Your iPhone 7 Plus isn't receiving calls and you're starting to get frustrated. Most people (myself included) can't afford to be missing calls all day, as our iPhone is our primary number for both business and our personal lives. In this article, I'll explain why your iPhone 7 Plus goes straight to voicemail and show you how to fix the problem using a step-by-step guide.

Is My iPhone 7 Plus Broken? Why Won't It Work?

At this point, we can't be certain the exact reason why your iPhone 7 Plus goes straight to voicemail. However, we can be almost entirely certain that the issue is not hardware related.

When your iPhone 7 Plus doesn't receive calls, it usually means that you accidentally turned on Airplane Mode or Do Not Disturb, or there's a connectivity issue with your wireless carrier's network.

The troubleshooting guide below will help you fix the problem, so you won't miss anymore important phone calls.

Some potential issues include having poor service or your iPhone going straight to voicemail anytime you receive a call.

  1. Make sure that your iPhone is connected to a Wi-Fi network, or that Cellular Data is turned on.

  3. Make Tap General.
  4. Tap About.
  5. After a few seconds, if a carrier settings update is available, you'll see a pop-up on the screen of your iPhone which says, "New settings are available. Would you like to update them now?"
  6. Tap Update.

DFU Restore Your iPhone

A DFU restore has the potential to fix software problems by completely erasing the code which may be causing your problem. The code is rewritten as if  your iPhone is brand new, so the software problem may get solved.

Think of it like a house that has cracks in the foundation. Rather than try and fix the cracks, we are building an entirely new foundation.

If you can, back up your iPhone before completing a DFU restore. Any time you do a restore, it erases everything from your iPhone. However, after the restore is completed, you restore all your backed up data back onto your iPhone.

How Do I DFU Restore My iPhone?

Watch our DFU restore video walkthrough on YouTube, or follow the steps below:

  1. Using a Lightning cable, plug your iPhone into a USB port on your computer.
  2. Open iTunes. It doesn’t matter if your iPhone is on or off.
  3. On an iPhone 6s or older, press and hold the Home button and the power button. On an iPhone 7, press and hold the power and volume down button.  
  4. After 8 seconds, release the Power Button, but continue to hold the power button (iPhone 6s or older) the volume down button (iPhone 7).
  5. Let go of the power button or volume down button when iTunes says “iTunes has detected an iPhone in recovery mode.”
  6. Your iPhone’s display will be completely black if you’ve successfully entered DFU mode. If it’s not, try again from the beginning.
  7. Restore your iPhone using iTunes.
