Is your android SIM card unreadable? If yes, of course you must feel sad, upset, confused, and dizzy. Basically SIM Card is one type of micro sim that functions as a tool to store and be an additional tool for communicating between one user and another user.

In the modern era, the development of android smartphones is increasingly sophisticated. And most sophisticated smartphones definitely adopt thin models.

And to make the thin design there are some parts that are made compact and a little simpler.

For example, you can see a product from SAMSUNG, which narrows the SIM card down, making users have to cut it to fit and be installed. And this is the problem of smartphone users in Indonesia who cut SIM cards with cutting devices that are not supposed to be used.

So that makes android unable to read the sim card that he has installed. Maybe it happened because of the pieces that do not fit because if even a little cut off then the SIM Card will also not be detected.

Apart from that, there are several other causes that make the sim card unreadable. And the following causes.

1. SIM Card is no longer suitable to use

Older SIM Cards or those that are more than 5 years old, it’s only natural that your SIM Card is no longer readable because the SIM Card is outdated and is no longer suitable for use.

In addition, the state of the brass sim card is also not very good, maybe it’s a little black. For this reason, you should replace your SIM Card with a new one.

2. Brass Line Damaged

As you can see that the SIM Card is visible in yellow, which means it is the most important part of a SIM Card.

That part is very sensitive, if there are other objects that make the brass sim card scratched too deep and make the brass line cut off then there will be damage.

So that the SIM Card will no longer be read by Android.

3. Overheating

A technological device that experiences overheating or excessive heat will make the device quickly damaged or error, including the SIM Card.

Excessive heat due to gaming or internet activities can make the sim card burn or melt, because we know that the SIM Card is made of brass and plastic.

Apart from the 3 causes above, there are still many other causes which I cannot write one by one. To overcome these unreadable sim cards, try the following tips.
