No Service on Samsung Galaxy S9: Troubleshooting Guide

To fix no service on Galaxy S9, simply perform network settings reset. This will eliminate network connectivity errors on your device that prevented the phone from connecting to the network. If the problem persists, we’ve compiled a few troubleshooting steps to help you try and resolve the issue.

How to Fix No Service on Galaxy S9

No service on your Galaxy S9 is when your Samsung smartphone can’t connect to your Carrier’s network. This means that you’ll be unable to place calls, send messages, or use your mobile data. You can check the strength of your network connection by looking at the small signal bars icon located in the top right of your screen. If you see a small “x” beside your network signal or simply no bars at all, then you have no service.

It’s important to distinguish before troubleshooting if the issue is with your Galaxy S9, or simply because you’re currently located in an area with no network connection. This could be anything from a concrete basement to a remote nature location out of town. If you’ve determined there is network service in the area and your Samsung Galaxy S9 is unable to connect, then read on.

As mentioned, the first thing you can try is to reset your network settings. This doesn’t erase anything off your phone, but it does disconnect you from WiFi so make sure to reconnect after this step. Here is how:

  • Go to Settings > General Management and tap on Reset. samsungs8noservice1
  • Select Reset network settings. samsungs8noservice2
  • If your smartphone doesn’t restart automatically, power it off then back on.

After you performed the above steps test your network connection once again. Sometimes this is all it takes to get your Galaxy S9 working again. Do you still have no service and are unable to place calls or text? Then let’s try to manually connect using the following steps:

  • Go into Settings > Connections > Mobile networks.
  • Tap on Network mode and switch it to WCDMA/GSM (or whatever second option you have). This is to remove LTE and see if you can connect manually without it. samsungs8noservice3
  • Then select Network Operators and tap on Search networks.samsungs8noservice4
  • The device will take a minute or two searching for any nearby networks it can connect to. Once the search is complete your Carrier should be listed, tap on your Carrier name (Verizon, T-mobile, etc) and test your network connection once more
  • If you are unable to pull up any networks when performing your search, again make sure you are in an area where you can receive network connection.
  • You can also verify if the issue is with the SIM card by placing it in a different compatible device and testing if it’s able to connect. If you experience the same issue in a different device, try replacing your SIM card or contacting your Carrier to make sure it’s properly activated.
  • If there are no issues when putting your SIM in a different device, then the problem is with your Samsung Galaxy S9 and you can try performing a factory reset (note: this erases all data in your device so make sure to backup anything you want to keep first)

If issue persists after trying all the above including a factory reset, and after testing your SIM, then this isn’t an issue you can resolve through your settings. In this case, we recommend verifying what your options are for repairing or replacing your device with your carrier or the manufacturer.
