Troubleshooting network problem on your Galaxy A8 2018

The following is a rundown of standard procedures and workarounds to deal with No SIM card error on your new Android phone. There is no definite fix given that the underlying cause in yet to be determined but any of these methods can offer some remedies.

Reboot your Galaxy A8 2018 (soft reset).

It is typical for smartphones to experience random network problems like a No SIM card error due to many different factors. But the good thing is that most these issues are inflicted by a software glitch, which is rectifiable by a soft reset or device restart. That said, performing a soft reset or device restart is the first recommended solution to any random software issues on the device. Here’s how to reboot/soft reset your Samsung Galaxy A8 2018:

  1. Press the Power button for a few seconds until the power off menu appears.
  2. Tap to Power off the phone.
  3. Or simply press and hold the Power button until the device powers down. Wait for about 30 seconds and then press the Power button again until the device powers up.

If you’re still seeing a No SIM card error after the first restart, give it another try. Sometimes, a single restart may not be enough to rectify the software error.

Enable Airplane mode for a few seconds then disable again.

Another simple trick used by many Android phone users who have dealt with network-related errors including the No SIM card is by switching Airplane mode on and off. It turns out that doing so can somehow refresh the network system and eliminates minor flaws. It won’t hurt if you try it too and then see how it does. Here’s how to enable or disable Airplane mode on your Samsung Galaxy A8 2018:

  1. Tap Settings from the Home screen.
  2. Tap Airplane mode.
  3. Then toggle the switch next to Airplane mode to turn the feature on for a few seconds and then tap to turn off again.

Reboot your phone then try to see if that fixes the error.

Remove and reinstall the SIM card on your Galaxy A8 2018.

The No SIM card error can also occur when the SIM card is dislodged or loose. This can be your phone’s way of letting you know that it’s not able to detect the SIM card even when it’s inserted simply because there is no established physical contact. To rule this out from the possibilities, you can remove and reinstall the SIM card on your device. Follow these steps to remove and reinstall SIM card on your Samsung Galaxy A8 2018:

  1. Power off your device.
  2. Locate the SIM card tray on the left side of the phone.
  3. Insert the SIM eject tool into the tiny hole on the SIM card tray then press  a bit for the tray to pop out. If you don’t have a SIM eject tool, you can use a small paperclip or an earring wire instead.
  4. Carefully remove the SIM card from the tray.
  5. Place the SIM card back into the tray. Make sure that the SIM card is properly installed and secured in the tray.
  6. Insert the SIM card tray back into the slot and then press a bit to close the tray.
  7. Press the Power key to turn on your phone.

Wait and see if the No SIM card error is gone.

Check for carrier settings and software updates to install.

Installing a carrier settings update or latest Android version on your phone can likewise be a potential solution especially if the error is associated with unsupported carrier settings. Meanwhile, updating the device software to the latest Android version available can be the ultimate fix especially if the error is triggered by software bug. Software updates not only offer new features but also bug fixes to address existing software problems on an Android device.

You can check for updates by going to Apps-> Settings-> System updates menu.

If there’s an available update for your device, back up your data then follow the onscreen instructions to download and install the update file.

Diagnose your phone in safe mode.

Booting into safe mode can help you determine if the problem is triggered by some third-party apps or not. All third-party apps and services are bypassed or disabled in this state. Here’s how to boot your Samsung Galaxy A8 2018 in Safe Mode:

  1. Turn off your phone.
  2. Press and hold down the Power key until the Samsung logo appears.
  3. Tap Restart twice on the following menu. Doing so will reboot your phone.
  4. While your phone is restarting, press and hold the Volume Down key for about 10 to 20 seconds.
  5. Release the Volume Down key when the phone powers up again. You will then see Safe Mode at the bottom side of the screen and that means your device is now running in safe mode.

Check and see if the No SIM card error still shows up while in safe mode. If the error doesn’t occur in safe mode, a third-party app is the culprit and that’s what you need to identify. You can try to individually remove your recent downloads if you’re not sure of which app is the trigger. But if the No SIM card error still pops up while in safe mode, then you’ll need to troubleshoot software problems on your device.

Perform a factory data reset.

A factory reset will wipe all your data and personal information from the phone. Should there be any bugs or corrupted data dwelling in the system registry of your phone, that will also be eradicated in the process. The only downside from this reset is data loss. But then again, this might be the key to fixing the error. Should you wish to proceed with this reset, be sure to back up all your critical data beforehand. Then follow these steps to perform a factory data reset on your Galaxy A8:

  1. Tap Settings.
  2. Tap Backup and reset.
  3. Select Factory data reset.
  4. Tap Reset device then Erase everything to confirm.

Wait for your device to reset settings to the factory default values and delete all data. After the reset, your device reboots.

If the error is gone after the reboot, then you may proceed with the initial device setup. Otherwise, contact your carrier for more options.

Troubleshooting Galaxy S9 Plus that can’t detect SIM card

Here in this context, I have compiled a rundown of possible solutions that you could refer to whenever you’ll be required to troubleshoot a similar issue on the same phone. These are generic solutions that have been tried on and proven effective by many other Android phone users who have dealt with pertinent SIM card errors that were attributed by software bugs and glitches. Feel free to refer to these solutions whenever needed.

First solution: Restart your phone (soft reset).

To fix minor software glitches that might have caused the error to occur on your phone, start by performing a soft reset or simply restart your Samsung S9 Plus. It’s the first recommended and proven effective simple solution to various types of software issues in mobile devices, be it an iOS or Android phone. And here’s how it’s done:

  1. Press and hold the Power button.
  2. Tap the option to Power off.
  3. Tap Power off again to confirm.
  4. After about 30 seconds, press and hold the Power button again until your phone boots up.

Alternatively, you can carry out a simulated battery removal equivalent procedure otherwise known as forced restart. It’s actually a soft reset using the hardware keys and it’s done this way:

  1. Press and hold the Power and Volume Down buttons simultaneously for up to 45 seconds.
  2. Release both buttons when the Samsung logo appears.

Both a soft reset and forced restart won’t result to data loss as they will not affect any data and personal information stored on the internal memory of your device.

Second solution: Reinstall/reseat the SIM card on your phone.

There are times when you would need to remove and reseat the SD card and/or SIM card on your device. And this is one of these instances when you have to try doing so. It’s possible that your phone does not really detect your SIM card because it’s somehow loose or dislodged. That said, the SIM card needs to be reseat to make it intact and secure.

  3. Slide the nano SIM/microSD card tray out of the slot.
  4. Remove the SIM card from the tray and check for any signs of damage. If the SIM card looks good, place it back into the tray with the gold contacts facing the back of the phone. To prevent damage, do not touch the gold contacts on your SIM card.
  5. Press the nano SIM/microSD card tray back into its slot until it clicks.
  6. Once the tray is secure, press the Power button to turn your phone back on.

Reinstalling the SIM card as demonstrated by the above procedures can also fix minor glitches affecting the SIM card reader system, which likewise might have resulted to this error.

Wait until the phone completely restarts and see if the error is gone. It it reoccurs, then you may need to resort to a full system reset else consider repair options.

Fifth solution: Hard reset/factory data reset.

A factory data reset or hard reset on your Samsung Galaxy S9 Plus can be regarded as the last resort when dealing with complex software issues that might have prevented your phone from detecting the SIM card and prompted you this error instead.
