Why your phone shows a "No Service" message

If you're getting this message on your phone it means that your device cannot find a signal from your cellular carrier. This prevents you from making calls, sending texts, and other normal functions.

In this article, we'll walk you through 5 of the most common fixes for network connection issues so your phone will be back in service in no time.

1. Restart your phone

The easiest and often the most effective way to resolve a no service or signal issue on an Android or Samsung phone is to restart it. Doing so will reset any processes that may be interfering with your device's performance. Here's how:

  • Turn off your device.
  • Once the phone is off, wait 30 seconds and turn it on.
  • Check to see if this fixed the issue once it reboots.

2. Turn Airplane Mode on and off

Still having problems? Try to manually connect to your service provider. All you need to do is to turn Airplane Mode on and then back off to re-establish a connection. This resets the device in case it lost connection to a signal tower. To do so, simply pull down from the top of your Home screen to reveal Quick Settings and tap Airplane mode to turn it on, then tap it again to turn it off.

3. Manually select your network providers

It's possible that your device is having trouble finding your network, and you have to select it yourself.

Go to Settings> Connections > Mobile networks > Network operators. A list of network providers should show up. Select yours and see if this fixes your problem.

4. Double check your SIM card

Data in your Subscriber Identity Module (SIM) card gives your phone an address for a network to find it, and vice versa. It's possible you may have bumped your phone and dislodged your SIM. Here's how to check and see if yours is properly connected to your Android or Samsung device:

  • Turn off your phone.
  • Remove the SIM card using an ejector tool or paper clip, and clean up any dust particles that could be interfering with the card (Not sure how to remove it? Check out our guide.)
  • Reinsert your SIM so it fits properly.
  • Turn your device back on and check to see if this solves the issue.

5. Restore your phone to its factory settings

It's time for your last resort—restoring your phone to its factory settings, a process that clears your device of all your personal data—including apps, passwords, photos, and videos.

A factory reset corrects most software problems. But before you try this option, make sure to back up your data—if you don't, you may lose it. Once you've done so, follow the detailed steps in our guide for how to factory reset your Samsung or other Android phone.
