New to eSIM? Start here.

An eSIM is a SIM card that’s downloaded instead of inserted. Your code never touches the phone’s hardware: you give your user a string, and their phone does the rest.

  1. 01

    Your backend buys a plan

    POST /v1/quotes

  2. 02

    Tizon returns an eSIM profile

    iccid + lpa

  3. 03

    Your app shows it

    QR code or install link

  4. 04

    The phone downloads it

    from the operator’s server

  5. 05

    Your user is online

    on a local network

Five terms you’ll see

eSIM
A SIM profile stored on a chip built into the phone (the eUICC), installed over the internet instead of as a plastic card. Most travel eSIMs are data-only: no phone number.
ICCID
The eSIM’s unique number, 18 to 22 digits. Store it against your user: top-ups target it.
LPA string
LPA:1$<SM-DP+ address>$<activation code>. Everything the phone needs to install the profile. Render it as a QR code.
SM-DP+
The operator’s server the phone downloads the profile from.
Activation code
The last part of the LPA string, for users who type the details in by hand.

Before you ship

  • The phone must support eSIM and be carrier-unlocked. Most flagship phones from 2018 onwards do.
  • Installing needs an internet connection, so let users install before they travel.
  • A profile usually installs once. Show the LPA only to the user who bought it.

Tizon is a prepayment technology API, not a telco. It’s built to make it easy for mobile and web app builders to offer eSIMs and top-ups to their customers. No prefunded account or minimum balance is needed: you settle in stablecoins, Lightning or local bank transfers. We support global, regional and local eSIMs.
