Possible solutions to fix SIM card not detected error on Moto G5

The following solutions are based on the probable causes. Unless you have determined the root cause, you will need to try each method until you’ll find the required fix. So here are your options.

First solution: Remove and reinstall the SIM card.

One of the common reasons as to why your device is unable to detect or recognize the SIM card is because the SIM card is dislodged or loose. To make sure this isn’t causing you this trouble, remove the SIM card from your Moto G5, check for any signs of damage, and then reinstall it.

Here’s how to properly remove and reinstall the SIM card on your Moto G5:

  • Power off your Moto G5. Your device has to be completely turned off before removing and reinstalling the SIM card. To do so, just hold the Power button for about 2 to 4 seconds and then select the option to Power Off your Moto G5.
  • Remove the back cover of your Moto G5. To remove the back cover, slowly peel off the back cover starting from the small gap (groove) located at the bottom of the phone. Just use your hands with a bit of force (but not too much). Do not use any tools which may cause damage to or break the cover.
  • Remove the battery first. Doing so will let you view and access the inside of your Moto G5 including the SIM card slot.
  • With the battery out, remove the SIM card(s) from the card slot. Inspect the SIM card for any signs of damage. If there’s none, then you may place it back into the card slot. Be sure to place the metal part of the SIM card facing downwards and the clipped corner in the upper left. Also ensure that the SIM card is placed in the lower section not underneath the slot.
  • For dual SIM versions, insert the second SIM card. Make sure the SIM cards are properly installed and secured.
  • Put back the battery and back cover.

When everything is back into place, turn on your Moto G5. The SIM card should now be detected.

Second workaround: Restart (soft reset) or forced restart (hard reset).

You may think it’s useless but a simple restart on the device can rectify minor glitches that might caused SIM card errors to occur. If the SIM card remains undetected after the prior procedures, try to restart or do a forced restart on your Moto G5 several times (about 5 times).

To do so, just press and hold down the Power button and then tap Power off. Wait for about 30 seconds and then press the Power button again until it your device powers up.

Alternatively, you can do a forced restart or hard reset on your Moto G5 with these steps:

Simultaneously press and hold the Power and Volume Up buttons for about 10 seconds or until the phone reboots, shows the Moto logo/bootup sequence and finally takes you to the lock screen.

Third workaround: Toggle Airplane Mode on and off.

The Airplane mode trick has been proven working by many people who have dealt with network-related issues on their respective Android devices. Turn Airplane mode on automatically disables Wi-Fi, Bluetooth and other connectivity features on your device while turning it off does the opposite. For some reasons, doing so refreshes the network functions and eliminates minor glitches affecting the phone’s network system.

Here’s how to turn Airplane mode on and off on your Moto G5:

  1. Tap the Apps icon from the Home screen.
  2. Tap Settings.
  3. Tap More.
  4. Tap the Airplane Mode switch located on the upper right of the screen to turn the feature on for a few seconds.
  5. After the elapsed time, tap the Airplane mode switch again to turn the feature off.

See if that gives you some luck.

Fourth workaround: Configure Network settings.

The next option you have if the previous method fails is to manually change the network modes on your Moto G5. You can switch between available network modes and see the result.

  1. Go to the Main/Start screen.
  2. Drag the Arrow Up sign.
  3. Scroll down and then tap Settings.
  4. Tap More.
  5. Scroll down and tap on Mobile networks.
  6. Tap on Preferred network type.
  7. If 4G is selected, tap to select other network type like 3G or 2G.
  8. After setting the network type, go back to the Main/Start screen.

Give your phone another round of reboot and then see if the SIM card is detected already.

Last option: Reset your Moto G5 to Factory Settings.

A factory reset might be the key to fixing the problem especially if a more intricate software error or bug is to blame. Performing a factory reset however will wipe all of the data and information on your iPhone and restores your phone software to factory settings. This is why it’s deemed as a last resort. Should you wish to proceed and give it a shot, follow these steps:

  1. Tap Settings from the Main/Start screen.
  2. Tap Backup and reset.
  3. Select the Factory data reset option.
  4. Select Reset Phone to confirm.

