21 Different Ways to Fix No SIM Card Detected Error on Android Phone or Tablet
So without further ado, here are 21 different ways to fix the phone saying no SIM card issue on Android phones or tablets.
Restart your Android phone by turning your Android off, then switching it back on. If you just inserted a new SIM, many phones won’t even recognize it until you restart the device.
This method is probably the simplest way to resolve minor problems of any kind when it comes to your Android.
Remove Battery (If Applicable)
Go turn off your phone and unplug it from any power source. Remove the battery and wait 30 seconds or more.
After doing so, put the battery back in place and turn on your device.
Adjust SIM Card
The SIM card must be seated in your Android properly. Your SIM card is what connects you to your network, so this is crucial.
If you accidentally dropped your Android, the SIM can become misaligned, or it may not have been installed correctly from the start. Make sure to place the SIM securely on your device.
If the SIM does not fit well on your phone, you can try placing a tape, cardboard, or paper into the tray for a tighter fit. Although it might seem like a cheap way to rig your SIM’s connection, this method works for many.
Also, be careful in handling the delicate parts of your device. Never use too much force to avoid any further damage to your Android.
Manually Select Carrier/Network Operator
Sometimes, your settings will change all of a sudden. This change will sometimes cause the network to disconnect.
Many manufacturers use the Android operating system. So if these instructions differ from what you see on your user interface, you can also visit the manufacturer’s website for help.
Manually select your network operator:
1. Go to Settings.
2. Look for Wireless and Networks.
3. Tap on Mobile Networks.
4. Select Network Operators.
5. Search for networks manually.
Alternatively, on some phones, it will be:
1. Go to Settings.
2. Look for Wireless and Networks.
3. Select Data Usage.
4. Tap on the three vertical dots in the upper-right corner.
5. Select Cellular Networks.
6. Tap Network Operators.
Change Network Mode to Auto
Changing your Network Mode to Auto allows your device to select the best network for you, automatically. If you aren’t familiar with this option, follow these step-by-step instructions below.
Set your Network mode to auto-connect:
1. Go to Settings.
2. Look for Mobile Networks.
3. Tap Network mode.
4. Select “LTE/3G/2G (auto connect).”
Clean The SIM Card
Examine your SIM card. Is it dirty? Is the gold side clean?
Perhaps you can remove dirt or debris. Clean the spokes/connectors on your SIM card and reader with air or a soft dry cloth.
Handle the SIM card with care. You wouldn’t want to damage the card unintentionally.
Some Smartphones, especially the latest ones, tend to have a smaller tray for the SIM Card. Which may require you to downsize your standard size SIM card.
If that’s the case, did you cut a standard size SIM down to micro or nano size? If so, kindly observe the SIM Card.
If there are any damages incurred with the gold plates, you may have to replace your SIM.
Remove and Re-Insert SIM Card
Make sure you turn your Android off before installing or removing SIM cards—otherwise, you may harm your device or the card. Take care not to scratch or bend the SIM card.
For some devices, the SIM tray is located directly behind the volume buttons. For other Androids, you can access the SIM by sliding off the back cover and removing the battery.
Test SIM Card
See if someone with the same provider will let you try the SIM card out in their phone, and vice versa. This method is highly advisable before you try to purchase another SIM.
If the other device is unable to read your SIM, the problem is likely with the card, not your device.
Toggle Flight Mode
Enable, then disable Flight Mode. This option disables all broadcasts and cell reception when you toggle it on.
Some phones provide easy access through Quick Settings with a swipe down from the top of the screen. Another easy way is to hold down the Power button, or you can go through the Settings option as well.
Make sure that you don’t leave Flight Mode turned on.
Clear Android Cache and Data
Sometimes, the solution to this issue is clearing your Android’s cached data. Things may take a little longer to load next time, and you will probably have to log in to some of your apps again.
Clear your Android Cached data:
1. Go to Settings > Storage.
2. Look for Storage Settings.
3. Select Internal Storage.
4. Tap Cached data.
Check the SIM Tray
If the SIM tray is broken or damaged, it could be the cause of your phone saying no SIM card detected error. Don’t worry! Merely replacing the SIM card container can fix your problem.
Alternatively, using paddings that we spoke of in Method 3 — Adjust the SIM Card — can also be used to adjust the tray by using a piece of foam to apply pressure.
Apply the foam by removing the back cover and placing it over the SIM card area. Replace the back cover.
Does this happen everywhere? Is it constant or intermittent?
Carrier service must be available where you are located for your SIM to work.
Are you next to people with the same provider who have service? What about people in a different area?
Reliability is influenced by how close you are to the towers.
Contact Customer Service
Have your phone handy when you check with the service center, in case they ask for information like the IMEI number. They may replace your SIM card, the slot reader, or possibly even your Android, but it depends on the nature of the problem.
Sometimes all it takes is for your carrier to activate your SIM from within the store.
Uninstall Problematic Third-Party Apps
One possible thing that prompts the “No Sim Card Detected on Android Phones” issue is due to third-party apps. To verify that third-party apps do not cause it, run your device in Safe Mode for 2-4 hours.
If it works, an app might be the cause of the issue. Safe Mode runs only system defaults so that you can rule out any third-party apps that can be the root of the problem.
If you already suspect that a particular app may be the problem, try uninstalling it first. Otherwise, use the process of elimination.
If you aren’t using a SIM and you solely want the error message to go away, you can go to the Google Play store app and search for notification blocking apps.
If all else fails, your last trump card would be Factory Resetting your phone. Do keep in mind though that this will wipe everything back to its factory default settings.
Therefore, we highly recommend doing a full backup beforehand.
You should be able to reset from the Settings menu. Choose Backup & Reset, then Factory Reset.
Reset Network Settings
Another easy fix for the phone says no SIM card detected Android issue is to clear your network settings back to their defaults. To do this, go to Settings > Backup & Reset > Network settings reset.
Check for any available OS updates by going to Settings > Software Updates > Download updates manually.
Go Back to Original ROM
If you recently flashed your phone with different ROM, it could potentially be the culprit that causes this issue. If the SIM is detected before you do it, then there’s a high chance that the error occurred due to ROM flashing.
Restoring the original ROM of your phone will fix the issue. To do this, boot into Recovery Mode then perform a factory reset. From there, proceed to Backup & Restore and hit Restore.
If your phone has physical or liquid damage, replacing it with a brand new Android phone may be necessary.
