iPhone
Settings → Cellular (or Mobile Data) → look for Add eSIM / Add Cellular Plan. Or dial *#06# — if an EID appears, eSIM is supported. Models from iPhone XS / XR and newer generally work.
Setup guide
Get started
Two checks before you buy: confirm your phone supports eSIM, then install with our QR when it arrives.
How to check if your phone supports eSIM
Android
Settings → Network & internet → SIMs (or Mobile network) → Add eSIM / Download a SIM. Or dial *#06# for an EID. Samsung Galaxy S20+, Google Pixel 3+, and many recent flagships support eSIM — menus vary by brand.
Carrier-locked phones or some regional models may block eSIM. If you only see physical SIM options, do not buy until you confirm with your device maker.
How to install our eSIM
Best practice: install on Wi‑Fi 2–3 hours before departure. Keep your home SIM active for OTPs.
Step 1
Open your QR email
Open the QR email from eSim For Vietnam. Save or screenshot the QR if needed.
Step 2
Scan to add eSIM
iPhone: Settings → Cellular → Add eSIM → Use QR Code. Android: Settings → SIMs → Add eSIM → Scan QR.
Step 3
Label the Vietnam line
Label the line “Vietnam”. After landing, turn on Mobile Data for that line. Keep Data Roaming OFF — this is a local Viettel eSIM, not a roaming plan.
Step 4
Mobile data ON, roaming OFF
After landing, disable Airplane mode. Select the Vietnam eSIM for mobile data, turn Mobile Data ON, and keep Data Roaming OFF. Wait 5–10 minutes for Viettel to register.
Do not delete the eSIM if something fails — contact support first. Deleting may consume the profile.
Manual setup (if QR scan fails)
Your email also includes SM-DP+ / activation details for iPhone and the full LPA string for Android. Enter them under “Enter details manually”.
