My Apple Watch isn’t supported jio mobile data in india region. But why ????

Where did you buy your Apple Watch.

The above message use a UK web site, which if you got the Apple Watch in the UK, it should still work.

But if you got the Apple Watch in North America (Canada, U.S., Mexico, Puerto Rico), it will have the wrong radio and will not work in India.

Hello Abhi3232,

Thanks for posting in Apple Support Communities!

We see that your Watch is not supported by your mobile data plan.

We’d be happy to help you!

We’d recommend referring to Apple Watch - Carriers - Apple to see which carriers are available to use.

Take care.

Abhi3232,

Thanks for following up.

Since you have the Series 3 GPS+ Cellular, we'd recommend contacting your carrier to see about the cellular plan compatibility.

Cheers!
