No Service Troubleshooting On Galaxy S8 And Galaxy S8+ Plus

Every now and then, your Samsung Galaxy S8 or Galaxy S8+ Plus might display the “No Service” message on the screen. The message is crystal clear, as long as the device has no service, you won’t be able to make or receive any phone calls or text messages. In fact, emergency calls will be your only option.

By now, you’re probably wondering if this message is the same with the “Not registered on a network” error or the one that says “No Signal”. Simply put no, it’s not the same, though the results are the same – you cannot use Samsung Galaxy S8 or Galaxy S8+ Plus as you want, when you want or need.

Nevertheless, there is a common solution for all of the above. And we’ve already discussed it on one of our previous articles regarding the IMEI number restore and No Signal error fix. Read that one before you continue with the tips in today’s article. Who knows, maybe the information presented in there will solve your problem from the very beginning.


Why do you get the No Service message on Galaxy S8 and Galaxy S8+ Plus?

What this message actually means is that your phone has lost the radio signal and it can no longer communicate with the carrier’s towers from the nearby.

Why would it lose the radio signal, you ask? Well, there are instances when, because of a GPS or Wi-Fi connectivity issue, that signal will automatically turn off. But most of the times, you or someone else who recently used your smartphone might have accidentally disabled it.


How can you fix the No Service limitation on Galaxy S8 and Galaxy S8+ Plus?

In this article, we’re going to show you three different solutions for this particular problem. The first one, and the simplest at the same time, is to check the device for the Radio signal settings:

  1. Turn on your device;
  2. Access the Dial pad;
  3. Type in (*#*#4636#*#*) and wait;
  4. The Service mode should automatically launch, without you having to press any other key, not even the Send key;
  5. Under the Service mode, tap on “Device information” or “Phone information”;
  6. Select the option to run a Ping test;
  7. Look for the Turn Radio Off button and tap it;
  8. Wait for the smartphone to restart;
  9. Tap on reboot.


After the Galaxy S8 restarts, check if you got your signal back. If not, there’s another simple option you have at hand: replacing the SIM card.

SIM cards don’t last forever and they can easily deteriorate, especially if you have a habit of taking yours off every now and then. So, it could be damaged or just incorrectly inserted. If your display still shows “No Service”, insert another SIM card in it and see if anything changes.

The third solution that we promised you relates to fixing the IMEI number. As you probably know, your Samsung Galaxy S8 or Galaxy S8+ Plus has a unique IMEI, independent of the SIM card that you are using.

If it’s not the Radio signal and it’s not the SIM card to blame, the “No Service” error is most likely caused by a null or unknown IMEI number.

You should get all the information you need from there and make your smartphone work back.
