My incoming calls are going straight to voicemail, iPhone

Hi and Welcome to JustAnswer.com! My Name is ***** ***** I look forward to assisting you today with your question. I’m sorry to hear you're having trouble. I know that can be frustrating. Hopefully, we can get this resolved quickly. I understand that you are facing an issue with your iPhone. Please give me a few minutes to review and answer your question. Thanks for your patience.

Are you able to make calls from your iPhone?

Thank you. I will send the instructions here now. Give me a few minutes, please.

We can soft-reset it and see if it works. Please follow the steps below;

1. Quickly press and release the volume up button.

2. Quickly press and release the volume down button.

3. Press and hold the side button continuously for 10-15 seconds or until it shows the Apple logo (max of 20 seconds).

Important, please read: It may take up to 10 or more seconds to show the Apple logo, so keep holding down the side button and ignore the "slide to turn off" message if you see it (don't attempt to slide to turn it off). Please do the steps again if it doesn't work on the first try and make sure you do it exactly. Timing is important. Don't hold down the Volume buttons. Quickly press and release buttons. Only hold down the side button at last for 10 seconds. There shouldn't be any delay between the presses.

​​​​​​​Check if it works now. Please let me know if that didn't work, so I will continue to help you.

Timing is important when you do the steps. Please repeat the steps again and when you do it correctly, it will show the Apple logo.

I'm sorry for the difficulty.  Please see this video --> https://www.youtube.com/watch?v=RfU_7w5487Y

(Instructions are applicable to all 13 series)

Go to Settings > Focus > Do not Disturb (or Settings > Do Not Disturb if using an older iOS version) and make sure it is not turned on there.

Then open Settings > Phone and make sure the "Silence Unknown Callers" option is disabled.

When you reset it, did it show the Apple logo?

That means you did it correctly. We can reset the network settings of your iPhone.

On your iPhone, go to Settings > General > Transfer and Reset > Reset and tap Reset Network Settings. This will not delete anything from your iPhone. It just resets some settings like WiFi, Cellular, etc.

(Reconnected to your WiFi network as well since this will disconnect the WiFi)

Please check if it works now.

Unfortunately, this seems to be an issue with your SIM card or your account (even if you can make calls or use cellular internet). We have already tried all possible troubleshooting steps so far. I'm afraid you will need to take it to your service provider store or carrier network store and have them check your account or issue a replacement SIM card (with your same number and plan). I'm sorry I couldn't solve the issue for you. If you have any questions or would like any additional information, please don't hesitate to ask.  Have a good day!
