How can I fix no dial tone when making calls on iPhone 16 Pro Max?

Since the latest update to 18.3. When I now make calls or FaceTime it does NOT make the dial tone. it’s very confusing cause I’m just unsure if it’s ringing until the other end is answered.


I know this also not only happening to me and a few of my friends. Is there a new setting? I can’t seem to figure it out.

Hi Lawrence,


Could you clarify what you mean by “if you aren’t hearing it, the remote network is not sending it”? Are you saying the carrier or network connection is responsible for the ringing?


For more context, the call is going through, and someone answers on the other end every time. However, on my end, it seems like the call isn’t ringing at all, even though it actually is.


I appreciate your help with this!

-Thanks!

Going back to copper wire landline, when you made a call you wouldn’t hear the ring sound until all of the switches closed between your line and the switch for the number you called, and it meant that the connection was successful, and sometimes there would be a delay, as there were a finite number of wires and switches.


With cell phones, it isn’t that different; when you make a call the switch for the receiving end has to find the mobile phone you called; it could be anywhere in the world. It has a hint, because cell phones periodically contact the network and say “here I am”, so the called carrier first tries the tower that received the most recent “ping”, then tries towers around that one moving further out until it actually finds the phone. Until it finds the phone you hear silence; when it connects you will hear a ring sound sent by the called network switch. But if the called user answers immediately you won’t hear the ring.

The ring tone is different from a dial tone. I’m not sure if you’re just interchanging the names or exactly which is giving you issues.


But in either case, when I have no ring tone, I’ve called my carrier, AT&T and they’ve reset something on their end and they tell me to restart my iPhone and it’s fixed.


Have you contacted the support team at your carrier?

The ring sidetone is sent by the network of the person you are calling; it isn’t generated on your phone or even by your carrier. Many carriers have stopped sending it.


As I already posted in this thread:

But that’s the thing, the people that I’m calling aren’t answering quickly at all. It’s just a lot of silence( which makes me believe my signal is failing) and then poof, you either hear a voice or a voicemail. But nothing indicating the call successfully connected.
