Getting the “com.apple.mobilephone error 1035” when trying to access your voicemail on iPhone? Don’t worry — this is usually a minor glitch tied to Wi-Fi Calling or a temporary network hiccup. Here’s how to fix it quickly and get your voicemail working again.
1. Turn On Airplane Mode, Then Turn It Off
This trick forces your iPhone to reset all wireless connections, which can resolve temporary signal issues.
Here’s how:
- Swipe down from the top-right corner of your screen to open Control Center.
- Tap the Airplane Mode icon to turn it on.
- Wait 10–15 seconds.
- Tap it again to turn it off.
Once your phone reconnects to the network, try using voicemail again.
2. Turn Off Wi-Fi Calling
Sometimes, Wi-Fi Calling can interfere with how voicemail works. Disabling it might clear the error.
To turn off Wi-Fi Calling:
- Open Settings.
- Tap Cellular or Mobile Data.
- Tap Wi-Fi Calling.
- Toggle it off.
Now, try checking your voicemail again.
3. Set Up or Reconfigure Voicemail
If you’ve never set up your voicemail — or something went wrong during the setup — you’ll need to do it again.
To set up voicemail:
- Open the Phone app.
- Tap Voicemail in the bottom-right corner.
- Follow the on-screen instructions to complete the setup.
Once setup is complete, test your voicemail to see if the error is gone.
4. Reset Network Settings
If none of the above worked, resetting your iPhone’s network settings can resolve deeper configuration issues.
Here’s how:
- Go to Settings.
- Tap General.
- Scroll down and tap Transfer or Reset iPhone > Reset.
- Select Reset Network Settings.
- Enter your passcode, if prompted.
- Tap Reset Network Settings again to confirm.
After the reset, reconnect to your Wi-Fi and try using voicemail.
