Is the sim only for watch or for phone as well?

The calling provision on the watch has to come from a phone plan which you must also have.

Have you shopped around to buy the watch seperately as you can still add an airlime plan from O2 to a watch bought elsewhere Fri, 03 Apr 2020 07:13:55 GMT https://community.o2.co.uk/t5/Apple/Queries/m-p/1317261#M163833 PhoneChanger 2020-04-03T07:13:55Z
