Hi
I also have the same problem with using my Sony Xperia abroad. I had issues in Prague last year, which I put down to being a blip and then issues again in Berlin this year. I went onto the online help chat through wifi whilst in Berlin and followed all of the instructions but it didn't work, went back onto the chat about 4 times and what they were telling me to do didn't solve the problem. Everytime I tried to connect to the internet it would say roaming data not enabled but it was switched on. I tried each of the network providers coming up in the list and wasted way too much time of my trip trying to solve the issue. Phoned my network provider when I got back and they said all of the connections were fine so it wasn't there issue and to go back to where I bought my phone. Carphone Warehouse were very helpful and checked all of the settings, one of the guys even said he had the same problem and gave me a number to text when going abroad and also suggested a factory reset at home, but other threads have said this doesn't work. I have done the advice in this thread and will soon be going to Poland so I am hoping that my phone will work but I suspect not from what other people have said. So now we're all stuck with this issue. My network provider won't let me out of my contract unless I pay and Sony just give advice that doesn't work. I had been happy with the phone as I bought it due to the quality of the camera but I don't think I'll ever buy one again, having switched from Samsung that I didn't have any issues with it's been a learning curve.
So Sony, do you have a fix to this widespread problem yet?
