I can't use mobile data on my Samsung Galaxy Watch Ultra (2025) Wear OS 6
Cause 1 of 4: Your smartwatch isn't correctly set up for mobile data.
Several functions on your smartwatch use mobile data, e.g. when making or receiving calls, sending email messages and listening to music on streaming services.
Solution: Set up mobile data on your smartwatch.
