Do you all have face this kind of issue? My version is OS 2.5.5, I am facing this issue quite a long time. I unable to make a call and browse a web as it will be none data mode, or I failed to call for the 1 or 2 times after that the data and network will be reload again and it can call again, I mostly face every days. Do you all have this experience or someone know how to solve it?
