You know what worked for me...
Switching to airplane, lost connectivity, waited 5 minutes.
Switched the airplane off and I was to select an operator.
Because I'm using Cell C, I always Chose Vodacom for network connection, for better and faster internet access you know, and then I selected home network which is Cell C.
I went to Opera Mini and booooooh!!! It went on, was even able to access every page.
