eSIM Security: Can It Be Hacked, or Tracked? Risk & Tips (2024)

Have you ever thought about how the tiny card in your phone holds the key to your connectivity? The SIM card is a small chip connecting you to the network. That allows you to call, text, and use data. But there's a new player in town: the eSIM. An eSIM is built right into your phone. You can't touch it, see it, or swap it out.

When we talk about safety, imagine your phone as a house. A traditional SIM card is like a door with a lock. It keeps your information safe, but if someone gets the key (the SIM card), they can unlock the door. An eSIM, on the other hand, is like a door with a code.

It's not just about the lock but the constantly changing code. You can't just pick it up and walk away with it. So, can this high-tech digital lock be picked? Can someone crack the code to your eSIM? It's a question worth asking, especially when our lives are connected to our devices.

The truth is, while eSIMs are designed to be secure, no technology is unbeatable.

Can eSIM be Hacked?

Are you thinking about your eSIM? Can someone hack it? eSIMs are the new revolution in the digital landscape. They came around in 2013, like invisible SIM cards built into your phone. Just choose a plan, and you're set to call and text.

Because eSIMs are built-in, no one can just take it out and put in another one. That's a relief, right? But no secret is perfect. Even eSIMs can be tricked, but it takes work. Hackers would have to be clever to break those codes. Although eSIMs aren't perfect, they're still challenging to hack.

What can you do? Keep your phone's software fresh and updated. Use a strong lock, like a fingerprint or a face scan, if possible. And pick a network that cares about security as much as you do.

While discussing a Network that cares about your security, I can not trust anything more than what I’ve tried and tested. Here’s my Recommendation.

Are eSIMs Safe?

An eSIM is soldered directly onto your phone's motherboard. You might wonder, "Is this change a step forward in security?" Well, imagine a world where losing your phone doesn't mean a stranger can pluck out your SIM and hijack your identity. With an eSIM, your information is planted inside the phone.

So, while no technology is a fortress, the eSIM is like a guard, standing watch over your digital life. And as we all know, a good guard makes all the difference when feeling safe.

Minimized Swapping Attacks: Why Your Phone Number Stays Yours

Have you ever worried about someone popping out your phone number and pretending to be you? With Minimised Swapping Attacks, that worry is a thing of the past. eSIMs are built right into your phone. No one can just take your SIM and swipe your number.

Encryption: Your Conversations in a Secret Code

What if your words become a secret code as soon as you say them? That's what Encryption does for your eSIM. Every call, every message you send is scrambled into code. Only the person you're talking to can unscramble it.

Authentication: The Secret code to Enter

Does your phone have a password, and only you know it? That's Authentication. The network won't let anyone in if it doesn't recognize the code. It keeps your phone secure.

Secure Element: A Locker Built into Your Phone

Do you have a safe locker where you keep everything valuable? Like a safe, there’s a protected space in your phone where your details are stored. It's tough to crack.

Is it possible to clone an eSIM?

Let's examine why cloning an eSIM is more complex than making a quick photocopy.

When you download an eSIM, it's like sending a secret message only your phone can open. This message is scrambled up, and only the eSIM chip can unscramble it.

Now, the question pops up, "What if someone copies that secret message?" Each eSIM setup uses a unique QR code. Once it's used, it's done. A hacker can't just slap your QR code onto another phone.

So, can eSIM be cloned? It's like trying to bake a cake without a recipe; it's possible, but it's really, really hard, and most won't get it right.

eSIM Security Risks

Let's talk about eSIMs and safety. Let’s say your phone is like your house, and the eSIM is a unique lock on the door. Thieves can't just take the eSIM out like they could with a regular SIM card. They'd have to take the whole phone!

Even though the eSIM is stuck in the phone, hackers have clever ways to trick the system. They can pretend they're you and try to get into your phone. It's like someone making a copy of your house key without you knowing.

So, what can you do? Just like you keep your house safe, you need to keep your phone safe, too. Make sure you have a sound 'alarm system'—that means a strong password or maybe even your fingerprint.

Now, you might wonder, "Has anyone ever broken into an eSIM?" Well, it's not common, but it has happened. That's why the people who make phones constantly work on better locks and alarm systems.

Can eSIM be tracked?

Ever have this question raised in your mind: can someone track your phone when you're using an eSIM? That’s not overthinking; thinking about privacy is necessary.

eSIMs are built into your phone. They do the same job as the old SIM cards, but you can't touch them. Now, because they're part of your phone, some folks worry they might be easier to track. But here's the thing: eSIMs are only trackable as the SIM cards we've used for years.

Just like with the old SIM cards, as long as your phone's connected to a network, someone can figure out where you are. That's not new. It's not particular to eSIMs. It's just how phones work.

You might have heard someone say that eSIMs can be tracked without you knowing. But that needs to be corrected. Like old SIM cards, you must give your okay before an eSIM wakes up and starts working.

So, your phone, whether it has got an eSIM or a regular SIM, can be tracked, but only in the usual ways. The real tracking happens through the phone itself, not the kind of SIM it uses. Every phone has a unique number, called an IMEI, and that's what's used for tracking.

But don't worry, you've got some control over this. You can turn off location services on your phone so apps don't know where you are. You can decide which apps get to know your location and which don't. And if you're serious about keeping things private, you can use a VPN, which is like a secret tunnel for your internet.

Remember, it's good to watch what your phone is sharing. Check those app permissions. Turn off location services when you don't need them. And be thoughtful about what you share online. After all, the best way to keep a secret is not to tell anyone, right?

FAQs for Can eSIM be Hacked?

Is eSIM Safe for Banking?

The short answer is yes, but with a caveat. eSIMs can't be physically removed, which means a thief can't just pop out your SIM and access your bank account. There have been cases where bad actors rewrite eSIM information and take control.

Is eSIM Dangerous?

Danger is a strong word. eSIMs aren't lurking in the shadows waiting to pounce. Hackers have been known to hijack eSIMs and siphon money to Bitcoin or even spread malware. It's not everyday stuff, but it's enough to make you think twice about your digital safety net.

Is eSIM Weaker than SIM?

"Strong" and "weak" are relative to eSIM vs. SIM. eSIMs are the new kids on the block, and they're pretty tough in their own right. They're designed to be secure and versatile, hopping from one network to another without a hitch. But, like any technology, they could be better.

What Happens if a Phone with eSIM is Stolen?

This is where eSIMs shine. If your phone is stolen, the eSIM stays put. Thieves can't just swap it out. But that doesn't mean your troubles are over. Your eSIM holds your digital identity, and if someone cracks that code, they could get access to your digital life.

The good news? It's not easy to do, and you've got layers of security on your side.
