TL;DR: On iPhone, open Settings → Mobile Data → Add eSIM → Use QR Code, scan your RoameSIM QR on Wi‑Fi before your flight, then after landing enable the line, turn on data roaming, and set it as your mobile data line.
What you need
- iPhone XS or newer, carrier-unlocked
- RoameSIM QR code (email or order tracking link)
- Stable Wi‑Fi for installation
Step 1: Purchase your plan
Choose a destination on RoameSIM, complete guest checkout, and open the QR code from your email within minutes.
Step 2: Add eSIM with QR code
- Open Settings → Mobile Data → Add eSIM (or Add Mobile Plan).
- Tap Use QR Code and scan the RoameSIM QR.
- Label the plan (e.g. “Travel”) and complete setup.
If your iPhone offers a direct install link in the email, you may tap it instead of scanning.
Step 3: Manual install (if QR fails)
- Settings → Mobile Data → Add eSIM → Enter Details Manually.
- Enter the SM-DP+ address and activation code from your RoameSIM email.
Step 4: Before the flight
You can leave the new line installed but disabled until arrival. Keep your home SIM active for calls and OTPs. Read benefits of dual SIM for travel.
Step 5: After landing
- Settings → Mobile Data → enable your RoameSIM line.
- Mobile Data → select RoameSIM as Mobile Data line.
- On the RoameSIM line → Data Roaming ON.
- Turn off mobile data on your home line to avoid roaming charges.
Step 6: Verify connection
You should see signal bars and LTE/5G on the eSIM line. Test maps or browser. No data? Follow our eSIM troubleshooting guide.

Frequently Asked Questions
Which iPhones support eSIM?
iPhone XS, XR, and all newer models support eSIM. iPhone 14 and later US models may be eSIM-only. Your device must be carrier-unlocked for RoameSIM travel plans.
Can I install eSIM on iPhone before traveling?
Yes — recommended. Connect to Wi‑Fi at home, scan the QR from your RoameSIM email, and leave the line off until you land. Data typically starts when you connect in the destination country.
How many eSIMs can iPhone store?
Recent iPhones store multiple eSIM profiles but usually allow two active lines at once (one physical + one eSIM, or two eSIMs on eSIM-only models).
What if QR scan fails on iPhone?
Use manual installation: SM-DP+ address and activation code from the same email. Ensure strong Wi‑Fi and update iOS. Do not scan the same QR twice on different devices if the plan is single-use.
Do I turn on data roaming?
Yes — after landing, enable Data Roaming on the RoameSIM line (Settings → Mobile Data → your plan → Data Roaming).
