The short answer
A regional business loop often runs Singapore, Hong Kong, Tokyo and Seoul, a few days in each. I priced the six regional Asia plans on 25 October 2026 for 3 days, a week, two weeks and a month, and added up Ringo Light's four country plans. For a loop of two weeks across several of these cities I would buy the Ringo Light Asia plan. For three days in one city, I would buy that city's 3-day plan.
One eSIM for Singapore, Hong Kong, Japan and South Korea, 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.
For a short meeting trip across two cities: 3 days of unlimited at $11.50, with 3 GB a day at full speed, then 1 Mbps.
If the laptop stays on hotel wifi and the phone only does maps and email: 10 GB for 30 days at $21 and 20 GB for 45 days at $35 (on sale, regular $40).
A week with 25 GB at full speed for $25, then 2 Mbps. 20 GB a month for $19 if you are fine 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. 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.
Where a business trip across Asia lands, and what your phone needs there
Eight places that a business loop through Singapore, Hong Kong, Japan and South Korea often finds time for, two in each city, with the one thing your data does for you at each. One Asia eSIM works at every one of them.
One plan for the whole trip: Ringo Light
On a business trip the phone has to work when the plane lands, with no time to buy a SIM at an airport kiosk. A regional eSIM is installed before you leave, and it is the same plan in Singapore, Hong Kong, Japan and South Korea. Four country eSIMs mean four installs and four payments to put on one expense line.
On the Asia plan, Ringo Light charges $34.99 for 2 weeks and $59.99 for 30 days, nothing renews. For about two weeks of unlimited on one regional plan, Ubigi asks $45 for 30 GB at full speed, then Airalo $49, Holafly $51.50 and Saily $54.99. For a month the rivals run $66 to $86.99.
Bought city by city on two-week plans, Singapore's $17.99, Hong Kong's $26.99, Japan's $21.99 and South Korea's $23.99 come to $90.96, against $34.99 for the Asia trip that covers all four.
Short trips go the other way. Ringo Light's 3-day country plans cost $8.99 in Singapore and $9.99 in Hong Kong, Japan and South Korea, less than Airalo's regional 3 days at $11.50. Three days in Singapore and three in Hong Kong would be $18.98 on two country plans, still under the $34.99 Asia plan. Ringo Light sells no week on the Asia plan, and for a week I would look at Ubigi at $25 or Airalo at $26, both cheaper. The Asia plan earns its price from two weeks across several cities.
If you hold a longer posting in one city, any of the four country 30-day plans beats the Asia month at $59.99: Singapore $29.99, South Korea $35.99, Hong Kong $45.99 and Japan $54.99.
Which plans cover your stops
Ringo Light covers all four cities on one eSIM. Singapore, Hong Kong, Japan and South Korea are on its list of 20 countries, and so are China and Macau, so a side trip over the border from Hong Kong is on the same plan. What works on a phone in mainland China is a separate question that I did not research here.
For the rivals, I read the country counts in the table (Airalo 18, Holafly 16, Saily 22, Nomad 14, Ubigi 17). The few countries my Asia comparison says they leave out include none of these four. I did not confirm each city's country on every brand's list on the day, so I would open the list for yours before you pay.
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). Enough for email, maps and a ride app.
- 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, which you have to cancel after the trip.
- 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 10 GB, Nomad and Airalo are cheaper, and for 20 GB, Nomad, Airalo and Ubigi's monthly plan are too. I would buy Ringo Light for unlimited, not for a bucket.
What Ringo Light is
I write for Ringo, so weigh what follows. Ringo Light is its data eSIM, 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, Singapore, Hong Kong, Japan and South Korea 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, after the side-by-side table. It is data only, so I would keep your home SIM in for calls and text codes.
Pick by trip
I would buy that city's Ringo Light 3-day plan: $8.99 in Singapore, $9.99 in Hong Kong, Japan or South Korea. Airalo's regional 3 days is $11.50.
I would buy Ubigi's week at $25 or Airalo's unlimited 7 days at $26. Ringo Light sells no week on Asia, and its 2 weeks at $34.99 costs more.
I would buy Ringo Light unlimited, 2 weeks, $34.99, less than any rival charges for two weeks.
I would open that city's page. Every one of the four country 30-day plans costs less than the Asia plan at $59.99.
I would buy Nomad 10 GB for 30 days at $21, if its 14 countries include your cities.
None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