Wait until the reset is finished and then reboot your phone. After it’s booted up, proceed with the initial setup and then see if it’s now able to detect the SIM card.

Other Options

If none of the prior methods worked and your Moto G5 is still unable to detect SIM card, contact your phone’s carrier for other options. You may request a new SIM card if necessary. If you suspect that the problem is due to a damaged SIM card reader, you may have it replaced by a new one or take your device to a service center and have an authorized technician do the job for you.

SIM card errors in mobile devices may be attributed to software glitches or hardware damage. In most case, such error occurs among other random system issues affecting various smartphones, from basic to the highest tiered variants.

To give you some inputs on how to deal with this issue, I have listed a few quick solutions and workarounds you can refer to whenever needed. Read on to find out how to get rid of the SIM card not inserted error on your Huawei P10 / P10 Plus smartphone.

For those who are looking for a solution to a different problem, drop by our troubleshooting page for we have already addressed some of the most common issues with this phone. Browse through the page to find issues that are similar with yours and use the solutions we suggested. If they don’t work for you or if you still need our help, contact us anytime through our Android issues questionnaire.

How to troubleshooting Huawei P10/P10 Plus with SIM card issue

Before you begin troubleshooting, check and ensure that your phone software is updated. You can check for, download, and install new update available for your device first. Otherwise, try any of the following solutions.

First solution: Restart or soft reset.

A soft reset or device restart may be all you need to get rid of the error especially if this is the first time it occurs on your phone. It’s likely triggered by minor software glitches afflicting the phone’s network system. Hence, if you haven’t yet restarted your device, do so with these steps:

  1. Press the Power button for a few seconds or until the menu options appear.
  2. Select Power off option and then tap OK. Doing so will shut down your phone.
  3. After 30 seconds, press the Power button again until your device restarts.

Performing a soft reset doesn’t require backup creation because it does not affect any saved data and personal information. All it does is clearing out minor software errors and dumping cached files including corrupted data from your device.

Second solution: Remove and reinstall SIM card.

The SIM card not inserted error may also denote that the device isn’t actually detecting the SIM card because it’s dislodged from the tray. The same thing may happen if the SIM card is damaged. To check and ensure that the SIM card is secured in place and not damaged, here’s what you should do then:

  1. Power off your device.
  2. Locate the SIM slot on the left side and the insert the SIM ejection tool or a bent paper clip into the small hole.
  3. Gently push it until the SIM tray ejects.
  4. Remove the SIM tray carefully.
  5. Then take the SIM card off from the card slot. Examine the card for any signs of damage like scratches. If the SIM card is dirty, clean it gently with a dry cloth. If you suspect that the SIM card is damaged, contact your service provider/carrier and then ask for a replacement SIM card instead.
  6. If everything looks good with the SIM card, place it back into the SIM card slot with the gold contacts facing downwards.
  7. Secure the SIM card in the slot and then push the SIM tray back into the phone.
  8. Push the slide back on your phone and then lightly push on it until it snaps into place.

Once the SIM tray is secured and locked, restart your phone and then see if the error is already gone. If it persists, then try the next applicable solution.

Third solution: Boot in safe mode.

In safe mode, all third-party/downloaded apps are bypassed or temporarily disabled. This leaves only the preinstalled apps active and usable. It’s therefore easier for you to determine if the problem is caused by a third-party app or not. To enable Safe Mode on your Huawei P10 / P10 Plus, follow these steps:

  1. Turn off your phone by pressing the Power button until it shuts down.
  2. Then press the Power button again to turn it back on.
  3. As soon as you see the Huawei animation screen, press and hold the Volume Down button until your phone boots up.

You should then see a Safe Mode label on the bottom leftmost corner of the screen. If the SIM card not inserted error does not appear while in safe mode, then any of your downloaded apps is most likely the trigger. Try to think of which app you’ve downloaded and installed recently before the error started. You will need to delete that app to fix the error once and for all. If the error still occurs while in safe mode, then you’re likely dealing with a more complex system issue, if not hardware damage. Consider the next applicable solutions.

Fourth solution: Wipe cache partition.

