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.
- 01
Your backend buys a plan

Tizon returns an eSIM profile
iccid+lpa - 03
Your app shows it
QR code or install link

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.
