Vietnam eSIM.
Hanoi's Old Quarter to Ha Long Bay and Phu Quoc's shores — connected all the way.
Every plan: QR by email in minutes · data-only, keep your number · days start on first connection · top up anytime · the total shown is the whole bill. What's included →
Unlimited plans run at full speed up to a daily fair-use allowance, then at reduced speed until the allowance resets the next day — you're never cut off. Every plan is prepaid: the checkout total is the whole bill, and we never add overage charges.
Hotspot support varies by plan and destination — where it's available for your plan in Vietnam, it's shown in the plan details before you pay.
The Vietnam eSIM guide.
Vietnam stretches over a thousand miles from the karst mountains of the north to the Mekong Delta in the south, so most holidays here are really a string of journeys. Data keeps it all moving — booking Grab rides, translating menus, mapping the Old Quarter's tangled alleys and video-calling home from the beach.
How it works on the day
Install your eSIM before you fly, then switch it on as you land at Hanoi's Noi Bai or Ho Chi Minh City's Tan Son Nhat. It connects to Viettel or VinaPhone automatically — no SIM kiosk, no passport paperwork, and your home number stays live for texts.
Choosing your days
Two weeks is the classic north-to-south run; add days for Sapa trekking or a Phu Quoc wind-down. Pick a plan that spans the whole trip, as the per-day cost drops the longer you stay.
Discover Vietnam.
The short version.
A travel eSIM is data only. It sits next to your home SIM, so your number, texts and WhatsApp carry on as normal. Pick unlimited, priced per day, or a fixed bundle of GB if it's mostly maps and messages. Install it on Wi-Fi before you fly — the days only start once it first connects in Vietnam, and it finds a partner network on its own.
