Honestly 02 is a joke

[Kira-Marie]

I had an Apple Watch Ultra 2 which we just managed to get the sim plan through technical team, I’ve now upgraded and can’t get the mobile service working because all it says is “We believe you have an existing watch plan but we are having difficulty locating it. Please call 202 for free from your O2 mobile, quoting reference code 901.”

I have called 02 so many times and they’ve not helped once and said someone would call but don’t. So frustrated

Hello welcome to the o2 community @Kira-Marie 

Sorry to hear your difficulties.   I don't think o2 customer services will call you.

You may be better sending a message to the social media team, if that suits you.

All ways to contact o2 here:

This includes the social media teams

Would love to help but we are bereft of O2 staff here.

Try the UK based Social Media team on Facebook or Instagram

Do you have a physical sim in your phone or an esim?

Customer service need to close all existing data plans for your watch as you won't be able to reconnect to your existing plan

Once that is done you can go ahead and complete a new data plan and connect your watch
