I have a Galaxy S GT-I9000, running Froyo on Vodafone network.
I cannot properly activate data mode and have not been able to do since I got back 2 months ago.
The history is that I travelled in Europe this year and I deactivated data mode. Returning to the UK, I (tried to) reactivate by Settings/Wireless and Network/Mobile Networks and checking “Use packet data” and “Data roaming”. And then Access Point Names/Network Mode/”GSM/WCDMA (auto mode)”
There is no icon next to the signal strength in the status bar. When I am in a good signal area, I cannot access internet where I used to be able to before travelling to Europe. Quickpress the power button brings up the Phone Options menu, and according to that, Data Network Mode is activated. Even in somewhere like Birmingham, I still cannot access 3G internet.
If, instead, I check “WCDMA only”, I get a 'No entry' icon showing (3G is poor coverage where I am just now). But now, I cannot make voice calls.
It seems that GSM/WCDMA (auto mode) has ceased working properly.
Weirdly, during booting up, as the screen is being populated with icons, alternating with status messages about Media Scanning,the “No entry” icon appears briefly, but at that point, the signal strength has not appeared. Shortly afterwards, I do get the 3G icon appear next to the signal strength, but by the time everything has settled down, the 3G icon has disappeared again.
Can anyone help me, please, because I am stumped!!
