How secure is an eSIM?

eSIMs offer some great security advantages over physical SIM cards:

  • Embedded nature – Being soldered into the device’s hardware makes eSIMs less vulnerable to physical theft or tampering compared to removable SIM cards.
  • Remote provisioning – Over-the-air activation removes the need to carry a SIM card to the carrier store for provisioning. This reduces the risk of interception or cloning of the SIM.
  • Encryption – eSIM profiles use robust encryption for the subscription information and communication with cellular networks. This prevents unauthorized access.
  • No cloning – The unique pairing of eSIM to device makes the profiles harder to copy or clone than standard SIM cards.

So in summary, eSIMs offer improved physical security and protection against cloning.
