However, in addition to this, you may also not be able to use your SIM card due to incorrect settings on your device. Hence, you can follow the steps below to reset your network settings so that your SIM card works.

3. Check if your SIM card is active.

When using all these methods, it is also very important to check if your SIM card is active or not. After purchasing a new SIM card, the carrier must also activate the services.

If your SIM card is inactive, you can replace it with your carrier. However, if this doesn’t work for you, you must bypass the SIM card and activate with another activation plan.

The easiest way to go through this method is to activate the SIM card when you buy it and verify the same with your carrier. This will avoid unnecessary problems when inserting the card into the iPhone.

4. Software update

Devices must have numerous bugs and glitches. There may be times when rebooting the device over and over again is ineffective.

Also, you may want to check the most recent iOS software because there might be bugs in the system itself. Other features may work correctly sometimes, but certain iPhone features stop working due to missing bug fixes.

Apple releases updates regularly to avoid problems. Sometimes these updates are primarily about new features, with the developers focusing on fixing bugs that are often related to settings. You can easily install the update by connecting to Wi-Fi or Bluetooth to connect to the Internet.

However, if the update includes bug fixes and other resolved issues, you can follow these steps directly.

• Go to the settings menu.
• Select General.

• Scroll to “Software Update”and select it.
• Click Download and Install if an update is available.
• Click “install”after downloading.

You can also choose to install the software immediately or schedule it later.

Updating your software is sometimes seen as the first or last option to resolve these issues. One of the main reasons is that other options are often not checked.

However, if all settings are checked and users are still unable to receive notifications from the app, it is more likely that the iOS software will contain bugs or glitches.

Usually developers solve the problem quickly and send a new update.

5. Switch flight mode

You can change the Airplane Mode settings on your iPhone. Enabling airplane mode will prevent your device from using all SIM card services. However, turning airplane mode on and off can also fix the problem.

To make sure this isn’t the case, you can toggle Airplane Mode on and off in Settings.

6. Make an emergency call

An emergency call will help you use your SIM card or even activate it sometimes. This is one of the reasons why you can use your SIM card again during a call. Since you won’t be able to do this with a regular call, an emergency call is an integral part.

You can either press the home button on your device or activate emergency calls three times. You can dial any emergency number you know, 112/121/911. You can then disconnect the call immediately after the connection.

This method can help you activate the SIM card and get the signal back without resetting the network settings.

7. Reinsert the SIM card

Depending on your iPhone model, you will have to find a SIM tray. For most iPhones, including iPhone 8, X, Xs, XR, SE, 11, 12, and 13, the SIM tray is on the side of the iPhone.

You can take it out with an ejector or a paper clip. After that, remove the SIM card from the tray. Make sure there is no dirt or debris on it and then reinsert it.

Once you do that, you can check if your iPhone supports it or not. Otherwise, you can also reboot your phone, which will reboot the device itself.

If this method does not work for you, you can also try the following methods: through the IMEI service or check with your carrier.

8. Use the IMEI service

One of the best and easiest ways to unlock a SIM card is with the IMEI service. You can access these tools at any time and the only thing you need is to request a service to have your device unlocked at any moment.

However, you should also keep in mind that most of these services are not free. That is why this service can be considered the last resort to solve the problem. However, you do not need to install any application or software.

With this service, you can unlock your device relatively quickly and resolve the Sim Not Support error easily.

9. Check carriers

Another reason why your phone is experiencing the “SIM not supported” error might be because the carrier itself has blocked it. Therefore, in order to unlock your SIM card, you need to contact your carrier.

You may also have to make payments when you try to unlock your SIM card. As soon as the payment is made, the operator will automatically unblock it. However, if you still have time before the end of the contract, you can try other ways to resolve the issue, as they seem to be more favorable.
