iPhone stopped making/receiving calls

[KD]

Hi all, 

Suddenly my iPhone will no longer ring out or receive calls?! 
If I try to make a call it looks like it’s ringing out but is silent and doesn’t connect. Does show in outgoing call list. 
Receiving calls, don’t show in missed calls list, rings out for others then to voicemail. 
Texts still fine etc. 

Already checked: Volume, silent, focus, accessibility settings, ringtones, SIM card works in another iPhone, my iPhone works with another sim too, payment is fine and current. 

Anyone who can throw any light on what could be happening? I confess it’s doing my head in now 🤯😂

Hi @KD 👋
I am with another network and recently saw this on their Community posts with regards to an answer for iPhone owners who had the same problem of not being able to make/receive calls......

Iphone users I have managed to fix it on my Iphone…. If you are using an Iphone with IOS18 open settings, select apps, scroll down and select phone, and where it says “My number” type your number starting with a 0(zero). Then click save. Try to make a phone call. Worked for me straight away.

Hope this helps x

Thank you Decembersangel, 

I tried that but it wouldn’t allow me to change from the +44 option. 
I’ve spoken to Smarty help since who after lots of checks, identified that the vOLTE setting was not selected. That seems to have solved the issue, fingers crossed. 
Thank you for trying to help x

Hi. I am unable to receive normal calls. I get no missed call. Where do I find this VOLTE eating to turn on pls?

Which iPhone is it?

@Kulvinder_95921  If your iPhone is younger than iPhone 5, then it should work automatically - you do not need to do anything other than check Settings>Mobile Service>Mobile Data Options>Voice & Data set to 5G Auto and all should be fine.

Have you checked Coverage for your area as well as Network Status for any local mast problems?

I just started using my new iPhone a few days ago and I have the same problem with my sim card. I can't make or receive any calls. No matter what I tried to fix the issue I still cannot call or receive calls at all. This is so frustrating!

@DanielA_3061761  From what you say, the sim was working in your old phone - correct?

This leaves the possibility that either it was not inserted correctly in the new phone, or damaged while being transferred, or the new phone settings are not correct.

Perhaps you can check that the phone shows Smarty network.
