What it costs per day
Cheapest per day: 3 GB for 30 days at 28¢ a day. The dearest per day is Unlimited for 3 days at $4.16. Short plans always cost more per day: validity is rounded up, and unused days are paid for anyway.
How much data to buy
Four ways people use a phone abroad, sized against this country’s own plans. The gigabytes are an estimate built from published per-hour rates — nobody measured your phone.
The hours behind each row are our assumption, not yours — put your own in and the same rates do the arithmetic.
Where a row shows a range, the cell is sized on the lower number, which assumes the evening runs on hotel Wi-Fi. On mobile data around the clock, read the upper number and take the next size up. The per-hour rates and the 15% added for background traffic are listed with their sources in the calculator.

Does this apply to you? (the regulator answers this one directly)
Hong Kong’s SIM registration rule does not cover a roaming eSIM. The regulator excludes it by name, in writing. Section 2.5(b) of GN 15/2021 states it directly. The Office of the Communications Authority issued that guidance, checked 15 August 2026.
That’s the case for Hkmobile, Airalo’s eSIM for Hong Kong. It’s sold for use on arrival, data-only, with no Hong Kong phone number attached. Buying and installing it before you land creates no Hong Kong number. It triggers no registration duty.
The rule instead binds Hong Kong’s own licensees. These are the operators that sell a local number under contract. GN 15/2021 states their duty this way: a licensee must not activate a SIM card for use in Hong Kong unless that card is registered with it. The identity check sits inside that registration step — the same guidance lists a Hong Kong identity card, or a travel document including a passport, as what an individual hands over. That duty has stood since 1 September 2021 (Office of the Communications Authority, GN 15/2021, checked 15 August 2026). Sign up for a Hong Kong number directly with a Hong Kong carrier, and the duty reaches you in full. A physical prepaid SIM at a convenience-store counter is the common example — ID or passport required.
A roaming eSIM sits outside that transaction. Your contract is with Airalo and Hkmobile’s issuing partner. It is not with a Hong Kong licensee selling you a Hong Kong number. GN 15/2021 answers an objection before you can raise it. Doesn’t the profile still run on a Hong Kong network? Section 2.5(b) settles that in the same clause. The exclusion holds “although the network involved is provided by a licensee”. Which network carries your data doesn’t decide whether the registration duty applies. Whose contract issued the SIM does.
The next section quotes the guideline in full. It shows exactly where the Communications Authority draws that line.
What the Regulation says, and what the guidelines exclude
GN 15/2021 is the Communications Authority’s guidance on implementing Cap. 106AI. Section 2.5 draws the registration boundary directly, as a numbered list of exclusions.
The underlying duty comes first, in paragraph 12:
The Telecommunications (Registration of SIM Cards) Regulation (Cap. 106AI)... which came into operation on 1 September 2021, imposes a general obligation on licensees supplying telecommunications services through SIM cards in Hong Kong to ensure that the SIM cards provided or offered by them are not activated for use in Hong Kong unless the SIM cards are currently registered with them.
Section 2.5 then lists what that duty does not reach. Subsection (b) covers this exact case:
SIM cards provided by service providers licensed elsewhere (i.e. non-licensees) for use in Hong Kong (although the network involved is provided by a licensee), including for example (i) SIM cards provided by service providers licensed elsewhere and used by visitors in Hong Kong by means of inbound roaming to the local mobile networks
A footnote attached to that subsection states the consequence directly. A SIM card meeting that description “falls outside the scope of the Regulation”. That holds even if the card carries a Hong Kong number, the footnote adds. Nothing here needs interpreting from a definition. The Communications Authority names inbound roaming as an exclusion, in the same document that sets the registration duty.
A second clause in the guidance backs the same reading. Footnote 8 defines a regulated SIM card as one “provided by a specified licensee”. That card must identify a subscriber’s access to “a telecommunications service provided in Hong Kong by any specified licensee”. Hkmobile is sold as the other thing: Airalo’s catalog lists it as a data-only roaming profile riding HKT, with no Hong Kong number and no Hong Kong subscription attached (Airalo catalog data, checked 15 August 2026). Both routes through the guidance land on the same answer: this eSIM for Hong Kong sits outside the rule.
One load-bearing piece of that is worth naming rather than glossing. The exclusion turns on the SIM being provided by a non-licensee, so the argument rests on Hkmobile being issued outside Hong Kong. Our evidence for that is the product’s own catalog description — roaming, no local number, no local subscription — not a licence register we have opened and checked. If you need certainty at that level rather than a strong reading, ask Airalo support to confirm the issuing operator in writing before you travel.
One honest limit on this section: we have not read the text of Cap. 106AI itself. Hong Kong’s e-legislation site returns an empty application shell, even with scripts executed. No PDF of the ordinance sits at the addresses we checked. Both quotes above come from GN 15/2021, the Communications Authority’s own guidance document. That document cites the Regulation’s operative text and definitions. That’s a primary source from the regulator. It is not the ordinance’s own text, and the difference is worth stating plainly rather than blurring.
The «three SIM cards» figure is wrong — the document says ten
The limit in GN 15/2021 is ten SIM cards per individual user, not three.
