No data plan of this length holds that much, so an unlimited plan is the safer choice.
Estimates for typical use. HD video and large uploads use more.
Your 7 days starts at your first connection abroad, not when you pay — and it runs as a rolling window. Connect at 01:00 and it lasts until 01:00 on day 8, not to midnight.
Does your phone support an eSIM?
Dial *#06# on your keypad. If the panel that opens lists an EID, your phone is eSIM-ready. It works on iPhone and Android, takes about ten seconds, and nothing leaves your device.
Not listed? Dial *#06# — if an EID number appears, your phone supports eSIM. See the full list
No EID? The phone takes a physical SIM only, and a travel eSIM will not work on it. If the EID is there but your handset came from a carrier, check it is not network-locked before you buy.
Installed before you board
Your QR arrives by email the moment payment clears. Install on the sofa, land in Hanoi connected.
Choose unlimited, fixed data, or data with calls. The price you see is the price you pay.
It lands in your inbox instantly. Install the profile at home over Wi-Fi and leave it dormant.
The plan activates the moment you connect in Vietnam — validity starts then, not at purchase.
Your eSIM never expires
Only a plan has a validity. The eSIM stays on your phone, so whenever you need data again you add a new plan to the same eSIM.
- No new QR codeA top-up goes onto the eSIM you already installed. Nothing to scan, nothing to reinstall.
- Top up for your next tripMost eSIMs take plans for other destinations too, so one eSIM can travel with you.
- Plan expired? Add anotherWhen a plan runs out, the eSIM stays. Add a new plan and carry on with the same profile.
Key features
Vietnam eSIM: seamless connectivity
Vietnam rewards travellers who move — Ha Long Bay one day, Hoi An the next. Getting between them, finding the places that are not in the guidebook and keeping everyone at home updated all rests on a connection that simply works, which is what the ZetSIM Vietnam eSIM is built for.
Buy before you fly, scan once and the profile sits dormant until you land in Hanoi. Validity starts on first connection, tethering is included, and the same eSIM can be topped up for your next trip anywhere in our 200+ country footprint.
Technical details
Unlimited plans carry 2 GB of high-speed data per day, then unlimited data at 256 kbps. The counter resets on a 24-hour timer from your first connection — activate at 10 AM and fresh high-speed data lands at 10 AM daily.
Mobile networks in Vietnam
