My iPhone Says No Service. Here’s The Real Fix!

If your iPhone says “No Service”, you can’t make or receive phone calls, send text messages, or connect 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 work. In this article, I’ll explain why your iPhone says No Service and show you exactly how to fix the problem.

Why Does My iPhone Say No Service?

Your iPhone may be saying No Service because of a software problem, a hardware problem, or an issue with your cell phone plan. Unfortunately, no one-size-fits-all solution to this problem, so I’ll walk you step-by-step through the troubleshooting steps I found most effective when I worked at Apple.

If you’re on top of a mountain, you may wish to return to society before you continue. If you’re not, let’s stop your iPhone from saying No Service for good.

1. Check In With Your Carrier About Your Account

Carriers cancel customers’ accounts for all sorts of reasons. I’ve heard of cases where iPhones were disconnected because the carrier suspected fraudulent activity, the customer’s payment was late, and about disgruntled spouses who really didn’t want to hear from their ex.

If any of these reasons resonate with you, give your carrier a call, just to make sure everything’s OK. Your iPhone will say No Service if your account was cancelled, and this is a common, yet easily-overlooked reason for this problem.

If you discover the No Service problem is being caused by your carrier, check out my cell phone plan comparison tool to learn how you could save hundreds of dollars a year by switching things up. If it’s not your carrier’s fault (and most of the time this problem isn’t), it’s time to take a look at your iPhone’s software.

2. Update Your iPhone’s Software and Carrier Settings

A lot of people’s iPhones said No Service after Apple released iOS 8. Although that problem has long since been resolved, iOS updates always contain a slew of fixes for less-common software bugs that can cause the No Service problem. You can proceed in one of two ways:

  • If you can connect to Wi-Fi, you can check if a software update for your iPhone is available by going to Settings -> General -> Software Update.
  • If an iOS update isn’t available, go to Settings -> General -> About to check for a carrier settings update. There isn’t a button to check for these updates — just stay on the About page for 10 seconds or so, and if nothing pops up, your carrier settings are up to date.
  • If you don’t have access to Wi-Fi, connect your iPhone to your computer and use iTunes to check if a software update is available for your iPhone. If an update is available, iTunes will automatically ask if you’d like to update your iPhone. iTunes also checks for carrier settings updates automatically, so if it asks, it’s a good idea to update that too.

If your iPhone says No Service after you’ve updated your software, or if your software is already up-to-date, it’s time to dive in and do some troubleshooting.

3. Reset Network Settings

Resetting your iPhone’s network settings to factory defaults can fix all sorts of cellular and Wi-Fi related problems on your iPhone. This “forgets” all your Wi-Fi networks, so you’ll have to reconnect to them and re-enter your Wi-Fi passwords. The No Service problem may disappear after your iPhone reboots.

To Reset Network Settings, open Settings -> General -> Reset -> Reset Network Settings. Enter your iPhone passcode, then tap on Reset Network Settings when the confirmation pop-up appears near the bottom of your iPhone’s display.

4. Check Cellular Settings On Your iPhone

There are a number of cellular data settings on your iPhone, and if something isn’t set up correctly, your iPhone might say No service. Settings can get changed accidentally, and sometimes the problem can be fixed simply by turning a setting off and back on.

The problem with diagnosing cellular settings on your iPhone is that what you see in Settings -> Cellular varies from carrier to carrier. If you don’t see a setting I mention in this section, move on to the next suggestion — you’re not missing anything. Here are my suggestions:

  • Go to Settings -> Cellular, and make sure Cellular Data is on. If it is, try turning it off and back on again.
  • Go to Cellular Data Options -> Roaming and make sure Voice Roaming is turned on. Voice Roaming should be on for most people in the United States. Carriers don’t charge for cellular roaming like they used to. If you’re interested, one of our writers wrote an article 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 when you’re traveling internationally to avoid a massive phone bill when you come home.
  • Go to Settings -> Carriers and turn off automatic carrier selection. Your iPhone may stop saying No Service if you manually choose which cellular network to connect to. A lot of readers will not see this option on their iPhones, and that’s perfectly normal. It only applies to certain carriers.

5. Take Out Your SIM Card

Your iPhone’s SIM card links your iPhone to your carrier’s cellular network. It’s how your carrier distinguishes your iPhone from all the others. Sometimes, your iPhone will stop saying No Service simply by removing your SIM card from your iPhone and putting it back in again.

If you’re not sure how to remove your SIM card, read steps 1-3 of my article about why iPhones sometimes say “No SIM.” To remove your SIM card, you can pick up a SIM card ejector tool on Amazon — or just use a paper clip.

If your iPhone says No Service after you read my other article, come back here and move on to the next step.

6. Check For Water Damage

It’s easy to understand why an iPhone might say “No Service” if it’s smashed, but water damage can be invisible and insidious. If your iPhone started to say “No Service” after it got wet, there’s a good chance that water damage is causing the problem.

Apple doesn’t repair water-damaged iPhones — they replace them. If you have AppleCare+, the cost of replacing a damaged iPhone is negligible compared to what it costs if you don’t. If you’re looking for a less-expensive alternative, check the Repair Options section below.

7. Back Up And Restore Your iPhone, But Read The Warning First!

Software corruption can cause everything from excessive battery drain to iPhones getting too hot to problems like this one. Make sure you back up your iPhone to iTunes or iCloud if you choose to continue, because restoring your iPhone erases everything on it.