Cache files are not only saved in apps but also in system folders of your device. And like apps cache and data, system cache may also become corrupted at some point and thereby caused system errors to occur. To clear this out, wiping cache partition is recommended. This will delete every single cache from the system cache partition. Here’s how to wipe cache partition on your Huawei P10 / P10 Plus:

  1. Power off your device.
  2. Hold the Power button and the Volume Up button simultaneously for a few seconds.
  3. When you see the Huawei logo, release both buttons. Doing so will route you to the EMUI or Android Recovery menu with a list of options to choose from.
  4. Press the Volume Down button to scroll and highlight wipe cache partition option.
  5. Then press the Power button to confirm the selection.
  6. Wait until your phone is finished clearing the cache partition and then highlights the Reboot system now option.
  7. Then press the Power button to confirm and reboot the phone.

Allow your device to boot up completely and then check and see if that fixes the SIM card error. If not, then you may have to consider performing a master reset or factory data reset.

Fifth solution: Factory data reset or master reset.

A full system reset may be considered among the last options to try on if none of the prior solutions is able to get rid of the SIM card error on the phone. There might be some tough bugs or malware that caused such an error to re-occur. Please note though that this reset will wipe everything from your device including all your saved files, settings, downloaded apps, and other personal contents. Should you wish to proceed, then you should back up all your critical data for safekeeping. Once you’re all set, follow these steps to reset your Huawei P10 / P10 Plus to its factory defaults or original state:

  1. Tap Settings from the Main menu.
  2. Scroll to and tap Advanced settings.
  3. Scroll to then tap to select Backup & Reset option.
  4. Tap Factory data reset to continue.
  5. Then tap Reset phone twice to confirm.

Wait until the reset is finished and for your device to reboot by itself. After the restart, you can continue with the initial setup process, to configure and set up your device as new. Software-related issues and errors should be all gone after the reset unless they’re attributed to a damaged hardware.

Other options

You may have to consider asking for a new SIM card replacement if none of the previous workarounds is able to fix the error and your Huawei P10 / P10 Plus still does not detect your SIM card. There’s a higher chance that your SIM card has been damaged and therefore needs to be replaced. Your carrier may also have to reactivate your SIM card.

But if you still need our help, then fill up our Android issues questionnaire and hit submit to contact us.

First solution: Reboot your phone (soft reset).

A soft reset or restart is the easiest and by far a very effective solution to different types of software problems in mobile devices. Should this be the first instance that you encounter a No SIM card or SIM card not inserted error on your Galaxy A8 2018 smartphone, then it’s likely just a random software glitch afflicting network functions of your phone.

  1. Press and hold the Power button for a few seconds or until the menu appears.
  2. Tap Power off then OK. Your phone will then shut down.
  3. After 30 seconds, press the Power button again until the phone boots.

Or you can perform the alternative reboot as demonstrated with these steps:

  • Press and hold the Volume Down button and Power button simultaneously for about 10 to 20 seconds or until the Samsung logo shows up on the screen. Then release both buttons when the Samsung logo appears.

Both these methods won’t affect saved data on your phone’s internal memory, so you won’t lose any personal information in the process.

Second solution: Remove and reseat the SIM card.

If a soft reset failed to resolve the problem and the SIM card error persists, then try to remove and reseat the SIM card on your Galaxy A8 2018 smartphone. It’s possible that your phone is telling that truth, which means it’s actually not detecting the SIM card likely because it’s dislodged from the slot. And the only way to find out is to remove and then reseat the SIM card on your device. Here’s how:

  1. Power off your phone completely.
  2. Insert the SIM ejector tool or bended paperclip into the tiny hold on the SIM card tray. To prevent causing damage to your device, ensure that the pin is perpendicular to the hole. When you hear a slight click, it means that the tray pops out.
  3. Gently pull the tray out from the slot.
  4. Remove the SIM card from the tray and then check the card and card slot for any visible signs of damage and dust-free.
  5. If everything looks good, place the SIM card back in the tray with the gold colored contacts facing downwards.
  6. Insert the SIM card tray back into the SIM card tray slot.
  7. Push the tray back in to close it. Make sure it is closed tightly to prevent water and dust from entering the device.

