iPhone 14Pro - Problems with call answering

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

Call Failed Call Muted 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 / Change if required

Check your iPhone settings

Go to Settings and turn on Airplane Mode, wait five seconds, then turn it off. Check Do Not Disturb. Go to Settings > Focus > Do Not Disturb and make sure it's turned off. Check for any blocked phone numbers.

HI,

I have exactly same problems with my new iPhone 13.

I had iPhone 11 and used it in same place with no problems, but now when I changed my phone problems appeared.

I try to answer the call on the iPhone, it does not work. The call is answered but a connection is not established.

When I then end the call and try to call the caller myself, it doesn't work the first time, but only the second time.

Same happens when I try to call somebody, it is ringing but after 2-3 tones it mutes and stops ringing without shutting the call.

This happens almost every time and I need to ring twice or tree times until the call goes to the receiver.

This is very annoying and new phone should not have these issues!

Same place, same SIM as in my last iPhone so this in no network or other problem, problem is in this iPhone.

What should I do?
