Apple iwatch setting up mobile data

[MIKRIK28]

So I’ve purchased a series 5 iwatch from o2. Can see the tariff on my o2 app. Gone to set it up this morning and when I click on the set up mobile data tab on my iPhone it comes up with “Your o2 account is not eligible to enable mobile data on your Apple watch, Contact o2 for more information”

Question is, is this a time based thing or should I contact o2? I ordered the iwatch on Thursday and took delivery Friday. Rang this morning and they only want people to phone for lost phones or fraudulent activity

You need to call customer service.

The one ending in 4005 works great.

Say anything to get through to an agent.

That’s great thanks for the advice. Managed to get through to an agent who’s carried out an esim reset and should work within 24hrs

I had the exact same issue and spoke to about five different people at O2 who couldn’t solve it. It turns out all I had to do was enable WiFi calling on my account. You can do this in your device settings by logging into MyO2. As soon as it was enabled in my account (pretty much instant), I switched Wifi calling on in my phone settings and it worked. I could then set up mobile data through the watch app.
