Holafly vs Saily in one paragraph
Saily is cheaper than Holafly for Vietnam at every length both sell: $26.99 against $27.50 for a week, $48.99 against $51.50 for 15 days and $71.99 against $76.50 for 30 days. Holafly is the only one of the two with a 3-day plan, at $11.90. Holafly gives you the simpler product: unlimited days with no stated daily cap, on Vinaphone, with an optional app. Saily gives you more choice, buckets of 10 GB and 20 GB as well as unlimited, but its unlimited slows after 5 GB a day, you need its app, and it does not name the Vietnamese network it uses. Pick Saily if you want a bucket or the lower price at any length. Pick Holafly for a 3-day trip, or if you never want to think about a daily cap. If the trip is two weeks or a month and you want unlimited, neither is the cheapest: Ringo Light sells 2 weeks at $22.99 and 30 days at $42.99, unlimited data at full speed.
Price: the same trip at each
Priced on 25 October 2026, in US dollars. For 3 days of unlimited, Holafly asks $11.90; Saily sells no 3-day plan. For a week, $27.50 at Holafly and $26.99 at Saily. For 15 days, $51.50 at Holafly and $48.99 at Saily. For 30 days, $76.50 at Holafly and $71.99 at Saily. So Saily wins every length both sell, by 51 cents, $2.51 and $4.51; only Holafly sells 3 days.
Ringo Light sells two trips for Vietnam: 2 weeks at $22.99 and 30 days at $42.99. The 2 weeks costs $26.00 less than Saily's 15 days at $48.99 and $28.51 less than Holafly's at $51.50. It also costs less than either one's week: $4.00 below Saily's $26.99 and $4.51 below Holafly's $27.50. The 30 days costs $29.00 less than Saily's $71.99 and $33.51 less than Holafly's $76.50. Ringo Light sells no 3-day or 7-day plan; for exactly a week, you buy its 2 weeks at $22.99 and have a week left over.
For a fixed amount of data, Saily is the only one of the three that sells it: 10 GB for 30 days at $17.99, 20 GB at $28.99. Holafly sells no buckets. Ringo Light sells no buckets either. If 10 GB is all you need, Saily is cheaper than Ringo Light's $22.99, and we would rather you read that here than at checkout.
What unlimited means at each
Saily's unlimited for Vietnam gives 5 GB a day at full speed, then slows you for the rest of the day. That is enough for maps, messages and several hours of video; a full day of HD streaming or a big download will hit it. Holafly states no daily cap for your own phone and limits hotspot sharing to 1 GB a day, so Holafly is the one to pick between the two if you refuse any cap on your own screen, and Saily is the one with more headroom for sharing to a laptop, up to its 5 GB. Ringo Light is unlimited data at full speed for the whole 2 weeks or 30 days. Fair use policy, see Terms.
Networks and coverage in Vietnam
Holafly rides Vinaphone, also called VNPT. Saily does not name its Vietnamese network. Ringo Light rides a local partner network. Viettel, the largest network in Vietnam, is not named by any of the brands in the full comparison. For Hanoi, Hoi An, Da Nang and Ho Chi Minh City, the main towns and the routes between them have good 4G, and 5G in the big cities.
Installation, app and support
Saily needs its app: you buy, install and top up inside it. Holafly has an optional app and also installs from a QR code. Ringo Light needs no app; the eSIM arrives by email in seconds and installs in one scan, and support is by email. Whichever you pick, install it at home before you fly and switch it on for data when you land at Noi Bai or Tan Son Nhat.
The cheaper third option: Ringo Light
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: 2 weeks at $22.99 and 30 days at $42.99. One payment, nothing renews, no app.
What it does not do: no buckets, no 3-day or 7-day plan, no phone number, data only. Calls go over apps that use data. If you want 10 GB for a month, Saily at $17.99 is the better buy. If you want exactly a week, Saily at $26.99 and Holafly at $27.50 both sell one; our 2 weeks at $22.99 costs less than either and lasts twice as long. For 2 weeks or a month of unlimited, Ringo Light is the cheapest of the three.
