    Hello mekofromga,


    Thanks for using Apple Support Communities.

    iPhone: Troubleshooting issues making or receiving calls



    1. Toggle airplane mode: Tap Settings > Enable Airplane Mode, wait five seconds, then turn off airplane mode.
    2. Ensure that your software is up to date:
      1. Check for a carrier settings update.
      2. Check for an iOS software update.
        Some updates may require a Wi-Fi connection.
    3. If the iPhone has a SIM card, reseat the SIM card.
    4. Reset the network settings: Tap Settings > General > Reset > Reset Network Settings.
    5. Try to make or receive calls in another location.
    6. Attempt to isolate to one network band:
      • If you're having the issue on LTE, disable LTE if possible and try again.
      • If you're having the issue on 3G/4G, disable 3G/4G if possible and try again.
    7. Restore the phone as new.



    Best of luck,
