How to make sure your eSIM doesn’t get hacked
The physical sim card (subscriber identity module) is first, and now we have ESIM (integrated SIM) – the most recent technology which is supported by almost all modern mobile phones, and which deletes the need for a card in which you enter and out of your device.
There are many advantages in Esims. They are easier to configure (you do not need to wait for a card to come by post), it is easier to change figures (you can manage it with only a few taps inside an application), and this makes the international Travel simpler (you can switch between ESIMS specific to the country as needed).
The Esims are also safer than their physical counterparts, for the reasons we will say below, but that does not mean that they are the hairy test. Whether you have already gone to one or think about it, here is what you need to know about ESIM security.
Which makes esims more secure
The absence of a physical card is the main reason why ESIMS are safer than standard Sims: there is no way that a thief can get an ESIM out of your smartphone, put it in another device and pretend to be you. Instead, ESIM information – your number, identity and network settings – are on a programmable chip built in your phone.
Due to their operation, esims are also easier to manage remotely. You can often manage all your ESIM settings inside the companion application provided by your operator or your ESIM company. If your number is used in any way, you should be able to stop communications remotely from another device.
The data on an ESIM is encrypted, which makes it very difficult for anyone to falsify the information that these modules contain or adjust their parameters, even if they have physical access to your device. They are also more difficult to clone due to the additional security barriers in place, which makes identity theft less likely.
In addition, the initial ESIM configuration process is closely controlled and difficult to get around. The dedicated ESIM operators and suppliers perform a variety of checks to make sure you are who tell you that you are and that the ESIM data number or connection is saved with the right device.
It should also be mentioned that the use of ESIMS for access to data abroad means that you are less dependent on public Wi-Fi networks than if you have a physical SIM card, do not annoy a functional data plan in your location and that you only use Wi-Fi to connect. These networks are delivered with their own security vulnerabilities, because you can never be completely sure of how they have been put in place or who is connected to them, so the less you spend time, the better.
Why you have to be careful
Despite all the safety benefits with which Esims sees, they are not immune to potential hacking attacks. SIM exchanges are always possible: this is where someone invades you so that your number is moved to another device, deactivating it on yours. If this happens, you will notice quickly enough – you will not be able to make calls or connect to the web.
ESIMS can also be exposed by malicious software running on your phone or tablet, often delivered via a link in a message or email on which you are deceived. This can open your device and its ESIM to unauthorized access, which could then lead to hackers to be able to interfere with your communications.
The usual security advice applies here. Beware of phishing attempts, for example, and think twice to follow the links, unless you are absolutely sure they are authentic. If you have any doubts, try to contact the message (apparent) of the message to return, whether it is a family of the family or the bank with which you do business.
Any account that you have with an ESIM operator or supplier can be hacked if someone else has access to your connection identification information. As always, make sure that you use long passwords that are difficult to guess and activate two-factor authentication if it is proposed (this is usually the case), so an additional code is necessary to connect to a new device.
Keep your phone’s software and applications up to date as much as you can, as it will strengthen the integrated protection that protects your ESIM. In addition, keep your phone well protected thanks to biometric safety on the lock screen and a long spindle, which makes any more difficult for anyone to access your handset.
