Connecting iwatch to iphone with 02 sim

[GSA1]

Hi

I have an o2 pay monthly sim only plan, 20gb data, unlimted calls and texts.

I purchased my iwatch and iphone xs max from apple direct.

However everytime I follow the instructions to set up mobile data plan and log into 02 from the phone, it gives me the error message and ref 88

I called o2, spoke to someone who could not help and said call apple lol.

How can apple help its not their data plan, the lady was unprofessional.
so can someone help me, i have reset the phone and watch, still the same thing. It seems o2 has to turn something on I feel???

Make sure you have given permission to motion and fitness to access the watch and if so, keep calling O2 until you get someone who knows what they are talking about.

Hey @GSA1 how are you getting on with this? Are you still having problems or are things sorted now?

O2 Seem useless, they do not know basically. 

I think it is at their end and they have to turn something on at data

It certainly is. The advisory has to reset your i watch plan on their side. Can take up to 24 hours but usually with in 2 or 3. If it takes longer then that you have to call again. I went to the store and even they were totally useless. Told me to call 202 idiots. And to make things worse my data doesn’t work on cellular only calls and texts. What a useless bunch, Apple too
