Nevertheless, in the unfortunate event that your bank account information is stored on the SIM card, and if someone were to gain access to and possess the knowledge to read its contents, your financial security could be jeopardized. To safeguard yourself from potential data theft, it is advisable to keep your SIM card secure and in your possession.

Other data stored by this SIM card

If you value your privacy and are concerned about the security of your personal information, what you’re about to learn may make you uneasy. Beyond the obvious bank account details, mobile phone number, and name stored on the SIM card, there are additional data that could be at risk.

Among these data are details such as your contracted operator, IMEI code, country code, and location information associated with the card. All of this information must fit within the 512 KB storage capacity of the SIM card. It’s important to be aware that the theft of SIM card information, known as SIM-Swapping or SIM-Hacking, is a real threat, and it’s possible for all this data to fall into the wrong hands.

Considering the extent of data that your SIM card can retain, it’s advisable to think twice before discarding it and instead keep it in a secure place where you have control over it. If you have set a PIN number for your SIM card, it provides an added layer of protection and can offer some peace of mind. In the event that you misplace the SIM card, it would be challenging for unauthorized individuals to access the information. Conversely, relying solely on a pattern lock or similar security measure when turning off or restarting your phone poses significant risks to your data security.
