Purchasing an apple watch/sim only

[Lucy0886]

I currently have a sim only contract with 3 for an iphone 8 plus, I'm trying to order an apple watch with o2 but I'm having a massive problem with this pay monthly account thing. I don't know what I need to order for this to work and (admitedly I'm not great with phones) if I go to order a cheap sim only plan on the site it seems to want to give me a different number or use my number from my 3 sim only contract. I'm concerned that if I put in my 3 number it'll cause issues with my 3 contract so I'm really unsure of how to get around this. Any help would be much appreciated as understandably I cannot get through to o2 contact centre at the minute. Thanks!

You can't use an O2 Apple watch with your Three phone, you do know that?

Hi there, I literally don't have the first clue with phones so be gentle with me. From what I thought I understood was that if you bought a cellular watch with a data plan you could pair it to any phone regardless of what network it was on? Is it that I'd need to take out a sim only plan with o2, put my current phone number on that and use that in my phone to then be able to use an apple watch?

Yes, you need an O2 pay monthly personal account so you'd have to transfer to O2 for your phone.

Can I buy an Apple Watch from O2 if I bought my iPhone through someone else?

Yes, as long as you’re using a compatible iPhone with an O2 Pay Monthly personal account.
