Re-activation of watch esim

Hello rahul1407,

Thanks for using the Apple Support Communities!

In order to activate cellular data on your Apple Watch, you'll first need to ensure that you have active service for it through your carrier.

If you do, the steps in here can walk you through setting that up: Set up cellular on Apple Watch - Apple Support

Take care!

I too faced the same issue when i unsubscribed the JIO Cellular plan from my Apple watch. I followed this article and guess what it works: https://lootmaniac.com/how-to-connect-jio-physical-sim-apple-watch-cellular-prepaid-postpaid-no-esim/

Hope it'll work for you too.
