Phone calls breaking up

Hey Calapo1927,

We'd recommend reviewing the information in this article as it provides steps to take to help resolve issues making or receiving calls which can also help with call quality issues: If you can't make or receive calls on your iPhone

"Update your software

1. Check for a carrier settings update.
2. Check for an iOS software update. Some updates might require a Wi-Fi connection.

Check your iPhone settings

1. Turn Airplane Mode on and off. Go to Settings and turn on Airplane Mode, wait five seconds, then turn it off.
2. Check Do Not Disturb. Go to Settings > Focus > Do Not Disturb and make sure it's off.
3. Check for any blocked phone numbers. Go to Settings > Phone > Blocked Contacts.
4. See if Call Forwarding is turned on. Go to Settings > Phone > Call Forwarding and make sure it's off.
5. Check to see if Silence Unknown Callers is turned on. If the setting is on, a caller must be listed in your Contacts or Recents. Or they must have shared their number in Mail or sent you a message using that number in order for their call to go through. Add their number to Contacts to ensure the phone rings. Calls from some third-party apps might not go through.

Check your network settings

1. Reset your network settings. Go to Settings > General > Transfer or Reset iPhone > 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."

Thanks!
