Before you start
You'll need a carrier-unlocked, eSIM-compatible phone and a Wi-Fi connection. Install your eSIM at home, on your own Wi-Fi, a day or two before you travel — never after you've landed and lost connectivity.
Step 1 — Buy your plan
Choose your destination on yeloesim, pick a data plan, and check out. Your eSIM QR code and setup instructions arrive by email within seconds.
Step 2 — Scan the QR code
On iPhone, open Settings → Mobile Data → Add eSIM → Use QR Code. On Android, open Settings → Network & Internet → SIMs → Add eSIM. Point your camera at the QR code from the email and confirm.
Step 3 — Turn it on when you land
Label the eSIM so it's easy to find, keep your home SIM as your default for calls and texts, then switch mobile data to the eSIM and enable data roaming for it once you arrive. You're online — no SIM swap, no shop queue.
Troubleshooting
If the eSIM doesn't connect, toggle Airplane Mode on and off, or restart your phone. Still stuck? Our live chat is open 24/7, and every plan is covered by our money-back guarantee if it can't be installed.
