The Vietnam Visa Run, Explained: Routes, Costs and Mistakes (2026)
Every 90 days, half the nomads in Da Nang do the same dance: fly out, apply, fly back. Here is the 2026 version of the Vietnam visa run, without the guesswork.
Key takeaways
- Vietnam's e-visa allows up to 90 days, single or multiple entry, open to all nationalities, applied for online.
- E-visas currently cannot be extended in-country, which is why the visa run exists: exit, apply fresh, re-enter.
- Processing officially takes 3 to 5 working days, so apply before you travel, not at the border.
- Popular runs: Bangkok, Kuala Lumpur or Singapore by air; Phnom Penh or Vientiane by land from the south and north.
Which network you get, and what it really costs
In Vietnam the Fizen eSIM roams on Viettel Mobile (4G). Vietnam is sold inside the South-Eastern Asia plan, which covers 18 countries. At 128 kbps you can still send messages and load map tiles, but not hold a video call.
| Plan | Days | Price | Per day | Per GB | After the high-speed data |

Prices and carrier read from the Fizen catalogue on 23 September 2026. Data only, no calls or SMS.
Prices are before the welcome credit. A new user who opens the eSIM tab in the Fizen app for the first time gets US$10 of eSIM credit automatically, with no code, valid for 12 months. The app shows how much of it comes off your order. Paying by card on the web works too, but the credit only applies in the app.
Vietnam gives you 90 days on an e-visa and no way to extend it from inside the country. So every quarter, a small migration happens: nomads and long-stayers leave, spend a weekend somewhere nearby, and come back on a fresh visa. Done right it is a routine errand with a bonus holiday attached. Done wrong it is a refused boarding and a very expensive lesson.
How the cycle works
- Apply for the e-visa online at the official government portal, up to 90 days, single or multiple entry, per Emerhub's 2026 guide.
- Live your 90 days. Set a reminder for day 75, not day 88.
- Apply for the NEXT e-visa while still in Vietnam, since processing takes 3 to 5 working days.
- Exit before expiry, wait for approval if it has not landed yet, and re-enter on the new visa.
Choosing your run: the honest comparison
| Route | Why people pick it | Notes |
|---|---|---|
| Bangkok (air) | Cheap flights from all three hubs, huge onward connections | The default. Fly out of Hanoi, Da Nang or Saigon |
| Kuala Lumpur (air) | Often the cheapest fares, easy airport | Great from Saigon and Da Nang |
| Singapore (air) | Most reliable, most expensive | When you want zero drama |
| Phnom Penh (land/air) | Closest to Saigon, bus option exists | Land crossing at Moc Bai works but queues vary |
| Vientiane (land/air) | Closest to Hanoi | Quieter, fewer flights, plan around them |
The mistakes that actually bite
- Applying at the last minute. The 3 to 5 day processing window is real, and weekends do not count.
- Typos in the passport number or entry checkpoint on the application. The visa is checked against both.
- Booking a same-day turnaround. Some travellers do it without issue, but a same-day re-entry invites questions. An overnight stay reads better.
- Forgetting the entry port matters: your e-visa lists where you will enter, so re-enter through a listed checkpoint.
- Letting your passport drop under six months validity mid-cycle.
The money side of a visa run
A run touches three currencies in 48 hours: dong on the way out, baht or ringgit or riel in the middle, dong again on re-entry. Cards get declined abroad at the worst moments, and airport exchange rates are the worst in any country. This is where holding USDT quietly wins: pay by Fizen card or QR in Vietnam, spend the same balance in Bangkok or KL, and skip the exchange counter entirely. One balance, every leg of the run.
Stay connected across the border
Your Vietnamese SIM goes quiet the moment you cross. Set up an eSIM that covers both countries before the trip: install at home on Wi-Fi, and you land in Bangkok with data for Grab and your boarding passes. Plans are on Fizen eSIM pricing, and setup steps are in the eSIM guide.
