I recently bought a HTC One. Everything worked fine including mobile-data and Wifi. Until I once used my phone as Hotspot for my laptop.
The whole time while using the hotspot I had working internet on both my phone and laptop. But the next day (hotpost disabled), I couldn't get the mobile-data to work.
I don't get an error, it just doesn't load.
Wifi connections still work.
Now I tried reenabling hotspot and to my surprise it works. I now have internet on the laptop but NOT on the phone.
It seems that somehow the mobile-data will only work when the phone is used as hotspot.
What have I done wrong?
