrated!!! Having bought my son a secondhand Samsung S2 (unlocked) last year, I bought a Virgin sim card on their rolling £5 essentials package. He has used it for a year or so. The charging port went and I look it to an official Samsung repair shop and they changed the port. Last week however, we noticed that his phone wasn't registering on the virgin network. I took it back to the shop thinking it was a software problem with the phone and they managed to connect it immediately, however, when we bought it home, it lost connection again. I phoned Virgin and they suggested that they send us a new sim card which I registered with Virgin over the phone (as the phone wasn't able to connect with Virgin) - incidentally, Virgin appears on the phone but the message reads 'unable to register with Virgin'. The new sim card has been in the phone for 24 hours and it still won't connect with the virgin network. My dad has this same ongoing problem with Virgin as we speak. I feel it only fair that Virgin give us a proper explanation as to what the problem is. Otherwise I'm leaving!!!!
We went out on the motorway and came across a huge mobile phone mast. The phone managed to connect to Virgin and the phone received a few text msgs however as we drove past, the phone disconnected again even though when I tried to connect to network, all other networks appeared. There are signal bars but they come and go and I haven't given them too much attention.
I cant speak for the other phone but for the S2 the fact it worked up untill the repair makes me think the antenna either wasnt reconnected or was left loose and has since detached through normal everyday movement of the phone.
