Add data plan in watch SE

Then contact your cellular provider.

Where did you get the watch?

If like so many people in your part of the world, you got a watch from the US, it will NOT work on cellular providers outside of North America.

And...? What did your cellular provider say when you reported the problem to them?

You have not given us any information at all that could be useful in troubleshooting your problem.

We have no idea what model phone/watch you have, what version of iOS/watchOS you're running, what country you're in, or what carrier you're using, and if you're getting an error message of some kind, we have no idea what it says.

“If like so many people in YOUR part of the world”…..? I was under the impression that this is everyone’s world. A simple “contact your carrier” would have been sufficient. But thank you for helping others.

What did your cellular carrier say when you contacted them?

You do have a cellular watch, right?

Hi Thara2020!

I hope your carrier helped you figure out the issue you were having. :)

Seriously? Now we're not allowed to recognize that there are differences in different places?

You posts add absolutely no value to this conversation.
