Hello guys since yesterday I can't use my mobile internet. I checked my APN settings and I didn't find anything which could make any problem. I just use Quick Settings and I used to switch sometimes between on/off in the mobile data. I don't know what's the problem... I even reset my phone and reinstall everything but the mobile internet doesn't work to me. when I tried to enable my mobile data on Quick Settings, for a second the 3G Icon appears on the top of the screen and then it disappears. it looks like something stopps my mobile internet working. someone can help me?
