Why Does My iPhone Say No Service?

Why does your iPhone say no service? One possible reason is the failure to pay the bill on time. However, if this is not the case for you, the iPhone no service issue may be related to the carrier, device settings, or the system. Specifically, common scenarios include:

  • Airplane mode is enabled during travel;
  • You are not in the service area of your carrier;
  • Your carrier's network problems remain unresolved;
  • iOS system updates have changed some settings;
  • App's bugs and defaults impact mobile service;
  • No service on a new iPhone may be because the SIM card is not activated or the selected carrier plan is terminated.

Although the causes may seem diverse and varied, they are all easily fixable. The following eight solutions are tailored to address each specific issue. Now, scroll down and help your iPhone get out of the no service problem.

1. Toggle Airplane Mode

Whether you've left airplane mode on or connected to a service with no success, toggling airplane mode is the quickest and most effective way to solve the no service on iPhone. It is advisable to try this in urban areas or places with strong signals, and here is how it works.

Step 1. Open "Control Center."

  • For iPhone X and newer: swipe down the screen from the upper right corner;
  • For iPhone 8 Plus and older: swipe upward the screen from bottom to top;

Step 2. If the "Airplane" icon is orange, just tap it to turn it off. Or instead, you can keep it on for a while, and then disable it. This can help your iPhone re-establish a connection with the carrier network

Toggle Airplane Mode

💡 Tip:

You can also find and toggle "Airplane Mode" from the "Settings" app.

2. Turn On and Off the Cellular Again

At times, even when the iPhone shows "no service," you can still make calls and send messages, but the cellular network may be undesirable. In such cases, attempt to re-enable Cellular Data in Settings, which has a similar effect to the first method above. To try this, you also need to ensure you're in an area with cellular network coverage, then refer to the steps below.

Step 1. Open the "Settings" app and find "Cellular' or "Mobile Data";

Step 2. Turn off the "Cellular Data" switch, and then turn it on again;

Step 3. If you want to improve the speed of cellular, go to "Cellular Data Options" and choose 4G or 5G.

Turn on Cellular Data

3. Check the Coverage Area

The first two solutions to address no service on iPhone are more effective within specific coverage areas. This is because certain carrier networks have limited coverage in specific areas. In remote areas, forests, or underground locations, carrier networks may either have limited or no coverage, leading to your iPhone saying no service. To overcome this issue, try to move closer to populated areas such as cities or villages, where your device can regain a signal.

However, if you encounter this problem in a city center, it may be due to interference caused by tall buildings and a dense population. At this time, it is suggested to move towards higher floors of buildings or walk a few miles away from your current blocks.

💡 Note:

When you enter a coverage area, promptly toggle Airplane Mode or re-enable Cellular Data, as both allow you to visually check whether the service has been restored.

4. Switch Cellular Data Options

Not only iPhones but many smartphones no longer support 3G cellular networks. This is primarily owing to the gradual phasing out of old 3G technology by major carriers like AT&T. If you are still using a 3G network on your iPhone, therefore, you are likely to see iPhone says no service. A simple resolution is to reach out to your carrier to upgrade your plan and switch the cellular data option on your iPhone. Here is how it works.

Step 1. Launch "Settings" on your iPhone. Then go to "Cellular" (or "Mobile Data");

Step 2. Locate "Cellular Data Options" from "Cellular Data";

Step 3. Enter the interface of "Voice & Data" and select "4G" or "5G". For always 5G, choose "5G Auto" instead.

5. Update Carrier Settings

The iPhone no service problem is closely linked to cellular network performance. Besides updating your carrier plan as mentioned earlier, you can also attempt to manually update Carrier settings on your iPhone. Usually, carrier updates happen behind the scenes, and these updated settings not only protect against malicious software threats but also introduce new features to improve speed, performance, and connectivity. For a specific update process, refer to the steps below.

Step 1. Make sure your device connects to Wi-Fi or a mobile hotspot;

Step 2. Open Settings and head to "General" > "About";

💡 Note:

6. Reset Network Settings

If the above methods to enhance cellular network connectivity and performance don't solve no service on your iPhone, you need to reset network settings. This method will restore all network settings to default. On this basis, it will address underlying network configurations and help you retrieve signal reception.

However, it's important to be aware that network resetting will erase all saved Wi-Fi passwords, VPN, APN settings, and even carrier information. If you have backups for these, follow the steps below to reset network settings on your iPhone.

Step 1. Open the Settings app on your device;

Step 2. Navigate to "General" > "Transfer or Reset iPhone", and tap "Reset";

Step 3. Choose "Reset Network Settings" from all options and enter your passcode to confirm the process.

FAQs of How to Fix No Service on iPhone

Why does my iPhone say no service but I have WiFi?

WiFi and cellular networks are distinct. WiFi connects through a wireless router, while cellular data uses the carrier's network to provide internet and other mobile services. Therefore, they do not directly affect each other. However, when you see your iPhone says no service, you should determine whether cellular data is not enabled or if there is an issue with it. If it's the latter, you need to check the methods in this article or promptly contact your carrier for resolution.

Why does my iPhone say no SIM card?

The display of no SIM card on the iPhone is likely due to the SIM card being loose or improperly placed. To resolve this issue, you need to use a paper clip or a SIM-eject tool to remove the SIM card and then reinsert it correctly into the tray. However, another possible reason is a damaged SIM card, in which case you'll need to contact your carrier to replace the SIM card. It's important to note that when inserting a new SIM card into the iPhone, remember to go to the Settings app and update Carrier settings. Skipping this step may result in your iPhone having no service.


So if you encounter the iPhone no service issue, there are 8 methods available. The first seven methods focus on the iPhone restart or setting adjustment to address no service on your iPhone.
