eSIM explained

Why an eSIM? Same network, no plastic.

An eSIM does exactly what your regular SIM card does — it just lives as software on your phone. Less hassle, lower costs.

  • Online in 2 minutes

    Scan the QR code and your bundle is on your phone. No waiting for a card in the mail.

  • No roaming surprises

    The price is fixed before you order. No extra charges, nothing quietly ticking on.

  • Keep your own number

    The eSIM works alongside your current SIM. You stay reachable on your own number.

  • Nothing to swap

    No ejector pin, no loose card to lose. Switching bundles takes one tap.
