I sometimes surf the internet with Web Browser or Opera on my phone for a bit when all of a sudden, it stops working. It starts to work again after I do a hard reset. The next time it happens, I will post the error message that shows up when using Opera.
I have the same problems with outgoing calls too. At some point, it would say "Calling" for a very long time. For this problem, I either turn off the Mobile Network then back on. If that doesn't work then I do a hard reset for it as well.
