Ever wondered are sim cards waterproof, will a sim card be damaged by water or probably not, and you may be all wrong thinking water will damage your sim card.

There’s no doubt that water damages the mobile phone, but this may be quite different with sim cards. So this is what this post is all about, explaining if indeed sim card can be damaged by water.

So let’s jump in.

Are sim cards waterproof?

The answer is yes. Sim cards are waterproof and cannot be damaged by water even if the sim card falls into a five liter of water though it depends on the sim manufacturer.

Sim cards are waterproof and you don’t need to bother yourself thinking if your sim card can be damaged by the water. If your mobile phone falls into the water, your phone might get damaged but nothing will happen to your sim card.

And I mean absolutely nothing will happen to your Sim card, and no need asking are sim cards waterproof.

I’ve seen cases where some number of persons claimed that water damaged their sim card, but this is very rare to see and depends on how the sim cards damaged by water are made.

My sim card has fallen into a deep water multiple times and all I have to do is to use a clean cloth and dry the water off. Afterwards the sim card will still be working very properly.

If you sim card gets damaged by water, it simply means your sim carrier made a cheap sim card and it is not waterproof.

There are things that can damage a sim card and they are as follows.

1. Using a hard object on the sim chip

The most important part of a sim card is the sim chip, once the sim chip is damaged the sim card becomes useless and will require a sim replacement.

It is advisable not to try to use a hard or sharp object on the sim chip cause there’s a likelihood that it will damage the sim card.

2. Heat can damage a sim card

Aside from the fact that sim cards are waterproof, heat can damage a sim card. This is quite rare to see but it does happen and I have seen an occasion where a sim card was damaged because of heat from the phone.

Heat from the phone can cone from different ways, even over charging your phone while mobile data or the Wi-Fi is on can cause the phone to get heated up.

3. Faulty sim slot

I’ve seen this very often in forums and social media, people that got their sim card damaged while trying to pull out their sim card from the sim slot.

This is why I’m not a fan of excessive switching of sim cards from one phone to another cause the sim card chip might get damaged in the process removing the sim card from the sim slot.

While trying to remove your sim card from the sim slot, always be careful else you might end up damaging your sim card in the process.

These are what can damage your sim not the water, so no need asking are sim cards waterproof cause the answer is a big yes. Sim cards are waterproof and can’t be damaged by water.

It is not because I said sim cards are waterproof will make you to go wash your sim card, always dropping it into the water. I’m as much nothing will happen to your sim card, I don’t recommend you to wash your sim card with water or always dropping it into the water.
