So, I migrated over from O2 to EE so I could get an Apple Watch series 3. The migration of the phone part went well, SIM transferred over today and now on faster 4G speed 
The setup of the data on the Apple Watch still isn't working - I've spent over 2 hours today on the phone to different support staff at EE each of which have provided different excuses, I mean answers.
I go into the Apple Watch app on the phone, select 'Mobile Data' and then 'Set Up Mobile Data' it then prompts me to login to EE account, this then takes about 3 minutes, then fails with an 'Oops something went wrong message' Any ideas?
