Invalid SIM card or no SIM error can be encountered at any time. This happens regardless of whether your gadget uses Android or iOS. You will know if there is such a problem after your device shows the warnings “invalid SIM card”, “no SIM card” or “SIM card not detected”.
There are many reasons why a SIM card can be invalid or cannot be detected by the mobile device. First, there may be problems with the SIM card itself. The chip may be damaged or not seated properly in its dedicated slot. Second, there may be hardware problems. For example, the SIM card reader component of your device is not working properly.
There may also be software bugs. For example, your device has a very old version of Android or iOS or has problematic apps. Finally, your phone may not be network unlocked, which is why it doesn’t work on other SIM card providers.
You won’t be able to determine the exact cause right away because you will only find it depending on which solution works. Luckily, there are plenty of tweaks you can try for your Android and iOS devices.
