9 Ways to Fix No Service on iPhone 15 and 15 Plus

Fixing an iPhone 15 or 15 Plus showing “No Service” is not complicated as long as there’s no problem on your carrier’s end. You just have to follow the right steps to get the signals back. So, without further delay, let’s begin our troubleshooting.

1. Toggle Airplane Mode on and off

As mentioned earlier, enabling the Airplane mode temporarily deactivates the SIM card and all related services. So, you must ensure that it is disabled on your iPhone.

You can toggle off the Airplane mode via Settings or Control Center.

If the Airplane mode is already disabled, turn it on and off. It will refresh wireless connections and could restore lost cellular signals.

2. Restart Your iPhone

Restarting the device is a common and effective remedy to fix many issues on your iPhone. It can also resolve minor glitches that could trigger network problems. Restarting an iPhone also means the device will try to establish a connection with your nearest cellular tower again.

To restart your iPhone 15 or 15 Plus, press and hold the side and volume buttons until you see a slider. Then, drag the slider to power off your iPhone. Hold the side button until you see the Apple logo on your screen.

If restarting your iPhone does not help, check for pending carrier updates (more on that in the next solution).

3. Check for Carrier Settings Update

Your carrier may have released an update that could address existing problems and improve the connection. You must check for pending carrier updates and install them (if available).

  1. Connect your phone to a Wi-Fi network.
  2. Tap on the Settings app.
  3. Select General and click About.

If a carrier update is available, a pop-up should appear for the same. Click Update to download and install it.

4. Re-insert Your SIM Card

Your SIM card may not be seated properly, causing No Service on your iPhone 15 or 15 Plus.

Ensure that the SIM card is inserted correctly. For this, turn off your iPhone and remove the SIM tray. Now, clean the SIM card and the tray using a soft cloth. Correctly place the SIM card on the SIM tray and reinsert it.

Turn on your iPhone and check if the network signals are back.

5. Update Your iPhone

Updating your iPhone is a crucial step. Not only will it add new features and improvements, but also fixes the known vulnerabilities. So, if there’s an iOS bug causing No Service on iPhones, it should be fixed via a software update.

Here’s how to update your iPhone:

  1. Ensure your iPhone is connected to the internet.
  2. Open the Settings app and tap on General.
  3. Select Software Update.

If an update is available, download and install it.

Toggling the mobile data off and on sometimes resolves network-related problems on iPhones. Try doing the same to check whether it works for you or not.

Go to the Settings app and tap on Mobile data. If your mobile data is turned on, turn it off, wait a minute, and turn it back on again.

7. Reset Network Settings

Your iPhone 15 may have misconfigured network settings, causing it to display “No Service”. Rather than going through all network settings, you can reset network settings to bring back the default settings.

Resetting the network settings removes saved Wi-Fi networks and paired Bluetooth devices. Doing this will also reset mobile data settings and APN and VPN settings. So, make sure you have the Wi-Fi password and existing APN and VPN settings noted somewhere for later usage.

  2. Click on Transfer or Reset iPhone.

9. Contact Your Carrier

If you are located within the serviceable area of your carrier but still getting no network signals, contact your carrier to check if there are technical issues or ongoing maintenance.

You can also use a third-party tool such as to check if your carrier services are affected. If so, you can’t do anything other than wait for the engineers to resolve it.


You probably wouldn’t expect a premium smartphone such as iPhone 15 or 15 Plus to run out of cellular networks. However, technical hiccups are not uncommon in the evolving world of technology. But, there are effective approaches to resolving “No Service” on iPhones, which I’ve mentioned in this guide.
