Q: Why do I keep losing signal on my iPhone 4S and it keeps ending my calls

My iPhone 4S has been playing up for days now , I'm barely on a call for a minute and my phone call ends,

It's so frustrating, I keep getting no service on my phone then it goes to full bar it's never had this problem before,

Is anyone else having this problem

 

Thanks

    Hi Jtink13,

     

    Thanks for visiting Apple Support Communities.

     

    It can definitely be frustrating to encounter dropped calls or service issues. I'd recommend starting with these steps to troubleshoot the issue:

    Follow the steps below to resolve this issue. Please test after each step.

    1. Toggle airplane mode: Tap Settings > Enable Airplane Mode, wait five seconds, then turn off airplane mode.

    2. Check your phone settings:
    3. Ensure that your software is up to date:
      1. Check for a carrier settings update.
      2. Check for an iOS software update.
        Note:         Some updates may require a Wi-Fi connection.
    4. If the iPhone has a SIM card, reseat the SIM card.

    5. If the iPhone 4 or iPhone 4s is on the Verizon network, dial *228 from the iPhone and select option 2 to update the Preferred Roaming List (PRL). The PRL determines the cellular towers the phone uses for cellular service, selecting those with the best signal strength.

    6. Reset the network settings: Tap Settings > General > Reset > Reset Network Settings.

    7. Try to make or receive calls in another location.

    8. 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.

    9. Contact the carrier to check the following:
      • Your account is properly configured to use the specific iPhone that has the issue.
      • There are no localized service outages.
      • Your account doesn't have a billing-related block.
      • Your calls don't have errors on the carrier system.

    10. Restore the phone as new.

    If the above steps don't resolve the issue, go to an Apple Retail Store, carrier, Apple Authorized Reseller, or contact AppleCare to send the phone in for service.
