I have what is maybe a silly question but it does my head in. I have the Galaxy S GTi 9001 with Telfort a dutch provider, when I popped over to the UK I had a full signal strength (all bars up) yet when I tried to phone or sms I got told I didn't have permission to use the network. I had to manually set it to Orange then it worked, when I got back to NL the same problem again until I manually set it back to KPN (used by Telfort) I used the same sim card in my wildfire and never had this problem. Question is how to I setup the GT1 9001 to auto connect to a valid network when ever I go to different countries? I have it on roaming data etc.
