"There is a problem with your Apple Watch"

Hi iamfahadzafar,

Thanks for reaching out in Apple Support Communities. I understand from your screenshot that you're having trouble activating your Apple Watch to use with your iPhone. I can see why you'd reach out about this; I'd like to help. Try these steps first:

• Verify your iPhone is updated to iOS 13.3.1: Update your iPhone, iPad, or iPod touch
• Make sure both Wi-Fi and Bluetooth are enabled: Use Bluetooth and Wi-Fi in Control Center
• Restart both devices:
  • How to restart your Apple Watch
  • Restart your iPhone
• Try to pair and activate your Apple Watch again

If you continue to have trouble reach out to your carrier to verify there aren't any issues, then contact Apple for additional assistance: Get Support

Best Regards.
