Even when wifi is turned off, the mobile network gives this message "Use phone for data connection when wifi is unavailable". My wifi is turned off and the 3G connection is also strong. With this issue, I cannot access the internet as the browser or ne other app, It says that there are connection issues, My APN settings are correct. But still the issue keeps popping up intermittently. In this condition, with wifi turned off and 3g data connection behaving irrationally, I have no mode of accessing the internet. Is something wrong with the wifi app which makes the 3G connection detect that wifi is on ? I faced the same issue around 10 days back but then it got resolved automatically. Could this issue be with my service provider ?
