An eSIM (embedded SIM) is a digital SIM card built directly into your phone. Instead of swapping a plastic chip, you scan a QR code and a new line — with its own local phone number — is installed in seconds.

Why use an eSIM number

  • Receive SMS and calls on a real local number, without exposing your main one.
  • Stay anonymous — no passport, no ID, no verification.
  • Keep your main SIM — the eSIM runs alongside it.
