Phone disconnects calls when I answer

I’m having an issue with my 8 plus. When I answer calls from a particular number, the line disconnects. I have reset network settings , checked my block and do not disturb settings. Restarted my phone — updated carrier settings nothing is working. Help!!

Hi canonero,

Thanks for using Apple Support Communities. From your post, I see that you're unable to answer calls from a particular caller.

You've done some great troubleshooting so far. There's a possibility that the issue is on the end of the caller if none of your other calls disconnect. Are you able to successfully make a call to them?

While you've completed a few of these steps, there are a few more that will help rule out issues on your end. You can find them in the article titled If you can't make or receive calls on your iPhone :

Remove and reinsert your SIM card

If your iPhone has a SIM card, remove the SIM card, then reinsert it.

Contact your carrier

When you contact your carrier, make sure that:

  • Your account is set up to use your iPhone.
  • There aren't any localized service outages.
  • Your account doesn't have a billing-related block.
  • Your calls don't have errors on the carrier system.

Check your network settings

  1. Reset your network settings. Go to Settings > General > Reset > Reset Network Settings. This will erase all current saved settings, including Wi-Fi passwords, preferred networks, and VPN settings.
  2. Try to make or receive calls in another location.
  3. Switch to a different network band. Go to Settings > Cellular > Cellular Data Options > Enable LTE and turn off Enable LTE, 4G, or 3G (this option will depend on your carrier and device model).
Since you've already reset your network settings, you can skip that one, but the other two are great recommendations. The steps above will help make sure that things are working as expected on your end.

I hope this helps.

Have a great day.
