The short answer
Tokyo and Kyoto first, then a flight south to Hong Kong for the harbour and the night markets, is a route many people book together. I priced the six regional plans on 25 October 2026 for a week, two weeks and a month, and added up what Ringo Light charges for Japan and Hong Kong as two separate country plans. For two weeks or a month across both, my pick is the Ringo Light Asia plan.
One eSIM covering both places, unlimited data at full speed: 2 weeks at $34.99 or 30 days at $59.99, and nothing renews. Airalo charges $49 for 15 days and $73.50 for a month.
For a long weekend that ends in Hong Kong: 3 days of unlimited at $11.50, with 3 GB a day at full speed and then 1 Mbps.
If maps and messaging are all you use: 10 GB for 30 days at $21, or 20 GB for 45 days at $35 (on sale, regular $40).
A week with 25 GB at full speed costs $25, then 2 Mbps. A monthly 20 GB plan costs $19 and renews until you cancel it.
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 work in both places, 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 none either: its 2 weeks is unlimited, so it lasts 2 weeks, not 30 days.

We sell data eSIMs for now to fund the full Ringo service. Ringo is self funded. Every plan bought here pays for the build of one plan that works everywhere.
Want to keep your own number abroad?
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 Japan and Hong Kong, and what your phone needs for it
Eight stops that many trips through Japan and Hong Kong include, four in each place, with the one thing your data does at each. One Asia eSIM stays on at all of them.
One plan for both places: Ringo Light
Japan and Hong Kong are a flight apart, and a regional eSIM means the plan you installed at home is already running when you land. Two country eSIMs mean two installs, two payments and a settings change in the departure hall. I would rather arrive with one.
On the Asia plan I read Ringo Light at $34.99 for 2 weeks and $59.99 for 30 days, and nothing renews. For two weeks of unlimited on a regional plan the others run $45 at Ubigi (a fixed 30 GB at full speed), $49 at Airalo, $51.50 at Holafly and $54.99 at Saily. For a month they run $66 to $86.99.
Buying Ringo Light's two country plans costs more than the one regional plan. Japan's 2 weeks is $21.99 and Hong Kong's is $26.99 on their own pages, $48.98 together, against $34.99 for the Asia trip that covers both. For a month, Japan's 30 days is $54.99 and Hong Kong's $45.99, $100.98 together, against $59.99 for Asia.
There is one case where I would not buy the Asia plan. If you spend the whole fortnight in one place, Hong Kong alone at $26.99 or Japan alone at $21.99 is cheaper than $34.99. The regional plan earns its price when you really cross over.
Which plans cover both countries
Ringo Light covers both. Japan and Hong Kong are on its list of 20 countries, so the same eSIM works in each at the same price.
For the rivals I have the country counts from the table (Airalo 18, Holafly 16, Saily 22, Nomad 14, Ubigi 17) and the few countries the parent post names as left out, and neither Japan nor Hong Kong is among them. I could not confirm both places one by one on every brand's list on the day, so I would open the list for your brand before paying.
If you want a data bucket: Nomad or Airalo
- Nomad, $21 for 10 GB. The lowest price for 10 GB, on a 14-country APAC plan. Its 20 GB for 45 days is $35 while on sale, $40 at the regular price.
- Airalo, $25 for 10 GB. Asialink covers 18 countries. 20 GB for 30 days is $39, and small buckets start at $4 for 1 GB.
- Ubigi, $28 for 10 GB. Best Asia covers 17 countries. The $19 for 20 GB is a monthly plan that renews until you stop it.
- Saily, $35.99 for 10 GB. Asia and Oceania, 22 countries. I found no 20 GB bucket on its listing, read on saily.com on 25 October 2026.
- ✓Ringo Light, no buckets. Its 2 weeks is $34.99 and its 30 days $59.99, both unlimited. For 10 GB, Nomad and Airalo cost less, and for 20 GB so do Nomad, Airalo and Ubigi's monthly plan. I would buy Ringo Light for unlimited and not for a bucket.
What Ringo Light is
Ringo Light is Ringo's own data eSIM, and I write for Ringo, so weigh my view with that in mind. It is sold to pay for the full Ringo, a single plan that works everywhere with your own number ported onto it. For Asia it sells two trips across 20 countries that include Japan and Hong Kong, both unlimited data at full speed: 2 weeks at $34.99 and 30 days at $59.99. Nothing renews. The eSIM arrives by email within seconds and installs with one scan, no app needed.
The card to buy it sits further up this page, just after the side-by-side table.
Pick by trip
I would open the Japan page. Ringo Light sells no week, but its Japan 2 weeks at $21.99 costs less than the Asia plan.
I would buy Ubigi's week with 25 GB at $25, or Airalo's 3 days at $11.50 if the trip is short. Ringo Light has no 3 or 7 day plan on Asia.
My pick is Ringo Light unlimited for 2 weeks at $34.99, the lowest regional price for that length.
I would buy Ringo Light unlimited for 30 days at $59.99.
I would buy Nomad's 10 GB at $21 after checking that its 14 countries include both of yours.
None of these travel plans does that. The full Ringo, which Ringo Light helps fund, ports the number you already have.
