Hi all, I've had a Samsung Galaxy Ace since July. I bought it from Carphone Warehouse and it has an O2 sim card in it, which is working fine except for the fact that I can't get on the internet! The WiFi is working okay, but there is no 3G, 2G or anything else (I don't understand most of this technical stuff so bare with me!) Under Settings > Wireless and Network > Mobile Networks... Data roaming is currently switched off, but having it on makes no difference. Under Access point names '02 WAP Prepay' is selected, which is the only option given. Network mode is currently GSM/WCDMA (auto mode). I've tried it on GSM only and WCDMA only (which are the other two options given) but it doesn't change anything. I don't know what else to do. In almost 3 months it has never once shown any sign of connecting to the internet, WiFi aside. I haven't even sync'd it with my Google account yet since I'm never anywhere with WiFi and time to do it! It's not location though because I've tried it in loads of different places all over the UK. Please help!
