The short answer
Six travel eSIMs sell a Vietnam plan and get most of the traffic for this search. I priced all six on the same day, for two weeks from Hanoi down to Ho Chi Minh City and for a month of remote work in Da Nang, and I read the fine print on unlimited. Here is where each one wins.
Unlimited data at full speed for 2 weeks at $22.99 or 30 days at $42.99, nothing renews. Airalo asks $48 for 15 days and $69 for the month.
10 GB for 30 days at $13 on VNPT with 5G. Ubigi sells no unlimited plan for Vietnam.
Unlimited for 3 days at $11.50 on its Xin Chao plan, and buckets from $4 for 1 GB.
Days, not gigabytes, no daily cap stated for your own phone, on Vinaphone. $27.50 for a week; sharing limited to 1 GB a day.
Prices read on 10 November 2026: Airalo, Holafly, Saily, Nomad, Ubigi on their own sites or listings, Ringo Light from its catalogue. All in US dollars unless stated. Treat every number as a snapshot.

We sell data eSIMs for now to fund the full Ringo service. Ringo is self funded. Every plan bought here pays for the build of one plan that works everywhere.
Want to keep your own number abroad?
That is the full Ringo service: one plan that works everywhere, with your own number included.
It is a separate product from Ringo Light and it is still being built, so it is not on sale yet. Join the waitlist to hear when it opens.
What to do in Vietnam, and what your phone needs for it
Eight places most first trips include, from Hanoi in the north to the Mekong Delta in the south, with the one thing your data does for you at each. The main towns and the tourist routes between them have good 4G, and 5G in the big cities.
If you want unlimited for two weeks or a month: Ringo Light
Vietnam is a long, thin country and most people cover it over two weeks or more. For 15 days, Airalo asks $48, Saily $48.99 and Holafly $51.50. For a month, $69, $71.99 and $76.50. Nomad stops at 10 days for $33, and Ubigi sells no unlimited plan here. Ringo Light charges $22.99 for 2 weeks and $42.99 for 30 days, nothing renews. For a trip this long, that is the row I would buy.
I read what unlimited means before I look at any price. Airalo gives 3 GB a day at full speed, then 1 Mbps. Saily gives 5 GB a day, Nomad 2 GB. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Ringo Light is unlimited data at full speed for 7 days, 2 weeks or 30 days.
For 3 days I would skip Ringo Light, which sells no 3-day plan. Airalo sells 3 days of unlimited at $11.50, though Ringo Light's 7 days at $8.99 costs less than that.
If you want a data bucket: Ubigi
- Ubigi, $13 for 10 GB. The cheapest 10 GB for 30 days, on VNPT with 5G. Its 20 GB is a monthly plan that renews.
- Nomad, $17 for 10 GB. On Vietnamobile, MobiFone and Vinaphone, 20 GB for $25, and 50 GB for $39 if you work online all month.
- Saily, $17.99 for 10 GB. 20 GB at $28.99.
- Airalo, $18 for 10 GB. Its Xin Chao plan rides VNPT. 20 GB for $29.
- ✓Ringo Light, no buckets. The Ringo Light 2 weeks is unlimited for $22.99 and the 30 days unlimited for $42.99. For 10 GB that lasts a month, Ubigi at $13 is the better buy, and Nomad sells 20 GB for $25, Saily and Airalo for about $29. I would rather you read that here than at checkout.

Frequently asked questions
How we compared, and our sources
Airalo, Holafly, Saily, Nomad, Ubigi, Ringo Light
We priced Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Vietnam on 10 November 2026, all on the same day, in US dollars.

We compare the trips people actually book: a week, two weeks and a month of unlimited data, and a 10 GB bucket. We read each brand's fair use and speed rules and quote them as the brands state them. We did not run speed tests, so this page makes no speed claims for any brand.
Ringo Light is our own product. We put it in the table on the same terms as everyone else, and where a rival is the better buy the page says so.
Left out: Maya Mobile. We could not read its own prices for this country on the day, so it stays out rather than being guessed.
