The short answer
One common Asian cruise route calls at Singapore, a port in Thailand, one in Vietnam and Hong Kong, in some order. I priced the Asia plans that cover those four on 25 October 2026, for the days the ship is docked. I would buy Ringo Light: $34.99 for 2 weeks or $59.99 for 30 days of unlimited data at full speed, one install for every port.
Unlimited data at full speed in 20 countries, Singapore, Thailand, Vietnam and Hong Kong among them, for 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.
Asialink, 18 countries: 3 days of unlimited at $11.50, with 3 GB a day at full speed, then 1 Mbps. The price that fits a short cruise with two or three ports.
APAC plan, 14 countries: 10 GB for 30 days at $21 and 20 GB for 45 days at $35 (on sale, regular $40), plenty for maps and messages on shore days.
Best Asia, 17 countries: 7 days 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
Regional plans, 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, for a long cruise or a cruise plus days on land. 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.

Where a cruise in Asia calls, and what your phone needs at each port
Eight places that often fill the shore days of a cruise through Singapore, Thailand, Vietnam and Hong Kong, with the one thing your data does for you at each. One regional eSIM works in every port the ship docks at.
One plan for every port: Ringo Light
A cruise crosses borders in the night and you wake up in a different country. With country eSIMs you would buy and install one per port and remember to switch lines before you step off the ship. One regional eSIM is installed once at home, and the phone finds a local network in each port when the ship docks.
The regional plan costs far less. Ringo Light's Asia trips are $34.99 for 2 weeks and $59.99 for 30 days, unlimited data at full speed. On the same day I read Airalo at $49 for 15 days and $73.50 for the month, Holafly at $51.50 and $76.50, Saily at $54.99 and $86.99. Ubigi asked $45 for 30 GB over 15 days and $66 for 60 GB over the month, then 2 Mbps.
The sum I worked out from the country pages: Singapore's 2 weeks is $17.99, Thailand's $22.99, Vietnam's $22.99 and Hong Kong's $26.99 on their own, $90.96 together, against $34.99 for the Asia trip that covers all four. A month is $29.99, $32.99, $42.99 and $45.99, $151.96 together, against $59.99. A country plan is the better buy if the cruise has one port that matters: Singapore's 2 weeks at $17.99 is $17 under the Asia plan.
Which plans cover the ports, and what happens at sea
From the Asia page I priced: Ringo Light covers 20 countries, Singapore, Thailand, Vietnam and Hong Kong among them, so every port in this route is in. Airalo's Asialink covers 18, Holafly's Asia plan 16, Saily 22 in its Asia and Oceania plan, Ubigi 17 in Best Asia and Nomad 14 in the APAC plan. I could not confirm on the day whether each of those lists includes all four of these places, so I would look for each port by name at checkout.
Now the part no eSIM can fix. At sea your phone is on the ship's own network or on nothing. An eSIM works in each port when the ship docks, and it works on shore excursions. Once the ship leaves, the plan has no tower to connect to. If the phone joins the ship's satellite network, the ship bills you for that roaming, not the eSIM brand. I would turn data roaming off at sea and use the ship's own Wi-Fi package only if I had to.
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). A bucket suits port days, since the phone is quiet at sea.
- 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, Nomad and Airalo are cheaper, and for 20 GB, Nomad, Airalo and Ubigi's monthly plan are all cheaper. On a cruise with a few port days, a bucket may be all you use. I would rather you read that here than at checkout.
What Ringo Light is
Ringo Light is Ringo's own data eSIM, and I write this guide for Ringo, so weigh that. It is sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For a cruise in Asia it sells two trips across 20 countries, 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

The country plan. Singapore's 2 weeks is $17.99, under the $34.99 Asia plan.
None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