When the SIM tray is secured back in place, turn on your phone and see if that fixes the error. If the SIM card no detected error persists, then you may have to consider performing software resets.

Third solution: Reset network settings on your phone.

There were instances when a SIM card error occurs due to invalid network settings or options on the phone. Problems like this usually transpire after installing an update, which automatically alter or override the current network settings on the device. To clear this out, performing a network settings reset is recommended. This will clear/delete current network settings and restore the default network configurations, thus allowing you to manually configure necessary options accordingly. Here’s how it’s done:

  1. Tap Settings from the Main Menu.
  2. Scroll to and tap General Management.
  3. Scroll to and tap Reset.
  4. Select Reset network settings from the given options.
  5. Read the message from the Reset Network Settings prompt and then tap Reset Settings.
  6. Tap Reset Settings again to confirm.

Your phone will then instigate the network settings reset process and then automatically it’ll restart when done. As soon as it reboots, set up and reconnect to your Wi-Fi network to go back online with your phone. And likewise, check and see if the No SIM card error is gone. If it’s still shows, then try other solutions.

Fourth solution: Boot your phone in safe mode.

Safe mode is a state that allows only built-in apps to run. You can enable safe mode if you’re dealing with device issues that are likely associated with errant apps. To make sure that the SIM card error you’re getting is not inflicted by a third-party app, try to enable safe mode on your Galaxy A8 2018 smartphone when these steps:

  1. While your phone is on, press and hold the Power button for a few seconds until the Power off menu appears.
  2. Hold on the Power off option until the Restart in safe mode appears.
  3. Select OK and then wait for a few seconds until your device boots up in safe mode.

You will know when your device is already running in safe mode if you see Safe Mode on the bottom right-corner of the screen.

If the error is gone while in safe mode, then it means any of your third-party/downloaded apps is the culprit. In that case, you’ll need to identify which apps is at fault and then have it deleted. If the error persists while in safe mode, it denotes that something in your phone system is causing it and therefore you need to continue troubleshooting.

Fifth solution: Update phone software to the latest version.

Installing the latest software version available for your device can be the key to fixing the error if it’s triggered by some bugs or malicious software. Software updates not only bring in new features but also offer security enhancements to get rid of any bugs that might have caused problems on certain devices.

How to fix a Samsung Galaxy A8 Plus 2019 that keeps showing SIM card not inserted warning (easy steps)

When your Samsung Galaxy A8 Plus 2018 smartphone prompts you with a SIM card not inserted warning, it’s letting you know that it does not detect or unable to recognize the SIM card in it. And it’s a problem that needs to be fixed as the key services such as calling and texting are also affected.

This SIM card warning could be due to a loose, dislodged, or damaged SIM card on the phone. But in most cases, warnings and error prompts like this are usually attributed to software glitches transpiring on the network or phone system itself. Considering that the warning you see on your Samsung A8+ 2018 is attributed to software errors rather than faulty hardware, there are a few things you can try to get rid of the error and get things working properly on your phone again. Highlighted below is a rundown of possible solutions and workarounds you can refer to whenever you need some more inputs in dealing with the same SIM card warning on the same device.

For smartphone owners who found our site while trying to find a solution, try to see if your phone is one of the devices we support. If it is, then visit the troubleshooting page for that device, browse through it to find issues that are similar with yours and feel free to use our solutions and workarounds. However, if you still need our help after that, then fill up our Android issues questionnaire and hit submit to contact us.

First solution: Restart your phone.

Restarting the phone (soft reset) eliminates minor glitches that may cause similar errors to occur at random times. And more importantly, this method works without affecting data and personal information you saved in the internal memory of your device. So you can expect your files to remain intact. A soft reset or restart can be done in two ways, the usual reboot and soft reset using the hardware keys (force restart). The latter is recommended whenever the error makes your phone become unresponsive or frozen.

Here’s how to soft reset your Samsung A8+ 2018 using the hardware keys (force restart:

  • Press and hold the Power button and the Volume Down button simultaneously for about 10 seconds or until your device restarts.

