Apple Watch - error code 04

[Tun76]

I recently bought a new iPhone from apple. I paired the watch to the new iPhone. I went to setup mobile data, but gave me error code 49. After hours on the phone to 202, I got nowhere. After an hour in an o2 shop, I was told they had it sorted, and I had to wait 24hours for them to reconnect the data plan to my watch. 
72hrs later, I received a text to say my watch has been connected to Apple Watch airtime plan. 
So went to setup the data plan on the watch app, this time I get told error code 04, and still can’t connect….

can anyone help with this. The Apple Watch has only been associated with the same phone number. I’ve tried resetting Watch and repairing since, and the phone etc etc but getting nowhere. A week later I’m no further forward, an am tied into a paying for a service that I can’t use!

2 things you must have are a direct debit setup to pay the bills from and wifi and 4g calling active and turned on.

The watch is still associated with the previous phone

Customer service need to unattach it from that phone

Hey @Tun76 did you manage to sort this issue yet?

No, still isn’t sorted. I spent 3hrs on the phone to o2 on Saturday as they kept hanging up after 30mins. Finally spoke to someone that says they call me back within 3 days…

Received a phone call today. There were 2 e-sims registered to the watch. Took all of 5 minutes before I got the text to say it’s all sorted. If anyone else has this problem, be patient and persistent, and you’ll get it sorted in 9 days…
