Q: No Network in iPhone 4S

I keep getting a message saying 'No Network' cannot make or receive calls.

 

I have changed my SIM card and although it doesn't do it as much, it still happens once or twice a day.  I switch the phone on and off and it clears.

 

The phone is an iPhone 4S and is 18 months old and consequently is deemed out of warranty.  Has anyone any suggestions/ideras?

 

Thanks

    Hey there Pault17,

     

    It sounds like your phone is not connecting to your cellular service. I recommend the troubleshooting from the following article:

    1. Toggle airplane mode: Tap Settings, turn airplane mode on, wait three seconds, and then turn off again.
    2. Restart your iPhone.
    3. Ensure that your software is up to date:
    4. Remove the SIM Card and reinsert it. Allow the iPhone to acquire the network again.
    5. If your SIM card has SIM PIN enabled, try toggling it off: Tap Settings > Phone > SIM PIN.
    6. Try another location. If a different location works, but the original location still does not, contact your carrierto report the issue.
    7. Reset network settings: Tap Settings > General > Reset > Reset Network Settings.
    8. Restore the iPhone as new.
    9. Contact your carrier to:
      • Verify that the iPhone is properly set up on the account with the appropriate, current data plan.
      • Verify that there are no account-related blocks.
      • Find out if there are specific error messages in the carrier logs that could help determine why the issue is occurring.

    If none of the above steps resolves the issue, contact your carrier, make an appointment at an Apple Retail Store, or contact AppleCare to troubleshoot further.