Alternatively, you can do the usual restart procedure with these steps:

  1. Press the Power button for a few seconds or until the phone shuts down.
  2. Then after 30 seconds, press the Power button again to turn the phone back on.

Second solution: Remove and reinstall your SIM card.

Another way to clear minor glitches that might have caused conflict with the SIM card or cellular network system on your phone is by removing and reinstalling the SIM card. It’s also necessary whenever the SIM card is loose or dislodged in the tray. And here’s how it’s done properly:

  1. Insert the ejection pin into the tiny hole to loosen and pop the tray out.
  2. Gently pull out the tray from the tray slot.
  3. Remove the SIM or USIM card from the tray and examine the card for any visible signs of damage like scratches or dents. If everything looks good to you, place the SIM card back into the tray with the gold-contacts facing downwards.
  4. Gently press the SIM or USIM card into the tray to secure it.
  5. Insert the tray back into the tray slot.
  6. Check and ensure that the tray is secured in place and then restart your phone.

Third solution: Update your phone software to the latest version.

Installing the latest update can also be a potential solution especially if the SIM card warning or error is triggered by some bugs or system glitches that could not be remedied by any of the prior methods including soft reset. So if you haven’t done it yet, then you can give it a try this time. Just follow these steps to get started:

  1. Open the Apps screen by swiping up on an empty spot from the Home screen.
  2. Select Settings.
  3. Scroll to and select Software update.
  4. Tap the option to Download updates manually.
  5. Wait for your phone to search for available updates.
  6. If an update is available, follow the onscreen instructions to proceed with the update download and installation.

After successfully installing new update, restart or perform a soft reset on your device to implement the new changes.

Fourth solution: Reset network settings on your phone.

Performing a network settings reset can help deal with network-related errors including those pertaining to SIM card. This can be the key to fixing the SIM card not inserted warning on your Samsung A8+ 2018, especially it started occurring after you modified your phone settings or installing new apps or updates. Some updates may override your current settings automatically. And should this happens, there can only be two possible outputs — either good or bad. To rule this out, you can reset your network settings and reconfigure your phone’s network options back to the way they were before the warning transpires. Here’s how it’s done:

  1. Tap Settings from Home.
  2. Scroll to and tap General Management.
  3. Select Reset from the next options.
  4. Tap Reset Network Settings.
  5. Read and review the information displayed then select Reset Network Settings again.
  6. Tap Reset again to confirm and instigate network settings reset process.

Fifth solution: Back up and reset your Samsung A8+ 2018 to factory defaults.

You may have to consider opting system reset as your last resort if the warning persists after performing all prior procedures. It’s possibly triggered by some tough bugs ruining the network system and so a more advanced solution is required. This however could result to data loss as everything will be wiped out from your phone system in the process. This means creating a backup is necessary beforehand. Should you wish to give it a try, follow these steps to backup and restore and reset your Samsung A8+ 2018:

  1. Open the Apps screen.
  2. Tap Settings.
  3. Go to Cloud and accounts.
  4. Tap the option to Backup and restore.
  5. Enable or disable options to Restore and Back up my data as you would prefer.
  6. Go back to the Settings menu.
  7. Tap General Management.
  8. Tap Reset.
  9. Select Factory data reset from the given options.
  10. Tap Reset device.
  11. If prompted, enter your PIN or password.
  12. Tap Continue.
  13. Then select Delete All to confirm.

Your phone will restart automatically when the reset is finished. After the restart, set up your network manually and see if that fixes the problem. If not, you’ll need to consider other options.

Other options

If you’re still getting a SIM card not inserted warning on your Samsung Galaxy a8+ 2018 after performing all applicable workarounds and potential solutions, then call your carrier or network service provider to report the issue for further assistance and recommendations. Your SIM card might have been damaged and therefore a new SIM card replacement would be necessary.

Alternatively, you can take your phone to a Samsung service center and have it assessed by an authorized technician for any indications of hardware damage. Your phone might have obtained some sort of physical or liquid damage from a previous drop or liquid exposure and that might have damaged the SIM card tray or other relevant components.
