Vietnam travel tips
- Most Vietnam trips cover a lot of ground: Hanoi and Ha Long Bay in the north, Hoi An in the middle, and Ho Chi Minh City and the Mekong in the south. That usually means two to four weeks, so look at price per GB and at 15- to 30-day plans rather than the cheapest short plan.
- Travellers tend to use more data in Vietnam than they expect. Ride-hailing apps such as Grab, translation apps (including camera translation of menus and signs), maps and messaging all add up. If you're unsure, plan on medium use of about 1 GB a day and size up from there.
- Long bus and train trips between cities can have weaker signal on some stretches. Download offline maps and any translation language packs before you travel.
- Most travel eSIMs are data-only. Keep your Australian SIM switched on for calls and SMS codes, with its data roaming off, and use the eSIM for everything else. Install it at home on Wi-Fi before you fly.
Frequently asked questions
What is the best eSIM for Vietnam?
As of 14 Nov 2026, the cheapest Vietnam eSIM per GB we found is Nomad's 50 GB plan at A$56.74 for 30 days (A$1.13/GB). As of 14 Nov 2026, the best 1-week Vietnam eSIM is Airalo's 3 GB plan at A$12.00 for 7 days. As of 14 Nov 2026, the cheapest unlimited Vietnam eSIM is Maya Mobile's Unlimited plan at US$49.99 (≈ A$73.68) for 30 days (≈ A$2.46/day).
How much data do I need for 2 weeks in Vietnam?
At medium use of about 1 GB a day, you'd want around 14 GB. If you use ride-hailing, translation and maps all day, or share a hotspot, plan for more. The calculator below works out the cheapest plan for the amount you pick.
Can I use Grab with a travel eSIM in Vietnam?
Yes. Grab works over mobile data, so a data-only eSIM is enough to book rides and food. Keep your Australian SIM on if you need SMS codes for payment or sign-in.
Should I get unlimited or fixed GB for Vietnam?
If you're a heavy user or travelling for several weeks, unlimited can be simpler. If you mostly use maps and messaging, a fixed-GB plan is often cheaper. Compare both in the table above, and check unlimited plans for fair-use limits.
Does a travel eSIM give me a Vietnamese phone number?
Usually not. Most travel eSIMs are data-only. You can still use WhatsApp, Zalo and similar apps for calls and messages over data.
