Unfortunately, there isn’t a single cure that will work for everyone to repair the error message, which can have a number of different causes. Even when you have correctly placed a SIM card on your device, it is annoying when your phone displays messages such as “No SIM card,” “Emergency calls only,” “not Registered on Network problem,” or “SIM card not recognized.” Like the user mentioned above, if your Samsung phone repeatedly displays “no SIM card inserted,” you will be unable to send texts, make calls, or otherwise operate the device normally. This may even result in the SIM card’s data being lost. ..

If you are experiencing a No SIM Card Error on your iPhone or Android device, we recommend following these steps:

  1. Check if the SIM card is inserted correctly. If it isn’t, try inserting another SIM card and see if that fixes the issue.
  2. Reset your phone to factory settings. This will erase all of your data and start over from scratch.
  3. Check your network provider and see if they have any solutions for this issue.

Steps to Fix No SIM Card Error on iPhone and Android

Reboot or Shut Down Your Phone

For Android:

To restart your phone, press and hold the power button until the pop-up window appears. Tap on the Restart option to restart your phone. ..

This can fix a lot of problems if this isn’t enough to fix the “no SIM” error. You can try to shut down your phones (wait 30 seconds) and then start it up again.

For iOS:

When you slide your finger across the slider to turn off your iPhone, be sure to hold down the power button until you see “slide to power off.” To turn off your iPhone, move your finger from left to right across the slider. When the phone has switched off, press and hold the power button to switch on the iPhone.

To get to the “slide to power off” screen on an iPhone X or newer, press and hold the power button and either volume button and then press and hold the home button.

Switch Your SIM Card On

If you have an Android phone that has been updated to a recent version, and if the error message “SIM not found” is displayed when you try to use your SIM card, then it may be that your SIM card is actually switched on. To check this, open the Settings app and select the General tab. If your phone says that your SIM card is not connected, then it means that yourSIM card is not actually connected to your phone.

To turn on your SIM card, go to “Settings -> SIM cards & Mobile Networks.”

If you have a dual-SIM setup, this is also the screen where you can make sure that the SIM card you want to use is switched on.

Change the Network Mode to Auto

If you have a LTE/WCDMA/GSM phone, you can try changing your network mode to auto. This can be done by going to “Settings -> SIM cards and mobile network -> Preferred network type” and choosing the first option, which will be LTE/WCDMA/GSM (auto connect).

Choose the Correct Network Operator

If your mobile network is not the one that’s automatically selected, you’ll definitely get the SIM card error. To make sure you have the right one, go to “Settings -> Mobile Networks -> Automatically select network.” Once your Android device is done searching and displays the results, tap on your carrier.

For iOS, go to “Settings -> Mobile Data -> Network Selection.” Here, turn off Automatic network selection and manually select your carrier from the displayed list.

Final Words

If you’re experiencing this issue, we recommend that you try the following steps:

  1. Reset your iPhone or Android smartphone to its factory settings. This can be done by going to Settings -> General -> Reset -> Reset everything.
  2. Try a different SIM card. If your phone is using a default SIM card, changing it may help fix the issue. If not, you can try looking for a new or compatible SIM card online or in a store.
  3. Check your phone’s battery level and charge it if necessary. Once your phone is fully charged, try restarting it and see if the issue goes away.