An Extremely Important Warning

Restoring your iPhone when it can’t connect to a cellular network is very dangerous, for this reason: An iPhone has to be activated before it can be used after a restore. If you restore your iPhone and it still says No Service, it will be totally unusable. You won’t be able to do anything: not restore your iPhone, not use your apps; nothing.

If you have a backup phone available and you’re willing to take the risk, restoring your iPhone can resolve this issue, but there are no guarantees. I don’t recommend you try to restore your iPhone unless you have an Apple Store nearby.

8. Contact Your Carrier Or Repair Your iPhone

Sometimes carriers have special activation codes that can resolve the problem when your iPhone says No Service. These codes change too frequently and there are too many carriers to list specific codes here, but there’s a chance your carrier may be able to help you over the phone. If that doesn’t work, your carrier will send you to an Apple Store to have your iPhone diagnosed by a technician.

Repair Options

If you choose to go to an Apple Store, it’s a really good idea to call ahead or go online to make an appointment at the Genius Bar before you arrive. You could end up standing around for a while (or buying a new Mac) if you don’t.

Tips And Alternate Solutions

One of the biggest side effects when your iPhone says No Service is that its battery begins to die very quickly. If that’s happening to you (or if you’d like to get better battery life in general), my article about how to save iPhone battery life can make a world of difference.

No Service? No More.

20 years ago, a complaint about our inability to make phone calls from wherever we are might be seen as a “luxury problem”, but things have changed, and our ability to stay connected is vitally important to our daily lives. In this article, you learned why your iPhone says No Service and exactly how to fix it. I’m interested to hear which fix solved the No Service problem for you in the comments section below.

My iPhone 5s is having no service problem, sometimes I have service for few minutes then it takes it off for hours. I’ve tried different network provider but still the same problem. I’ve done most of the options but the problem persists. Right now I’ve service but I’m very sure it won’t last 30 minutes.. Any other solution ?

Hi, it’s Brenda again (see comment below from 4 months ago). THAT phone that I wrote about…well, about 30 days later, it suddenly totally lost any ability to connect to any cellular network whatsoever. I tried everything, including restoring it to factory specs. Nothing worked. The SIM card worked flawlessly in my old iPhone 5. Apple came up with the idea that since the replacement phone they gave me came from a U.S. Apple store and my cellular network is in Canada, that was the problem. It did work for about a month in Canada on my carrier’s network, though.… Read more »

Hello, I have and iPhone 6 that shows no service and will still not have after all these options (ideas) I’ve tried it all and still not functional so could it be that my antenna would be no functionable anymore which is the complete back housing of its phone or what recommended to do besides bringing it back to Apple??? Thanks..

Reset network settings worked for me. Amazing. I was about to solder in a new sim card tray. Thanks a bunch!

Nopes, Nada, nothing has worked for me. Resetting the phone worked temporarily, resetting the network settings worked temporarily but the problem of “No services” resurfaces within hours, let alone days. Just upgraded my device OS to 9.3.2. Finished updating the software a few mins back and sitting with “No Service” again.

I have an iphone 4 and it suddenly said no signal in the middle of the day. I was stuck with it like that until I got home. I reset the network settings and as soon as it turned back on it worked! Thanks so much

I have tried all of these troubleshooting options except restore, and nothing has worked. I have an iPhone 6 (new as of February, replaced by AppleCare after another one bit the dust) which was working for several months without any problems. In the middle of the night last night my phone buzzed, prompting me to “activate phone”. After doing this I’ve had no service. On the phone with my carrier four times today, no luck. What’s going on??

I just had my first iPhone 6 replaced under warranty after a few months because the wifi and bluetooth finally completely quit after several weeks of fighting with it. Now after 2 days with the new phone, I woke up this morning to “no service”. I tried going to carrier and turning off the auto, which resulted in the phone just endlessly “searching”. It could ‘see’ the networks, but it would not connect to any of them. Spouse’s phone had 4 dots. I restarted, which resulted in my losing the “carrier” settings completely. I toggled the airplane mode on and… Read more »

Nothing worked. Interesting that the iPhone says 9.3 is available, but when I connect to the Mac and check for updates, it says that 9.2.1 is current and no updates are available. It seems to me that verifies what I read on Mac Rumors that Apple has pulled the update and are working to fix it. Otherwise, I would expect iTunes to find the update. Here’s my work around: I went to the App store and downloaded the basic Google browser. Voila! Super fast Internet searches. Works perfectly. BTW, I have a 5S.

Turn your phone off and remove SIM card, and reinsert SIM card and turn phone back on and it should work. Atleast it did on my iphone6plus.

This happened on my first 6 about two months after I got it. after an arduous process with Apple tech support, I got it replaced. That phone’s battery started to die after about 6 months, so once again I got a replacement via Apple. Now, about three months later, that replacement has stopped connecting to the cell network as well, which is why I’m here today. I never had any of these issues with any of the prior generation iPhones and I’ve owned some version since 2007. Not sure if i’m just unlucky or if the 6 is just a… Read more »

Hello,

I have been have this issue with my iPhone 6 for a few weeks now. It happens occasionally, but recently it has been occurring daily. Usually, resetting the phone few times got it to work, but that’s the only solution I found. I am strongly considering taking it to my local Verizon store to have it replaced, as the touchscreen also acts up and does not recognize touch input sometimes. I feel like water damage caused these events, but I do not remember getting my phone wet at all. Any input would be greatly appreciated.

Thanks,

Nick
