If you are in a good hot spot area (don't laugh, I had a client trying to use WiFi and their home had no WiFi and they were confused since it worked at Starbucks.)
Next stop may be the carriers support counter to see what's broke or not setup.
i bought a phone and contract from Car Phone Warehouse on o2 due to appalling coverage I decided to change to EE what a mistake, on my S6 I was able with O2 to use Wi-Fi not so wth EE so here I am with no bars showing and unable to connect to Wi-Fi has anybody any ideas to rescue me, you should be careful what you wish for
