I have an active data plan and also enabled data from the phone settings for my Samsung Galaxy Fit (Android 2.2) however my data is not getting switched on. I have tried to reset the phone from Privacy after which it worked for few hours then again it got automatically switched off. I have tried restarted the phone, it gets on for few seconds then gone I verified the APN settings to be correct too I have tried to use the same SIM card on my different phone (hTC Wildfire) and works fine. There is no carrier issue as my wife and I have the same carrier and all works fine on her hTC. Any suggestions would be highly appreciated.
