What is eSIM?

An eSIM ( Embedded Sim card)is essentially a digital equivalent of the traditional physical plastic SIM card found in most phones.

  • A physical SIM card is a small piece of plastic with a chip on it. It contains your mobile number and details of your mobile plan (Example: data, SMS, and voice call allowances).
  • An eSIM, on the other hand, is a digital version of this information stored directly within your phone/device’s hardware.
