Updated June 14, 2019 If your iPhone has no service, either because you see an error message or you find you can’t make or receive phone calls, there are several potential issues. You might have service issues like a problem with your cell phone carrier’s service plan, a hardware issue with your phone, or a misconfigured setting. Why Does My iPhone Say "No Service" Since there isn’t one single problem that might be causing your iPhone to report it has no service, we'll need to troubleshoot the issue, trying the easiest and most likely solutions first. Your lack of service might be caused by a simple setting change, like your iPhone is in Airplane Mode or your cellular settings might be set incorrectly. In less common cases, your iPhone might need to have its cellular settings updated via a software update from your cellular service provider, or you might need to reset or replace the SIM card. And it’s always possible there's a problem with your cellular service plan, requiring a call to your cell phone carrier to resolve the issue. How to Fix Your Phone When It Has No Service Before we attempt to change any iPhone settings or perform more time-consuming troubleshooting tasks, there are a few simple things you can do that might quickly resolve the problem. If those don't solve your problem, we'll move on to more advanced potential fixes. Make sure that your phone is not accidentally set to Airplane Mode. Airplane Mode disables cellular and Wi-Fi service. Your phone is in Airplane Mode if you see an airplane icon at the top right of the iPhone screen, where the signal strength bars ordinarily appear. Toggle Airplane Mode off and then on again. Sometimes, especially when you are on the edge of a service area or you have lost service and should be back in service, switching your cellular service off and on again is all it takes to fix the problem. Make sure you’re within your cellular coverage area. If you're deep inside a building, underground, or outside an urban area, it might simply be you have no service in that location. Check for signal strength bars at the top right of the screen. Restart your phone. Like toggling Airplane Mode, completely restarting your iPhone might “wake” your cellular service and return it to operation. Turn on Wi-Fi Calling if you have poor service. If you find that you regularly have poor service or no service somewhere that you spend a lot of time, such as your home, you can enable Wi-Fi calling on your iPhone. This is a great solution if you move to as new house or apartment and find it’s in a cellular dead zone for your wireless provider. If you live in a cellular dead zone, you might consider purchasing a signal booster for your home, which amplifies your cellular signal so you can use your iPhone normally. Signal boosters are available directly from most cellular providers and at retail. Check for a carrier settings update. Carriers occasionally release updates which affect your ability to connect to the cellular network. It’s possible your service might be affected by a new update you've to install on your iPhone. Reset your network settings. It’s possible that your iPhone’s settings have been corrupted in a way that’s preventing you from getting cellular service. You can reset it back to the factory conditions. Verify your cellular settings. If you still have no service, there is one other set of software settings you can check. Tap Settings > Cellular and ensure Cellular Data is on. If it's already on, toggle it off and back on. Remove and replace your SIM card. It’s possible your SIM card is not working properly, either because it isn’t seated properly or it might be damaged. Inspect it for damage and gently clean it by blowing on it or wiping it with a cotton swab or cloth, then replace it. Check with your carrier. If you still have no service, contact your cellular service provider and ask about any local outages, problems with your service plan, and if your device is being blocked.
