The short answer
Six travel eSIMs sell a Hong Kong plan and get most of the traffic for this search. I checked all six on the same day, for a stopover of a few days, a week in the city, two weeks with day trips to Lantau and the New Territories, and a month, and read the unlimited terms line by line. These are the plans I would put my own money on.
Unlimited data at full speed for 2 weeks at $26.99 or 30 days at $45.99, nothing renews. Airalo asks $49 for 15 days and $71 for the month.
10 GB for 30 days at $14 and 25 GB at $26 on SmarTone, and 20 GB at full speed for 7 days at $23, then 2 Mbps.
3 days of unlimited at $12.50 on HKT, with 3 GB a day at full speed, then 1 Mbps.
Days, not gigabytes. $13.50 for 3 days and $27.90 for a week; sharing limited to 1 GB a day.
Prices read on 11 November 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
US dollars, 11 November 2026. The rivals sell 15 days, Ringo Light 2 weeks. Ubigi's 15 days is 30 GB at full speed, then 2 Mbps. Nomad sells no unlimited past 10 days.
The 30-day plan at each brand. Ubigi's month is 60 GB at full speed, then 2 Mbps. Nomad stops at 10 days.
Holafly sells no buckets. Ringo Light sells no bucket either: its 2 weeks is unlimited and 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.
What to do in Hong Kong, and what your phone needs for it
Eight places most first trips include, from Victoria Peak to Tai O on Lantau, with the one thing your data does for you at each. Hong Kong is compact: all eight are on the MTR, a ferry or a bus from it, and 4G and 5G cover almost every one.
If you want unlimited for two weeks or a month: Ringo Light
Many people see Hong Kong on a stopover, but plenty stay a week or two, and some come for a month of work. I compared 15 days of unlimited first: Saily asks $48.99, Airalo $49 and Holafly $50.50. For a month, $71, $71.99 and $73.90. Ubigi asks $39 and $55 for a fixed amount at full speed, and Nomad sells no unlimited past 10 days. Ringo Light charges $26.99 for 2 weeks and $45.99 for 30 days, nothing renews.
Before any price, I look at what the word unlimited buys you. Airalo gives 3 GB a day at full speed, then 1 Mbps. Saily gives 5 GB a day, Nomad 2 GB. Ubigi gives 30 GB for 15 days or 60 GB for the month, then 2 Mbps. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Ringo Light is unlimited data at full speed, for 2 weeks or 30 days.
On a short stopover I would pay for Ringo Light, which sells 3 days of unlimited data at $9.99 and has no 7-day plan. Airalo sells 3 days of unlimited at $12.50 and Holafly at $13.50. For a week, Ubigi's 20 GB at full speed is $23, Airalo asks $26.50 and Holafly $27.90; the 2 weeks of Ringo Light at $26.99 costs about the same as their week and lasts twice as long, which is why I lean that way.
Which network works best in Hong Kong, and the border with China
Hong Kong has four mobile networks: csl, run by HKT, SmarTone, 3 Hong Kong and China Mobile Hong Kong. The city is dense and all four cover the streets, the MTR underground, the Star Ferry and the airport well. Signal thins out on the country park trails and the far side of Lantau. Airalo rides HKT, Nomad China Mobile Hong Kong and csl, and Ubigi SmarTone. Holafly and Saily do not name a network. For a city trip any of them works.
Inside Hong Kong, Google, WhatsApp and Instagram work as they do at home. No Hong Kong plan, Ringo Light included, goes past the border with Shenzhen and none covers Macau across the water. If your trip continues into mainland China or Macau, I would look at a regional plan: Nomad sells a Greater China plan, and Airalo, Saily and Ubigi sell Asia plans that cover more than one place.
If you want a data bucket: Ubigi or Nomad
- Ubigi, $14 for 10 GB. The cheapest 10 GB for 30 days, on SmarTone. Its 20 GB is $18 a month, but that plan renews; the one-off 25 GB for 30 days is $26.
- Nomad, $16 for 10 GB. On China Mobile Hong Kong and csl. It sells no 20 GB for 30 days; 20 GB for 45 days is $27.
- Airalo, $18 for 10 GB. Its Hkmobile plan on HKT, 20 GB for $29.
- Saily, $19.99 for 10 GB. 20 GB at $36.99. Its listing is dated 4 October; saily.com refused the fetch.
- ✓Ringo Light, no buckets. Its 2 weeks is unlimited for $26.99 and its 30 days unlimited for $45.99. For 10 GB that lasts a month, Ubigi, Nomad, Airalo and Saily are all cheaper, and for 20 GB Ubigi, Nomad, Airalo and Saily all cost less than the 30 days of Ringo Light. Buy Ringo Light for unlimited, not for a bucket.
What Ringo Light is
I should say where I stand: Ringo Light is the data eSIM of the company I write for, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Hong Kong it sells three trips, all unlimited data at full speed: 3 days at $9.99, 2 weeks at $26.99 and 30 days at $45.99. 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
Ringo Light unlimited, 3 days, $9.99, against $12.50 at Airalo and $13.50 at Holafly; its 2 weeks is $26.99 if you might stay longer.
Ringo Light unlimited, 2 weeks, $26.99, twice the days of Airalo's week at $26.50.
Ubigi 10 GB for 30 days at $14, or Nomad at $16.
Ringo Light unlimited, 30 days, $45.99. Ubigi at $55 for 60 GB at full speed if you move big files every day.
A regional plan: Nomad's Greater China, or an Asia plan from Airalo, Saily or Ubigi. Hong Kong plans, Ringo Light included, stop at the border.
None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
