Apple watch Cellular

Hello srajeev0001,

Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can. We understand you're having issues with international roaming on your watch. As shown in the message, it does not support international roaming. You would need to set it up with a local supported carrier: Use Apple Watch with a cellular network - Apple Support

"With Apple Watch with cellular and a cellular connection to the same carrier used by your iPhone, you can make calls, reply to messages, use Walkie-Talkie, stream music and podcasts, receive notifications, and more, even when you don’t have your iPhone or a Wi-Fi connection.

Note: Cellular service not available in all areas or with all carriers.

Add Apple Watch to your cellular plan

You can activate cellular service on your Apple Watch by following the instructions during the initial setup. To activate service later, follow these steps:

1. Open the Apple Watch app on your iPhone.
2. Tap My Watch, then tap Cellular.

Follow the instructions to learn more about your carrier service plan and activate cellular for your Apple Watch with cellular. See the Apple Support article Set up cellular on your Apple Watch.

Turn cellular off or on

Your Apple Watch with cellular uses the best network connection available to it—your iPhone when itʼs nearby, a Wi-Fi network that you’ve connected to previously on your iPhone, or a cellular connection. You can turn cellular off—to save battery power, for example. Just follow these steps:

1. Touch and hold the bottom of the screen, then swipe up to open Control Center.
2. Tap , then turn Cellular off or on.

The Cellular button turns green when your Apple Watch has a cellular connection and your iPhone isn’t nearby.

Note: Turning on cellular for extended periods uses more battery power (see the Apple Watch General Battery Information website for more information). Also, some apps may not update without a connection to your iPhone.

Check cellular signal strength

Try one of the following when connected to a cellular network:

• Use the Explorer watch face, which uses green dots to show cellular signal strength. Four dots is a good connection. One dot is poor.
• Open Control Center. The green bars at the top show the cellular connection status.
• Add the Cellular complication to the watch face.

Check cellular data usage

1. Open the Settings app  on your Apple Watch.
2. Tap Cellular, then scroll down to see the amount of data you’ve used during the current period."

We hope this helps.

Cheers!
