MAY 30, 2017

Your iPhone 7 says "No Service" and you don't know why. This problem is incredibly frustrating because you can't make calls or receive texts, unless you have a connection to Wi-Fi. In this article, I'll explain why your iPhone 7 says no service and show you how to fix the problem so you can make and receive calls and text messages once again.

First, Try Removing Your SIM Card

Before we get into the troubleshooting guide, try removing your SIM card, then putting it back into place. A SIM card is what connects your iPhone 7 to your carrier's wireless network, so taking it out, then putting it back can sometimes fix an iPhone 7 that says no service.

This guide will show you how to remove your SIM card from your iPhone. If you try this step and nothing changes, keep reading!

If My iPhone 7 Says No Service, Does That Mean It's Broken?

At this point, it's uncertain why your iPhone 7 says no service. However, many times the issue is the result of a software problem, and there may actually be nothing physically wrong with your iPhone 7. Make sure you work through each troubleshooting step below before visiting your local Apple Store or reaching out to a third-party repair service!

How To Fix An iPhone 7 That Says No Service

6 Steps Total
1.

Update Carrier Settings

The UpPhone recommend that you update carrier settings immediately after they become available because outdated settings may lead to connectivity issues between your iPhone and your wireless carrier's network.

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.
  2. Open the Settings app.
  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.

Update Your iPhone Software In iTunes

You can use iTunes to perform iOS updates on your iPhone. If you're unable to update your iPhone in the Settings app, sometimes using iTunes to update your iPhone is a simple workaround.

How Do I Update My iPhone Software In iTunes?

  1. Plug your iPhone into your computer using a Lightning cable (charging cable).
  2. Open iTunes.
  3. In the upper left hand corner of iTunes, click the iPhone icon. iPhone icon in itunes

3.

Reset Network Settings

When your iPhone connects to a Wi-Fi or Bluetooth device for the first time, it saves information about how to connect to that network or device. If something changes with that process, it may cause connectivity issues.

Deep software problems, especially with network settings, can be difficult to track down. Rather than trying to track an issue down, we're going to reset all network settings and give your iPhone a fresh start.

How Do I Reset Network Settings?

  1. Open the Settings app.
  2. Tap General.
  3. Scroll down and tap Transfer Or Reset iPhone.
  4. Tap Reset.
  5. Tap Reset Network Settings.
  6. Enter your passcode if prompted.
  7. Your iPhone will shut down, reset, and turn itself on again when the reset is complete.

Contact Your Wireless Carrier

Sometimes when your iPhone experiences issues related to your cellular network (no or poor service, calls going straight to voicemail), the problem is stemming from the cellular network, not the iPhone itself.

  1. Verizon: 1-(800)-922-0204
  2. Sprint: 1-(888)-211-4727

Repair Your iPhone With Apple

Apple repairs iPhones at the Genius Bar in Apple Stores and through their online mail-in repair service. Apple repairs are high-quality, but out-of-warranty repairs can be much more expensive than third-party solutions. If you're looking to save some money you're not covered by Apple's warranty, you may want to check out our other recommendations.

How Do I Repair My iPhone With Apple?

How To Repair Your iPhone With Apple's Mail-In Service

  1. Visit Apple's support website to begin the online mail-in repair process.
  2. Alternatively, call 1-800-MY-APPLE (1-800-692-7753) to set up a repair.

How To Repair Your iPhone At The Genius Bar Inside Your Local Apple Store

  1. Visit Apple's website to make a Genius Bar appointment before you go into the store. Apple Stores are extremely busy, and if you don't have an appointment, you may have to wait for hours or end up being turned away. (Editor's note: I'm a former Apple tech and we're not exaggerating — please, do yourself a favor and make an appointment first!)
  2. When you arrive, go to the Genius Bar to check in for your appointment.
  3. Genius Bar appointments always include free diagnosis. If you're under warranty, many repairs can be done on the spot, but it all depends upon which parts are in stock. If you're not under warranty, the Genius will give you a quote for the cost of a repair.
