Iwatch No Sim

[CatChamp]

Hello. I am unable to set mobile data on my Cellular Apple Watch with my O2 service. I tried the guidence on the O2 website:

Open the Watch app on your iPhone and tap on ‘Mobile Data’.
Then tap ‘Set up mobile data’. You’ll be prompted to sign in with your My O2 username and password.

If I try that, it says:

Apple Watch on O2 is only available to personal Pay Monthly customers.

We’re just customers like you but it sounds like you’ll need someone to access your account which can’t be done from here. If you message O2 on Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG) , they should be able to help you with this
Thanks

I have tried Customer Services on multiple occasions but have now resorted to issuing a complaint as no one has been able to resolve my issue 2 week on

Just to confirm @CatChamp , you have a current pay monthly personal account with o2?

Either a sim only or with device? And not a business account?

[CatChamp]

That is correct   I have a personal pay monthly account . I have just noticed that the IMEI on my O2 account does not match that of my device would that matter ?

@CatChamp 

As long as the IMEI relates to an iPhone it will be OK.

If it's a different type of phone it will be an issue.

[CatChamp]

my device is an Iwatch the IMEI relates to an iPhone 7 which I’ve never had ??

@CatChamp 

What phone are you using with O2?

[CatChamp]

iPhone XS Max
