Good morning each,

Seems as though this is a common problem. 

Despite getting a message appx 4 days ago to inform me that my new watch was associated with my number etc, I cannot activate/set-up my data plan either. I follow all the steps verbatum, but when I click "set-up mobile data, I get a "please wait whilst the page is loading message" appear fleetingly, then an "Ooops, something went wrong, try again...... call 202 quoting error ref code 15" 

This of course is useless as there is no-one there to answer the calls (you go through the preamble of confirming the number and device you want to talk about, then it puts you through to a "we cannot answer you call right now sorry, blah, blah"

My MyO2 account shows the watch etc.

Clicking the mobile data button on my watch brings up a screen showing "no sim, no connection"

Come on O2, you were quick enough to send me the watch and start charging me for the associated plans, please sort this out.....

Or you can have your watch back!
