My Apple Watch is not able to make or accept calls

Hello arpan1701,

Thank you for reaching out to Apple Support Communities.

Are you able to make calls over Wi-Fi:

"Make calls over Wi-Fi

If your cellular carrier offers Wi-Fi calling, you can use your Apple Watch to make and receive calls over Wi-Fi instead of the cellular network—even when your paired iPhone isn’t with you or is turned off. Your Apple Watch just has to be within range of a Wi-Fi network that your iPhone has connected to in the past.

To see if your carrier offers Wi-Fi calling, see the Apple Support article Make a call with Wi-Fi calling, and enable Wi-Fi calling on your iPhone.

1. On your iPhone, go to Settings > Phone, tap Wi-Fi Calling, then turn on both Wi-Fi Calling on This iPhone and Add Wi-Fi Calling For Other Devices.
2. Open the Phone app  on your Apple Watch.
3. Choose a contact, then tap .
4. Select the phone number or FaceTime address you want to call.

Note: You can make emergency calls over Wi-Fi, but when possible, use your iPhone over a cellular connection instead—your location information is more accurate. You can do this on your Apple Watch by temporarily disconnecting from Wi-Fi."

More details can be found here: Make phone calls on Apple Watch

If the issue persists, can you provide a few more details? Were you able to previously make calls with your Apple Watch? Do you have a cellular plan on your Apple Watch? Are you experiencing issues with FaceTime, regular calls, or both? Also, which watchOS version do you currently have?

Cheers!
