Samsung Galaxy watch 6 pairing problems with pairing plan

[Sam17]

Hi Im using android phone and i bought new galaxy watch 6 classic 4g version but when I'm trying to pair data plan its showing me 3 doesn't provide data plan for your watch and error code -1 if anyone knows about it how to use galaxy watch please help?

I do not have an add-on for this in my account I have spoken to several people at three today and have been round in circles no one seems too know. I asked to add the add on for smaller watch been told because I don't have a Samsung you can't do this. Can someone help please 

Thank you.

Save yourself a lot of time wasting and disappointment and just give up now, you won’t get this resolved.

having finally come to that conclusion I made some enquiries about moving my number, the person on the end of chat said, oh there’s no problem just take out a new sim contract with 120gb data per month and device sharing will be on it. It was laughable, no idea of the problem, just wanted to sell a new contract.

the long and short of it all is that if you don’t see the option in the wearable app (in data plans) then 3 don’t know what to do. Give up. Go elsewhere.
