Reset watch while calling them get your phone and watch ready for the setup turn your data on not wifi. Now they just have to remove the plan from your account and set it up again but in one number not a separate number if after all that and they still don't understand then get them to get 02 technical support to help. Its a easy setup but the people on the phone are most are working from home and have limited access to system. Or the ability to ask for help instead of help they just do it as its commission for them. But you the customer is left with the issues. I have Vodafone manager on my case as the man removed my sim card from my plan and put it to e sim then set up watch but can't have the two e sims on on device so case manger is involved to fix the issues with technical team. Don't roll over with them and ask for compensation. It's not your fault it is there's. Good luck
