How to fix an Apple iPhone 6 that can’t make outgoing calls & other call related issues

The problem I addressed in this post is about outgoing calls that won’t go through with the Apple iPhone 6 (#Apple #iPhone6). Anyone who is having the same trouble on making calls on their #iPhone can use this content as guide to troubleshoot the issue. Read on to learn why such problems occur and what must be done to resolve them.


To further explain the issue, I’ve cited a problem on relevant concern sent to us by an iPhone 6 owner who is having trouble making outgoing calls on his iPhone 6.

Problem: “I was able to make outgoing phone calls this morning, however now this afternoon my phone immediately hangs up after one second to any number I try calling. I have rebooted the phone, checked all the places I can think of, including DND, and airplane mode. Nothing helps.”

Possible reasons as to why you cannot make outgoing calls

Among the most common reasons as to why you cannot make outgoing calls on your mobile phone include a misconfigured settings, network unavailability, faulty hardware, and a deactivated account status.

The first thing you should do if all of a sudden you can’t make outgoing calls on your iPhone 6 is to check and ensure your account is in active and in good standing. Some service providers/carriers will deactivate outgoing call services or temporarily reduce phone services in an account to incoming calls only due to late payment or unpaid bills. Therefore, let us make sure your account status has nothing to do with it. After confirming everything is fine with your account, you may begin troubleshooting the problem with the following methods.

Recommended Workarounds

I have outlined a series of troubleshooting procedures that might help you fix an issue on making outgoing calls with the iPhone 6. These workarounds are comprised of manufacturer- and carrier-recommended solutions. That being said, these methods are safe to try on. Anyone who is facing the same dilemma with the same device may likewise, use the following workarounds to fix the issue.

Note: Enabling and disabling of relevant settings on your iPhone, such as Airplane mode and Do Not Disturb (DND) might also be helpful in this situation. Again, Airplane mode and DND feature must be turned off or disabled to avoid calling issues to arise. Although I understand both workarounds have already been done in this situation but to no avail. In this regard, please proceed with other possible solutions as follow:

Step 1: Check for possible outages in your area. Once you’ve verified that your account is in good status, be sure to check for any known outage in your area that might have affected the phone network and services. I strongly suggest you do this first, especially if the problem happens all of a sudden. Also ensure there is no problem with your own telephone line.

Step 2: Ensure your phone is getting a good signal. If the network indicator says No Service or Searching, it means your device is unable to connect to a cellular network or cellular data, and so, outgoing calls won’t go through. In this case, kindly check your coverage area and ensure you’re within range of your cellular network coverage.

Step 3: Verify contact blocking settings. It’s possible that the number you are trying to call is in the block list, that’s why your outgoing call won’t connect. In this case, go to Settings-> Phone-> Blocked, and make sure the phone number is not in the list. Otherwise, remove or unblock that number.

Step 4: Check/update your carrier settings, if necessary. Sometimes, all you need is to update your carrier settings for phone services to work as it should. Generally, carriers’ settings updates contain small files such as network, calling, cellular data, messaging, personal hotspot, and voicemail settings. These updates can include pertinent settings updates from Apple and your carrier. In order to update your carrier settings, your iPhone must be connected to the Internet.

After ensuring it’s connected, go to Settings-> General-> and select About.

You will be prompted with a message, if an update is available. Follow the onscreen instructions to install available carrier updates.

Should you need to know the current version of the carrier settings on your phone, navigate to Settings-> General-> About-> and then view the information next to Carrier.

Step 5: Reset network settings on your iPhone. Some issues including problems on making and receiving calls would just require a simple network reset to properly work again. Thus, you might as well give it a try this time. Just head on to your phone Settings-> General-> Reset-> and then select Reset Network Settings.

Step 6: Try to remove and re-insert the SIM card (if applicable). If you’re using a SIM card, make sure it is properly secured in place.

Step 7: Isolate to one network band. You can also try to toggle between LTE and 3G/4G networks to isolate the problem. If you can’t make calls using LTE, then try to disable LTE and see if it works. Do the same if you’re on a 3G/4G network.

Step 8 : Try dialling *#31#. It shows a message “Setting Interrogation Succeeded, Calling Line ID Restriction Disabled” and then you can call normally.


If you still cannot make outgoing calls after performing all of the aforementioned methods, then please contact your carrier and make sure your calls don’t have errors on their system.
