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 $50.50. For a month, $69, $71.99 and $73.90. Nomad stops at 10 days for $33, and Ubigi sells no unlimited plan here. Ringo Light charges $18.99 for 2 weeks and $34.99 for 30 days, one payment each, nothing renews.
Read what unlimited means before you pick. 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 has no speed cap: the 2 weeks starts with 10 GB and the 30 days with 20 GB, and when you have used 80% we add 10 GB once and charge the $18.99 top-up. A heavy two weeks with us costs $37.98, a heavy month $53.98, still under every rival for the month.
For a short stay, Ringo Light sells no 3-day or 7-day plan. Airalo sells 3 days of unlimited at $11.50.
Ubigi, $12.90 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, and 50 GB for $39 if you work online all month.
Saily, $17.99 for 10 GB. 20 GB at $28.99. Its listing is from July; saily.com would not load for us.
Airalo, $18 for 10 GB. Its Xin Chao plan rides VNPT. 20 GB for $29.
Ringo Light, no buckets. Our 2 weeks starts with 10 GB for $18.99 and our 30 days with 20 GB for $34.99. For 10 GB that lasts a month, Ubigi at $12.90 is the better buy, and Saily and Airalo sell 20 GB for about $29. We would rather you read that here than at checkout.
Ringo Light is our own data eSIM, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Vietnam it sells two trips, both unlimited data at full speed with no speed cap: 2 weeks at $18.99, starting with 10 GB, and 30 days at $34.99, starting with 20 GB. Each adds 10 GB once at 80%, charged at $18.99. One payment, nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
A plan over $10 makes you a Ringo Pioneer with €5 off the full Ringo at launch. The card to buy it is just below this article.
A few days in Hanoi or Ho Chi Minh City. Airalo unlimited, 3 days, $11.50. Ringo Light sells no 3 days.
Two weeks from north to south. Ringo Light unlimited, 2 weeks, $18.99, less than any rival charges for one week of unlimited.
Two weeks, light use, budget first. Ubigi 10 GB for 30 days at $12.90.
A month of remote work in Da Nang. Ringo Light unlimited, 30 days, $34.99, starting with 20 GB and adding 10 GB once for $18.99. Nomad 50 GB at $39 if you know you will use a lot.
You need your own number to keep ringing. None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
We priced Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Vietnam on 27 September 2026, all on the same day, in US dollars. Each rival's price comes from its own website where it showed dollars, otherwise from an esimdb.com listing, and every source and its date is listed below. Ringo Light's prices come from the catalogue our checkout charges.
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.

Airalo, Holafly and Ubigi ride VNPT, also called Vinaphone. Nomad lists Vietnamobile, MobiFone and Vinaphone. Viettel, the largest network, is not named by any of the brands we priced.
Every brand has a limit somewhere. Airalo slows you after 3 GB a day, Saily after 5 GB, Nomad after 2 GB. Holafly states no daily cap for your own phone. Ringo Light has no speed cap: it starts with 10 or 20 GB and adds 10 GB once at 80%, charged.
Viettel and Vinaphone sell tourist SIMs at Noi Bai and Tan Son Nhat airports, often cheaper per gigabyte, but you queue with your passport after a long flight. A travel eSIM is installed before you fly and works the moment you land.
