Error code 90 / 900 Apple Watch cellular - FIX!!!

[DanWolff]

So I’ve called 202, messages o2 and gone in to both Apple and O2 today trying to connect an o2 Apple Watch cellular plan with my Apple Watch Ultra 2. 

I’m an existing o2 customer with an iPhone 16 pro max. I bought both the phone and Apple Watch privately. Not through Apple or O2. 

upon speaking to an O2 advisor in store today / I was informed O2 are AWARE of the codes and are AWARE it doesn’t work. 

o2 know you can not link a cellular plan to your Apple Watch if you didn’t buy your watch and plan through them. 

basically - the only way to get an O2 cellular plan working on an Apple Watch is to be an existing o2 customer AND buy the watch and cellular plan though o2!!!! 

this feels completely illegal and I’m shocked to have been told this today. I’m starting to look in to how to raise this with the ombudsman but thought it worth posting for others to be aware

You were told wrong. We have people here who have bought from elsewhere and have connected.

However, if you search posts on here you will get the impression O2 customer service haven't a clue when it comes to these watches 

As customers, all we have here are these guides

I’m afraid I wasn’t told wrong. The o2 rep in their o2 London store confirmed it’s a known issue at o2 and they’re also aware they don’t have a solution.
I’ve followed countless “solutions” including what you’ve shared and nothing works. happy to be proven wrong… 
Everything you’ve posted makes no reference to error code 90 or 900 fyi

oh and to add fuel to the fire… the rep (who is commission based) told me to either A) take my watch back and buy through o2 where it’ll then work or B) leave o2 and take out a new sim only plan with Apple Watch cellular plan with another provider such as Vodafone or EE!

May Help??

Solved: Apple Watch Code 90 - O2 Community

Appreciate it but I’d seen and tried this too… nada I’m afraid

Have you tried the O2 Social Media team? The guide posted above ( Activate Apple Watch Guide  ) recommends that approach in most places when the error code persists, @DanWolff.

Links just below work best: use either one, and persist until an agent engages.

BTW, an Apple iWatch and an Apple iPhone from O2 are just as likely to be troublesome as those from any other source.  Good luck!

I think he is away at the moment but @madasaf1sh deals with hundreds of these in his business life. Maybe he can advise

[DanWolff]

Thanks pgn 

I’ve not tried social mainly as I don’t have any of the channel - I have access to Facebook which I’ll try but I assumed they’d be as useless as chat / phone and in person.

Once you get one working on your issue, they are pretty good. That said, the watch-to-phone thing seems particularly challenging for O2 generally, so your mileage may vary @DanWolff 

[DanWolff]

Appreciate the heads up. Am on to them now so will keep you posted
