Unable to purchase data plan for Apple Watch ultra

[Buz52]

Hi,  purchased an Apple Watch ultra from apple direct and have a 12 pro max. Ported my number from Tesco mobile to o2 in order to get a cellular contract for the watch. Number port went through fine last week, but when I try to enable data via the watch app on iPhone I keep getting error 106 and not able to get to point where it asks for you to sign in to My o2 to purchase a plan. Customer services unable to help and neither were colleagues in o2 shop. I have updated carrier settings, turned on wifi calling and Bluetooth etc. reset the the Apple Watch, but still no joy. Apparently 202 colleague has escalated to tech support, but no contact from them as yet. Any ideas?

Hi - have you had any update on whats happening with this issue? I’ve had this issue for well over 2 months with no progress or information as to what the problem is. I’ve tried everything and have spent hours upon hours on o2 support line with no progress. Maybe o2 doesn’t support data tethering on the Ultra
