Why Does My Phone Say No SIM Card?

Your phone shows the no SIM card error because it cannot read your SIM card’s contents properly. This can happen when your SIM card is not installed correctly, it’s damaged, or your phone has software problems after a software update, just like sanchaita_dey from the Oneplus forum. Therefore, your phone won’t recognize the SIM card and will say no sim card detected.

You don’t need to get your SIM card replaced immediately, as there are some fixes that you can apply to your phone, potentially fixing your problem. If these don’t work, then you can go ahead and get your SIM card replaced.

How to Fix No SIM Card Detected On Android and iOS

Fix 1. Pull Out the SIM and Put It Back In

Since this issue concerns your SIM card, you can try ejecting it from your phone and then putting it back in. If your SIM wasn’t installed correctly or the SIM card tray was loose, this should fix that for you.

Eject the SIM card tray on your phone, take the SIM out, wait for half a minute, put the SIM card back in, and slide the tray into your phone. After the phone reboots, check if the device reads your SIM card.

Additionally, you can clear the SIM card’s Golden chip with the help of any cloth. 

Fix 2. Reboot the Device

The first trick up our sleeves is super simple – give your phone a little nudge by rebooting it! Yes, you heard that right. Sometimes, a quick reboot can resolve minor glitches and get your phone working like a charm again.

All you need to do is hold down the power button and choose the “Restart” option. Voila! Your phone will turn off and turn back on, just like magic. And who knows, maybe it needed a little break to get back on track.

So try it and see if your SIM card decides to come out of hiding. If not, don’t worry – we’ve got more tricks up our sleeves!

Fix 3. Enable and Disable Airplane Mode

The purpose of Airplane mode is to help you disconnect from all network services when you’re on a flight. However, you can use this mode to fix many network-related problems, such as not having a registered network, a WiFi connection but no internet, the phone has no service, etc. No guarantee using Airplane mode will fix your issue, but you can give it a go as it won’t harm your device.

Ensure you’ve saved your work before you do this, as your phone will also be disconnected from the Internet.

Step 1. Open the notifications panel on your phone.

Step 2. Tap the Airplane mode icon to turn the mode on.

Step 3. Tap the icon again to disable the mode.

Fix 4. Check your SIM Card

Hey there, mate! Are you still struggling with your phone saying “no SIM card”? Wait to fret because we’ve got another fix for you that could do the trick!

Fix number 5 is all about checking whether your SIM card is working. And how do you do that? Well, by inserting it into another phone! That’s right, and it’s time to call in a favor from your friends or family with a compatible phone.

Ask them to lend you their device for a few minutes and pop in your SIM card. If it works perfectly fine on their phone, then you know that your SIM card is not the culprit. But if it still shows the same “phone says no sim card” error message, it’s time to get a new one.

Knowing if your SIM card is the issue is good, so you can move on to other fixes without wasting time. So give this one a shot, and let us know if it worked for you!

Fix 5. Reset Network Settings

Once you’ve done this, your network settings will be reset to their default state. This can be helpful in situations where your phone’s settings might have been altered, causing your SIM card not to be detected.

But don’t worry; resetting your network settings won’t delete any of your data, so you won’t have to worry about losing anything important. It’s a simple solution that could fix your SIM card issues.

Fix 6. Is SIM card Enabled?

Check if your SIM card is turned on or off from your mobile settings; follow these steps:

  1. Open the Settings app on your phone.
  2. Look for the option “SIM Card” or “Mobile Network” and select it.
  3. Check if the toggle for your SIM card is turned on or off. If it’s off, turn it on.
  4. If you have multiple SIM cards, ensure the correct one is selected as the default for data and calls.

Fix 7. Check the Network Type

As someone who works at a phone store, the first step is checking the phone settings. You can do this by going to Settings, Connections, and Mobile Networks. If the setting is set to GLOBAL, change it to LTE/CDMA. In many areas, LTE works better than 5G, which is what the GLOBAL setting is for.

If changing the setting doesn’t help, the next step is to get a new SIM card from your carrier. Sometimes SIM cards can be faulty, and replacing them might solve the issue.

Another option is to update your phone software. Although this doesn’t usually fix the problem, it has sometimes worked.

If none of the above options work, the issue may be due to poor coverage in your area or a faulty phone. Let us know if we missed any troubleshooting steps!