A three-card cap for Hong Kong circulates in secondary write-ups. We hold no Hong Kong search capture, so we can’t say how widely it travels — only what the guidance itself says. Section 2.6 states the actual figure. A licensee “shall register no more than 10 SIM cards for any individual user,” and 25 for an organisation user. That’s Office of the Communications Authority guidance, GN 15/2021, checked 15 August 2026. Ten, on a licensee, per user. Not three.
That cap sits on a Hong Kong licensee registering SIM cards under its own name. It’s the same population covered by the registration duty above. It has no bearing on a roaming eSIM bought from Airalo. That eSIM never becomes a Hong Kong licensee’s registered SIM to begin with. The correction stands regardless of that scope. If you read “3 SIM cards” anywhere else about Hong Kong, that figure doesn’t match the document that sets the rule.
What you get: Hkmobile on HKT, 5G, data-only
Hkmobile is Airalo’s eSIM for Hong Kong, roaming on the HKT (Hong Kong Telecommunications) network at 5G, data-only. It carries no Hong Kong phone number and no voice line. That description — a foreign-issued SIM roaming in, rather than a Hong Kong subscription — is what section 2.5(b) names as excluded. The exclusion follows from who issued the SIM, not from how much data the plan holds (Airalo catalog data, checked 15 August 2026).
| Data | Duration | Price |
|---|---|---|
| 1 GB | 7 days | $3.99 |
| 2 GB | 15 days | $6.49 |
| 3 GB | 30 days | $8.49 |
| 5 GB | 30 days | $10.99 |
| 10 GB | 30 days | $15.99 |
| 20 GB | 30 days | $23.99 |
Airalo lists its own rate separately on its site.
The plan installs within a 365-day window from purchase. That’s the install deadline, not a usage clock. The data validity period starts only once your phone makes its first connection to HKT after landing. Not at installation, and not at checkout (Airalo catalog data, checked 15 August 2026). Checkout carries no KYC step and no ID upload. Hkmobile’s roaming design keeps it outside the registration duty covered above. It never becomes a Hong Kong licensee’s own registered line. That’s not an exemption from a duty it would otherwise carry. The duty never attaches in the first place.
The APN Android makes you type: wbdata
On Android, type wbdata into the APN field manually. Without it, Hkmobile installs but carries no data. iOS sets the APN automatically once the profile installs; Android doesn’t (Airalo catalog data, checked 15 August 2026).
The setting sits under Settings > Network & internet > SIMs > Hkmobile > Access Point Names on stock Android. The exact menu path shifts slightly by phone maker. Add a new APN. Set the APN field to wbdata. Leave the other fields at their defaults. Save, then select it as the active APN for the Hkmobile line.
Android’s manual-entry requirement covers 73 of the catalog’s 215 countries — Hong Kong among them, 121 of 368 operator entries overall (checked 3 September 2026). Worth ruling out first if the eSIM shows installed but carries no data. Do this once, on Wi-Fi, before you rely on the connection. It takes under a minute.
Before you fly, and on landing
Install the profile before you leave, on a working Wi-Fi connection. Not at the airport. The QR code or install link needs internet to complete. An airport connection on landing isn’t guaranteed. The install window runs 365 days from purchase, so buying weeks or months ahead costs nothing (Airalo catalog data, checked 15 August 2026).
Nothing activates at install. Hkmobile starts its own data clock at first connection to HKT — not at checkout, and not at install. A profile that shows installed but inactive before you board is expected. It’s not a fault.
On landing, switch on data roaming for the Hkmobile line specifically. Confirm the APN field reads wbdata, if you haven’t set it already. Running Hkmobile alongside a home SIM works on any dual-SIM phone. Set Hkmobile as your data line. Turn off cellular data — not the whole line — on your home SIM. That way nothing pulls an expensive home-carrier roaming connection by accident.
On general reliability, one dated community report covers Hong Kong directly: "I’m still a customer with 6 esims on the go. No issues in the last month across: China, HKG, Japan, EU, UK and Canada" (u/Puslinch-Komet, r/Airalo, 4 July 2024). That’s a report about the connection completing. It is not a statement about registration status — the question this page has already answered above.
A Hkmobile profile carries no Hong Kong phone number, no SMS, and no calling minutes. Anything that verifies you by SMS to a Hong Kong number sits outside what a data-only profile does. Think a delivery app, a local bank’s one-time code, or a loyalty sign-up. Set those up before you fly, on your home number, if you’ll need them.

Sources and freshness
Checked against two documents published by Hong Kong’s Office of the Communications Authority. GN 15/2021 is titled “Guidelines on Implementation of Real-name Registration for SIM Cards” (August 2021). GN 11/2024 is titled “Guidelines for Administration of the Class Licence for Offering Services to Third Parties for the Purpose of Constructing, Maintaining and/or Operating any Telecommunications Network”. Both were read via Scrapfly (country=hk) on 15 August 2026, against Hkmobile’s Airalo catalog data checked the same date. We have not read the text of Cap. 106AI itself. Hong Kong’s e-legislation site returns an empty application shell, even with scripts executed. No PDF of the ordinance sits at the addresses we checked. Both guidance notes quote the Regulation’s operative text and its definitions directly. Every legal claim on this page traces to one of those two documents — not to the ordinance’s own text. GN 15/2021 and GN 11/2024 can be amended or superseded, and this page won’t update automatically.
