I can not make outgoing calls on my iPhone 6

i don't know what happened to my phone, i can receive calls, but can't make any phone call, i can send and receive text messages, i can use my mobile data, BUT CAN'T MAKE A SINGLE CALL TO ANY NUMBER. thanks though. it worked

I have a similar problem with a difference. I bought a new iPhone X which works fine. I am repurposing my iPhone 5s so I can use it for WiFi calling around the house. I can receive but not make calls.

Any suggestions for this scenario?

I tried all of the above.

Thank you

Hello Veardmotorcraft,

The steps detailed below can help restore your iPhone's ability to place phone calls.

1. Toggle airplane mode: Tap Settings > Enable Airplane Mode, wait five seconds, then turn off airplane mode.
2. Check your phone settings:
   • Check your Do Not Disturb settings: Tap Settings > Do Not Disturb.
   • Check for any blocked phone numbers: Tap Settings > Phone > Blocked.
   • See if Call Forwarding is turned on: Tap Settings > Phone > Call Forwarding.
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.

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

Cheers

The solutions offered by Allen A did not work for me, I tried them all 😟 I did what varuntyagi said and it worked like a charm!
I have been SO frustrated trying to make outgoing calls. Thank you so much! Brenda

I've been frustrated with this problem. Airtel (carrier) couldn't help me. Just now I tried all the steps mentioned by Allen. It didn't work. But nevertheless, thanks Allen. Then I looked at what Varun had mentioned. I thought it can't be that easy. But! Phew! it worked. Thanks a lot Varun. You are my rockstar! keep up the good work Apple community

Dialling *#31# worked! yay! Thank you varuntyagi Brenda

I tried everything and FINALLY *#31# worked!!! Thanks so much. It's a new replacement phone and I could receive calls but couldn't make any outgoing.. Thanks so much for the help!

#31# worked for me. Before the #31# fix, what was unusual is, I could receive calls and I could FaceTime, but I could not call out. When attempting to call out I would immediately get the message "Call Failed" with options to Cancel or Call Back. Call Back immediately would result in an instantaneous "Call Failed". I went to the Apple Store and diagnostics didn't show anything other then a failed sim card when the sim card was inserted in another phone. So I went to Verizon and they replaced the sim card and the next day the problem returned. The phone had started working on its own when I went to the Apple Store. It was almost like walking into the Apple Store fixed the phone, but the problem returned the next day.

varuntyagi's post said *#31# was the fix, but the *was unnecessary for me and in fact caused the fix to fail. #31# worked.

Than you Varuntyagi.

Another option is to simply switch off the iphone and then switch back on again. This worked fine for me when all else failed.

Shutting the phone on and off, or doing what is called a reset did not help. If you look at my May 8th post I had put a new sim card in and even had the Apple Store run a diagnostics on my phone, yet the problem persisted. The *#31# worked once for me, but the problem returned the next day and the *#31# stopped working for me. Doing steps 1 & 2 of Allen A's post did however work for me and the problem has not returned since. I'm beginning to wonder if this wasn't connected to my Apple Watch which after turning Airplane mode on and off on my iPhone 6, I found that my Apple Watch was in Airplane Mode. I switched that off and have not had any problems calling out since. I will report if the problem returns.

*#31# works

*#31# worked for me. Thanks Varun. Can't figure out why it happened in the first place.

I live in India. I own an iPhone 6S. Here is what my problem was. I got a spam call. Though I did not answer it my phone suddenly stopped being able to dial out. I used the solution *#31# and presto its worked. Thankyou. But how do I ensure this is not repeated.

Tried even changing sim.

But once on roaming, I've not been able to make calls.

I was thinking of junking the Iphone.

But *#31# worked.
