Why do my iPhone calls keep failing - "Call Failed" error

Yesterday my phone started saying call failed anytime I tried to make a call, when someone calls me it goes straight to voicemail. Everything else works, I can text, use all apps. I contacted my carrier & they said bring it to a store after we tried several things.

We tried turning airplane mode on & off, resetting the network, removing the SIM card, forcing it to shutdown, etc.

So, on my own I tried it with airplane mode on & using Wi-Fi calling, this is the only way I can make calls now. As soon as I turn the airplane mode off and it goes back to normal, I get the call failed anytime I try.

Does anyone know what is wrong? Is it a phone issue or carrier issue? Anything I can do not to have to use airplane mode & Wi-Fi calling?

All other phones in my home are working just fine also.

Thank you!

Thank you! I didn’t know if it would be phone or carrier since every other iPhone in my house is working like normal with no issues calling or receiving calls.

I tried all the things you mentioned doing and unfortunately none have worked.

his seems like your carrier issue, Contact your Carrier (Cellular Service Provider) The agency who issued the SIM to you.

Call Failed or Dropped Calls / Disconnecting

In telecommunications, a dropped-call / Auto Disconnecting Calls / Call-Failed Muted conversation are mainly due to technical reasons / fault at the carrier's end. At times the calls are cut off before the speaking parties had finished their conversation and before one of them had hung up (dropped calls or Call Failed or Auto Disconnection or muted calls).

Few Reasons Your device Keeps Muting / Dropping / Disconnecting Calls or encounter Call Failed.

Your Signal Is Weak.
It's Raining (Cats & Dog)
The Cell Tower Is Overloaded / Heavy Traffic (Telecommunication)
You've Misunderstood Your Signal Strength
You are moving and the signal weakens while changing from one tower to another

Options Are...

Turn on Airplane mode, wait for 10-15 secs and turn off airplane mode.
Restart your iPhone (Restart your iPhone, iPad, or iPod touch - Apple Support)
Force Restart your iPhone )Force restart iPhone - Apple Support)
Check you Battery health
Take the SIM out and Put it back again
Change you SIM, if it is damaged
Time to contact your Carrier again / Change if required

WiFi Call is a Carrier Specific feature. Contact your Carrier (Cellular Service Provider), the agency that issued the SIM / eSIM to you.
