iPhone data connection problem

[The Ouzo]

quieten down Android boys, this thread is not for you.

 

Last week my stopped receiving calls and SMSs. Logged a call with CellC, we tried all sorts of resets but nothing worked. Put my sim in my old phone and it worked, so put it back in the new phone and did a factory reset. Calls were working again.

 

But then I noticed another problem had cropped up. If my phone switches between wifi and LTE or even different LTE towers data throughput stops. To get it working again I need to turn airplane mode on and off.

 

The internet suggested a network reset which I grudgingly did (you lose all your wifi passwords). It has not helped.

 

I suspect the culprit to all of this is the work wifi. It all started when I connected to it. Its hosted by clickspot and is one of those where you need to login via a webpage and leave that page open whilst you browse.

 

Has anyone experienced this and found a fix ?
