eSIMs: A Convenient but Risky Alternative to Traditional SIM Cards

eSIMs: A Convenient but Risky Alternative to Traditional SIM Cards

Got a new mobile phone? Noticed it no longer needs a SIM card?

An eSIM is a small chip that's built into your phone and lets you activate your mobile service without needing a physical SIM card. It's a cool feature that makes it easy to switch between different carriers. But, there's a catch! eSIMs can be hacked, and a bad guy can steal it to access your private accounts. They can even use it to pretend to be you and bypass two-factor authentication.

Here are five ways to protect yourself from eSIM hacking:

  1. Set a Strong PIN: Set a strong PIN for your eSIM to prevent unauthorized access.

  2. Use a VPN: Use a Virtual Private Network (VPN) when browsing the internet to encrypt your data and protect your online activities.

  3. Keep Your Software Up-to-Date: Regularly update your device software to ensure that security patches are installed, and vulnerabilities are fixed.

  4. Be Careful with Sensitive Information: Be cautious about sharing sensitive information online or over the phone, especially if you're not sure who you're talking to.

  5. Enable Two-Factor Authentication: Enable two-factor authentication for all your online accounts that support it. Avoid using SMS-based verification codes and instead use an authenticator app or a physical security key to authenticate your login attempts.
