Three calls to a working eSIM

Find a plan, pay for it, collect the eSIM. Everything else in the walkthrough builds on these three requests.

Nobody should need permission to get online

In much of the world a SIM card means registering a national ID, and paying for it means a bank account you may not be allowed to keep. Those are two gates on being connected, and either can be shut — by a government, a bank, or a border. Tizon takes both out of the path.

  • No ID to get online

    Buying an eSIM through Tizon carries no personal data. There is no field in the API for a name, an ID or a date of birth: a purchase is an offer and a payment. Read the spec and check.

    offer_id + payment_source

  • No bank to pay for it

    Lightning and stablecoins settle every purchase. Unbanked, debanked, or living under capital controls, the payment still goes through.

    payment_source: lightning

  • No capital to sell it

    No float and no minimum balance, so a reseller anywhere can start with nothing in hand and keep 15% to 20% of every order, paid in bitcoin.

    POST /v1/revenue/payouts

  • No border to cross

    An eSIM works where someone already is, with no local contract and no local registration. For people who move — by choice or not — that is the difference between connected and cut off.

    GET /v1/offers?country=…

What this does not do

An eSIM rides a partner mobile network, so a full national internet shutdown still stops it, and an eSIM is not a VPN — it gives no privacy from the carrier itself. Tizon removes the identity and payment gates on getting connected. It does not replace the network.

You keep a share of every order

Commission accrues to your Revenue Centre as each order is fulfilled. There is nothing to claim, invoice or reconcile at month end: spend it as wallet credit that buys more eSIMs, or take it out over Lightning.

How earnings work
commission 30-day volume
  1. Standard under $5,000 15%
  2. Growth $5,000 to $50,000 17.5%
  3. Scale above $50,000 20%

Your rate follows your last 30 days of volume. Nobody at Tizon sets it.

    Offer data for trips abroad and top-ups at home as an in-app purchase, next to cards and transfers.

    GET /v1/offers?category=esim

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.
