If your iPhone says"No Service", you can not make or receive telephone calls, send text messages, or even link to the internet unless you're using Wi-Fi. It's easy to forget how integral our iPhones have become in our lives -- until they don't get the job done. In this guide, I'll explain why your iPhone states No Service and show you precisely how to repair it.

There's no one-size-fits-all remedy to this issue, so I'll walk you step-by-step throughout the troubleshooting steps I found most powerful when I worked at Apple. If you're at the top of a mountain, then you may wish to come back to society until you continue. If you're not, let us prevent your iPhone from saying No Service for great.

1. Check On Your Carrier On Your Account:

Carriers cancel clients' accounts for all kinds of factors. I have heard of cases where iPhones were disconnected because the carrier suspected fraudulent activity, the customer's payment was overdue, and about disgruntled spouses who actually didn't want to hear in their ex.

If at least one of these reasons resonate with you, give your carrier a call, simply to be sure everything's OK. Your iPhone will say No Service if your account has been cancelled, and this is a standard, yet easily-overlooked grounds for this dilemma.

If you find the No Service problem is being caused by your carrier, take a look at my cell phone savings calculator to understand how you could save hundreds of dollars per year by shifting things up. If it's not your carrier's error (and most of the time this problem isn't), it's time to take a peek at your iPhone's software.

2.Although that problem has since been resolved, iOS updates always contain a slew of fixes to less-common software bugs which can lead to the no service issue.

You can proceed in one of 2 ways:

If you can connect to Wi-Fi, you can check whether a software upgrade for your new iPhone no service  can be obtained by visiting Settings -> General -> Software Update. If an update is not available, go to Settings -> General -> Around to test for a carrier configurations update. There isn't a button to look for these upgrades -- only stay on the About page for 10 seconds or so, and when nothing pops up, your carrier settings are current. If an update is available, iTunes will ask if you want to upgrade your iPhone. ITunes also checks for carrier settings updates automatically, therefore if it asks, it is a good idea to update that too.

3. Reset Network Settings

Resetting your iPhone's network settings to factory defaults can fix all sorts of mobile and Wi-Fi relevant issues on your iPhone. This"forgets" all your Wi-Fi networks, so you are going to need to reconnect to them and re-enter your Wi-Fi passwords. The No Service problem may disappear after your iPhone reboots.

To Reset Network Preferences, start Settings -> General -> Reset -> Reset Network Settings. Enter your iPhone passcode, then tap on Reset Network Settings once the verification pop-up looks near the base of your iPhone's screen.


There are a number of cellular data settings on your own iPhone, and when something is not installed properly, your iPhone might say No service. Settings can get changed unintentionally, and sometimes the problem could be repaired by simply turning a setting off and back on.

If you don't find a setting I mention in this section, proceed to the next suggestion -- you are not missing anything. Here are my suggestions:

Go to Settings -> Mobile , and Be Sure Cellular Data is on. When it's, consider turning it off and back on again.
Proceed to Cellular Data Options -> Roaming and Be Sure Voice Roaming is turned on. Voice Roaming should be on for most people in the United States. Carriers do not charge for mobile roaming like that they used to. If you're interested, one of our authors wrote a post that explains how voice and data roaming works on your iPhone. A word of warning: It's a good idea to turn off Voice Roaming if you are traveling internationally to avoid a gigantic phone invoice when you come home. Your iPhone may quit saying No Service if you manually choose which mobile network to connect to. A good deal of readers will not see this choice on their iPhones, and that's perfectly normal. It only applies to specific carriers.
