iPhone 4s call failed, how to fix

Several users have reported problems when trying to make a call. The reported problems include, but are not limited to, call failing and no sound.

Fix

There has been similar Siri related problems with outgoing calls where there is no sound while a connection is established. It has been reported that updating to the latest iOS fixes this problem.

If you have a call failing issue and updating your iOS does not fix your problem, try each of these steps until you resolve your issue:

  • Make sure that you are in range of the cell network by checking cell signal indicator bars.
  • Reset your network by tapping  Settings > General > Network
  • Reset your iPhone by holding down the sleep and home buttons until the Apple logo appears
  • Try Settings > phone > show my caller ID. Just visit and let the device load your settings.
  • Try disabling airline mode.

      Try this

      General- Date&Time- Set Automatically Turn it OFF

      the set the Time Zone to THE PALCE WHERE YOU BOUGHT THE IPHONE After that just change the time to your current time !!

      For an example i live in sri lanka but i bought the iphone from singapore so i changed the time zone to singapore and adjusted the time to my local time and IT WORKED :)

    Same here.

    The phone was working fine until yesterday. Outgoing calls Failing with error “Call Failed”.

    Earlier the phone was not working at all. No Outgoing. People calling me could hear the ring, but the phone at my end was not ringing. I updated the Firmware to 5.1 and I started getting incoming calls and SMS started to work.

    I finally restored the phone, yet no luck.

    The only thing what I did yesterday was I checked a friend’s New Micro SIM in my phone.

    Any suggestions :-( ???

    Thanks

    If the Show My Caller ID option inactive, you cannot change this option for some reasons. You can use cydia tweak called Caller ID SBSettings Toggle to change caller ID option on iPhone.

    This works for Me

    “•Try Settings > phone > show my caller ID. Just visit and let the device load your settings”

    • Yuki says

      but why!?

    call only FAILS TO ONE SPECIFIC NUMBER !!!!!!!! WHAT THE HELL, WE DONT HAVE ANY APPLE STORES IN NAMIBIA AND ITS A BRAND NEW PHONE

  5. sid says

    this works, but this is not a permanent solution. Every time when you turn off mobile power and turn on the problem continues. and you need to do all above things

    Will apple find a permanen solution???

  6. Ry says

    Worked for me. It’s reoccurred a few days later so just did it again and still worked. I have a iPhone 4S from Australia and trying to use it in India

    I am with tmobile and have the 4s, phone displays full signal and has the operator name on screen. Calls fail and no incoming calls can get through. The only way I can fix this is by turning phone off and on. As the phone displays signal as full when it actually is not connected to the network, I can not tell there is a problem until someone tells me my phone is off or I try to make a call and get the call failed message. Complained to tmobile tested new sim still problem. Tested sim in other phone not apple, no problems. Advised to contact apple done so explained problem and what I have done to try and rectify problem. Told it is a fault with the phone, they booked me in to exchange for a new one. Less than 1 months warranty left. That’s good service.

  9. Dirk Loots says

    • akshay says

      i was able to call until morning when suddenly my iphone showed error CALL FAILED.
      I inserted my sim into my colleagues phone in order to verify whether it was a sim problem or iphone issue.
      and guess what i was able to call without any problem as a result no problem in the sim.
      then i re-inserted the sim in my iphone in haste and checked the settings: settings>phone>show my caller id. let your iphone load its settings.

      tried calling and it worked (y)!

    I have had the same problem, tried absolutely everything and it’s infuriating. The fact that this is clearly an iPhone issue and that it’s been going on for ages without apple paying any attention makes me want to start an anti-iPhone revolution. They need to take care of their customers not just ride on profits from loyal followers. Anyhow, reading through all the fixes, I only found one that works for me… Turning off the 3G. When I turn it off, I’m able to make calls again. It’s not ideal, but while I’m still locked into this contract it will have to do. For now, I’m working on transferring everything from my iPhone elsewhere so that I’m ready to change when my upgrade is due. It’s been increasingly unreliable with notes and numbers being lost when the last update was done. Anyhow, enough ranting, good luck!

    I had a problem of call failed in my iPhone 4S.i on the SHOW MY CALLER ID to ON.in phone option.now there is no problem…

  15. Yuriy says

    Thanx all, worked the time thingie on 4s, rest didn’t work, restoring, caller Id inactive cant change :-) iOS 6.1.3 but time changing to manual worked for some reason :-)

  16. Emily says

    Nothing is working for me. The only thing I haven’t tried is restoring my iPhone. I’m hesitant to do so because of losing everything. Bottom line, I’ll never buy a product from Apple again. Too many issues, starting with the power button getting stuck and unable to work.

  17. says

    It works.

    Mine is an old 3GS phone.

    1. I set the manual date and time (Settings > date and Time > Manual date and time
    2. Set My called Id as well as it was off and left blank (Settings > Phone> Show my caller ID (this was left blank as I had reset all settings. Also, my phone number was not inputted, so i did that and its working fine)

    Thanks to this forum, my Monday and subsequently the entire week would have been otherwise ruined coz i thought that this problem is from a loose wiring or a scratch on the SIM
