Apple Watch Ultra Cellular Activation

[Tobias1]

Hi, 

I have a pay monthly SIM only plan with O2 (30GB data, unlimited texts & minutes). I use the SIM in an iPhone 14 Pro Max that I bought from the Apple Store Online.

I recently bought an Apple Watch Ultra from the Apple Store Online. I would like to add the Watch Airtime plan for £5 a month to activate the cellular function of the Apple Watch. 

When I try to do this using the 'Set Up Mobile Plan' in the Apple Watch App on my iPhone I receive the following O2 error message:

"Oops, something went wrong. Try again and if the problem continues call 202 for free from your O2 mobile, quoting reference code 106".

I have contacted O2 customer services, the technical team, the retentions team and the sales team. Each person either suggests another team needs to speak to me or that the only way to activate cellular is to buy the watch directly from O2. I don't believe this to be the case as the Watch Help page here:  Apple Watch | Help & Support | O2 suggests that I should be able to buy an Airtime plan on an Apple Watch I already own.

It would seem strange that the cellular function on an Apple Watch cannot be used unless bought directly from the network provider. Can anyone help?

Hi. No sadly no solution. Went round and round different O2 teams and no one can help. Any guidance you discover greatly appreciated as over 3 months now. Only reason I moved to O2 was to use data on my watch! Very frustrating.
