Part 1. Troubleshoot iPhone Not Receiving Calls

#1 Move to an Area with a Good Signal

The most common situation where you can't receive calls on your iPhone is a bad signal. Since iPhone is a well-known electronic for its bad signal, this problem comes up from time to time. If you are a new iPhone user, keep in mind that move to an area with a good signal when you see the message No Service appears on the status bar.

#2 Enable and Disable Airplane Mode

If the No Service remains, or you have already stood in a place with a signal, but the iPhone not receiving calls issue doesn't disappear, you need to check whether the Airplane Mode is on. If it is, the culprit is obvious. So, you need to turn it off to troubleshoot if your iPhone is able to receive calls. If it is not, you can try to enable the feature and wait for seconds to disable it. This action will freshen the signals and network to some extent.

#3 Turn Off iPhone

Why is my iPhone not receiving calls? Whether you know the real reason, the simplest and the most direct method is to restart your iPhone. You can check the status of your SIM card while your iPhone is in the shut-down state. After that, you are able to turn on your iPhone. Below are the detailed steps to restart iPhones with different models.

  • iPhone X, 11, 12, 13, and later: press and hold the Side button and the Volume Up button or the Volume Down button → drag the power-off slider to turn off→ turn on by pressing and holding the Side button
  • iPhone 6, 7, 8, or SE (2nd or 3rd generation): press and hold the Side button for a while→ turn off by dragging the power-off bar → turn on by pressing and holding the Side button until the Apple logo appears
  • iPhone SE (1st generation), 5, or earlier: keep pressing and holding the Top button → drag the slider to turn off → enable iPhone by pressing and holding the Top button

#4 Reinstall SIM Card

The reason why your iPhone is unable to receive calls might be your incorrect installation. On the other hand, the new iOS system may impact the SIM card system on your iPhone, which could potentially damage the running of phone calls. In this case, you need to remove your SIM card and give your iPhone a cushion against the effects of the iOS upgrade. Therefore, when you complete the previous step - turn your iPhone off, you can remove and check your SIM card.

  • Step 1: Plug the ejector into the hole beside the SIM card slot. The tray is on the left side if you are using iPhone 12 and later while it is on the right side on other iPhone models.
  • Step 2: Push the SIM-eject tool towards your SIM tray and take it out of your SIM card.
  • Step 3: Check if there are any scratches or strain on the surface of your SIM card. If it looks fine, place it into the slot in terms of the notch.
  • Step 4: Insert the SIM tray into your iPhone from the correct orientation.
  • Step 5: Turn on your iPhone to see if your problem is resolved.

#5 Check Settings on iPhone

The main reasons for not receiving calls on iPhone are related to the settings you make wrongly. In this section, ways to check 4 features are provided. It is necessary for you to go ahead examining one by one.

  • If there is no ringtone to remind you or you can't hear the incoming calls, you'd better check the sound settings on your iPhone. First, check whether the physical Mute button on your iPhone's left corner is on. If it makes your iPhone into Silent mode, turn it off. Then, go to Settings and tap Sound & Haptics. On this interface, you'd better check all the features of your phone calls carefully.

  • If the notifications for your phone calls are not enabled, it is certain that you can't receive calls. To check this option, head to Settings, tap Notifications and scroll down to Phone. Here you need to ensure that the Allow Notifications toggle is on in all alerts.

  • If you enabled the Do Not Disturb function, it will absolutely intercept incoming calls. Navigate to Focus and switch Do Not Disturb off, or you can directly turn it off on the control center. Meanwhile, if the Share Across Devices option is on, you need to turn off the toggle to avoid all calls coming to your other devices. By the way, check the Sleep option on the Focus. Enter Sleep and examine the Turn on at Bedtime is disabled.

  • Proceed to Settings and enter Phone. From this feature, it's essential to troubleshoot Blocked Contacts, Silence Unknown Callers, Call Forwarding, and Voice & Data in Cellular Data Options. Check Blocked Contacts, because the not receiving phone numbers may be in it. Hence, you need to remove it. Check Silence Unknown Callers to see if the unknown calls are blocked. Check if the Call Forwarding is activated, and make sure the incoming calls won't be routed. Last, go to Cellular, enter Cellular Data Options and tap Voice & Data. Then toggle VoLTE off.
