8 Ways to Fix Call Failed Error on Apple Watch

Making calls directly from your Apple Watch is meant to be seamless, but you may encounter the dreaded “Call Failed” message when trying to place a call. This error typically pops up due to connectivity issues between your paired iPhone and Apple Watch that interfere with routing calls properly. While frustrating, there are several troubleshooting techniques you can try to get calls working again on your Apple Watch before needing to replace any hardware. Below are 8 methods to help resolve those pesky call failed errors.

1. Check Bluetooth Connection Between iPhone and Apple Watch

Since Bluetooth provides the critical communication between your iPhone and Apple Watch, first ensure Bluetooth is turned on and paired properly:

  • Open Settings app and tap Bluetooth

  • Confirm Bluetooth is enabled. Enable if disabled.

  • Force restart both devices by holding down the side button and digital crown simultaneously until you see the Apple logo appear on the screen

  • Once restarted, go into Bluetooth settings

  • Make sure your iPhone and Apple Watch show as Connected

This restart refreshes the Bluetooth pairing to restore communication between devices.

2. Check iOS Software Updates

Having the latest operating software and firmware is key for ongoing iPhone and Apple Watch connectivity. Software updates include bug fixes and performance improvements.

On iPhone and Apple Watch

  • Open Settings app and toggle Airplane mode on

  • Wait 30 seconds with Airplane mode enabled

  • Tap Reset Network Settings

Updating your carrier settings ensures you have your cell provider’s latest configurations for optimal connectivity:

  • Tap Carrier

  • If an update is available, install it

  • Restart your iPhone after updating carrier settings

  • Make a test call from Apple Watch

With Wi-Fi Calling disabled, check if standard cellular calls now go through on your watch.
