The short answer
Bangkok, then a flight to Hanoi or Ho Chi Minh City, then home from Da Nang: that is the Thailand and Vietnam trip I priced. I read six regional plans on 25 October 2026 for three days, a week, two weeks and a month, checked the fine print on unlimited, and added up Ringo Light's two country plans. For two weeks or more across both, I would buy Ringo Light.
A single eSIM for Thailand and Vietnam, unlimited data at full speed, 2 weeks at $34.99 or 30 days at $59.99, nothing renews. Airalo asks $49 for 15 days and $73.50 for the month.
A long weekend in Bangkok and a quick trip north: 3 days of unlimited at $11.50, with 3 GB a day at full speed, then 1 Mbps.
Maps and messaging only: 10 GB for 30 days at $21 and 20 GB for 45 days at $35 (on sale, regular $40).
A week on both sides of the border with 25 GB at full speed for $25, then 2 Mbps. 20 GB a month for $19 if you are happy with a plan that renews.
Prices read on 25 October 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.

The prices, charted
Asia regional plans that cover both, US dollars, 25 October 2026. Ringo Light sells 2 weeks, the others 15 days. Ubigi's 15 days is 30 GB at full speed, then 2 Mbps. Nomad sells no two-week unlimited; its longest is 10 days at $29.
The 30-day regional plan at each brand. Ubigi's month is 60 GB at full speed, then 2 Mbps. Nomad sells no 30-day unlimited.
Holafly sells no buckets. Ringo Light sells no bucket either: its 2 weeks is unlimited, so it lasts 2 weeks, not 30 days.

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 Thailand and Vietnam, and what your phone needs for it
Eight places that tend to fill a trip from Bangkok to Vietnam, four in each country, with the one thing your data does for you at each. One Asia eSIM works at every stop.
One plan for both countries: Ringo Light
Thailand to Vietnam is a one-way flight, often a cheap one, and the last thing you want on arrival is to find a new eSIM. With a regional plan you install once and the phone just picks up a network in Hanoi. With two country eSIMs you buy twice and swap in the airport queue.
The Asia plan from Ringo Light costs $34.99 for 2 weeks and $59.99 for 30 days, and nothing renews. For roughly two weeks of unlimited on a regional plan I read Ubigi at $45 for a fixed 30 GB at full speed, Airalo at $49, Holafly at $51.50 and Saily at $54.99. For a month the rivals ask $66 to $86.99.
Buying Ringo Light's country plans separately costs more for this route. Thailand's 2 weeks is $22.99 and Vietnam's $22.99 on their own pages, $45.98 together, against $34.99 for the Asia trip that covers both. For a month, Thailand's 30 days is $32.99 and Vietnam's $42.99, $75.98 together, against $59.99.
If your trip is nearly all in one of the two, say a month in Chiang Mai with a few days in Hanoi, then Thailand's own 30 days at $32.99 is the cheaper plan and I would check that page first.
Which plans cover both countries
Ringo Light covers both: Thailand and Vietnam are two of its 20 countries, on the same eSIM and the same price.
The other five brands I can only describe by the parent's numbers: Airalo 18 countries, Holafly 16, Saily 22, Nomad 14 and Ubigi 17, with the few notable exclusions the parent lists, none of them Thailand or Vietnam. I could not confirm Thailand and Vietnam one by one on each rival's list on the day, so I would open the list for the brand you pick.
If you want a data bucket: Nomad or Airalo
- Nomad, $21 for 10 GB. The cheapest 10 GB on its 14-country APAC plan, and 20 GB for 45 days at $35 (on sale, regular $40). Fine for maps, rides and messages.
- Airalo, $25 for 10 GB. Asialink, 18 countries, 20 GB for 30 days at $39, buckets from $4 for 1 GB.
- Ubigi, $28 for 10 GB. Best Asia, 17 countries. Its 20 GB for $19 is a monthly plan that renews until you stop it.
- Saily, $35.99 for 10 GB. Asia and Oceania, 22 countries, no 20 GB bucket on its listing. Read on saily.com, 25 October 2026.
- ✓Ringo Light, no buckets. Its 2 weeks is unlimited for $34.99 and its 30 days unlimited for $59.99. For a fixed 10 GB across Asia, Nomad and Airalo are cheaper, and for 20 GB so are Nomad, Airalo and Ubigi's monthly plan. I would buy Ringo Light for unlimited, not for a bucket.
What Ringo Light is
I write for Ringo, and Ringo Light is its own data eSIM, so read this with that in mind. It is sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Asia it sells two trips across 20 countries, Thailand and Vietnam among them, both unlimited data at full speed: 2 weeks at $34.99 and 30 days at $59.99. Nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
The card to buy it is further up this page, just after the side-by-side table.
Pick by trip
I would buy Airalo unlimited, 3 days, $11.50. Ringo Light sells no 3 days on the Asia plan.
I would buy Ubigi's week with 25 GB at full speed for $25, or Airalo at $26 for 7 days. Ringo Light has no week; its 2 weeks is $34.99.
I would buy Ringo Light unlimited, 2 weeks, $34.99, less than any rival charges for two weeks.
I would buy Ringo Light unlimited, 30 days, $59.99.
I would buy Nomad 10 GB for 30 days at $21, if its 14 countries include both of yours.
None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
