There are advantages to performing a system reset. As a result of this procedure, memory (RAM) is flushed, and running apps are shut down. Consequently, your gadget is restored to a “fresh” condition after being overwhelmed with data. If you overdo it, there are no negatives to this solution. However, you might reduce a device’s lifespan due to repeated reboots. It is why it is recommended to restart a mobile phone once a week by specialists in technology.

An alternative to fixing the SIM card issue is removing and re-inserting the SIM card. Misalignment may be the basis of the problem with an invalid SIM card. Avoid scratching the SIM card by being cautious when withdrawing and re-inserting. If this happens, the problem might get worse. If the device still cannot read the SIM card, check if the network provider settings have been changed. Ensure you’re on the right network for your device and SIM card to function.

A standard solution for connectivity issues is to reset network settings. However, you may also use this to solve the problem of an invalid SIM card. Only Wi-Fi, cellular, and Virtual Private Network (VPN) will return to their default settings if you reset your network settings. Make a note of the Wi-Fi, cellular network, and VPN ID or password ahead of time because you’ll need them later. For those taking to the skies, the setting known as “Airplane Mode” is a necessity. It switches off your cellular network to avoid interfering with the aircraft’s signal or communications.

The mode also preserves your phone’s battery life, which is used to seek out signals. When Airplane Mode is activated, and off, the device’s network settings are updated. It is analogous to looking for a cell phone service provider’s signal. A new network check is performed on the SIM card by your device as a consequence.

To be certain that the problem isn’t with the network but rather with your sim card, try another sim card from the same network provider and check whether it works. If this is the case, simply take out the sim card and re-insert it. Your sim card is to blame if it is detected and network service is available.

A faulty sim card might be to blame if your phone finds itself in flight mode. There have been several reports of this issue, and after some investigation, it was determined that the sim card itself, rather than the sim slot, was to blame.
