Begin by opening the Apple Watch app on your paired iPhone. Navigate to the “My Watch” tab and select “Cellular.” If your carrier supports Apple Watch cellular plans, you will see an option to “Set Up Cellular.” Tap this to start the activation process.

Follow the prompts provided by your carrier to add a cellular plan to your Apple Watch. This often involves signing into your carrier account, selecting or confirming the plan, and agreeing to any additional charges. Some carriers may require you to scan a QR code or enter an activation code.

Once the eSIM is activated, your Apple Watch will display a cellular icon in the Control Center when connected to a cellular network. Activation time can vary depending on the carrier and network conditions, but it typically completes within a few minutes.
