Macau's verified eSIM floor is $0.98 a gigabyte, and it is the one plan here most visitors should skip
Airalo's 50 GB Macau plan is $49, or $0.98 a gigabyte. Its 20 GB plan is $22.50, or $1.13 — close enough that the big plan rarely earns its money. Eighteen prices, read off the checkout on 17 August 2026.
One seller, eighteen prices, one date
We hold plan data for exactly one eSIM provider in Macau: Airalo. Eighteen plans, all verified, read off airalo.com on 17 August 2026. That is the whole of our Macau coverage, and it is not a market survey. Saily, Holafly, Nomad, eSIMCard and eSIM Go all sell travel eSIMs; none of them has been priced here yet, so none appears below with a figure beside it.
A note on the name before the numbers: Airalo files this market as Macao and calls the product Macao Mobile, while this page uses Macau throughout. Both spellings are correct and both refer to the same place, so search for whichever you prefer. Macao Mobile is Airalo's own retail label rather than a carrier — Airalo publishes no host network for Macau, or for any other country, so we cannot tell you which operator the eSIM attaches to.

Twelve metered plans, from 1 GB to 50 GB, with nothing above.
The rung that does not fit
Almost every country page on this site ends up saying the same thing: buy the biggest plan, because the rate falls all the way down and the largest tier is the only decent value. Macau is the exception, and it is worth being precise about why.
The first eleven rungs fall gently. By 10 GB the rate is $1.50 a gigabyte and by 20 GB it is $1.13 — already within fifteen cents of the floor. Then the ladder jumps: 20 GB over 30 days is $23, and 50 GB over 30 days is $49. More than double the money for thirty extra gigabytes, which works out at 87 cents each. Cheaper than everything below it, yes, but only just, and you have to actually use those thirty gigabytes for the saving to be real.
Unused data is worth nothing. A visitor who burns 12 GB pays $23 and lands at $1.92 a gigabyte on the 20 GB plan, or $49 and $4.08 a gigabyte on the 50 GB one. On a short trip, the 20 GB plan is very often the right answer here.
A price set in an office, not in Macau
The reason that top rung sits so awkwardly is that it is not really a Macau price. Airalo charges $49 for 50 GB over 30 days in 18 of the 56 countries where we hold a 50 GB figure at all, from Iceland to Bangladesh to Colombia. It is a policy number applied across the map.
Four other markets were priced the same afternoon — China, Hong Kong, Mongolia and Kazakhstan — and every one of them carries that same $49 plan, and the same $4 plan at 1 GB. Between those two pinned rungs they diverge, and Macau comes out cheapest of the five nearly all the way up. Airalo's 20 GB over 15 days is $22.50 in Macau against $28 in Hong Kong and $39 in China. Its 10 GB over 7 days is $15 here and $24.50 in China.
So Macau gets a genuinely low mid-ladder and then inherits a floor set somewhere else. For reference, $0.98 is mid-table across this site — Thailand's verified floor is $0.55 a gigabyte and Austria's $0.58, while Kenya sits at $4.60 and Fiji at $4.70 among the 94 countries covered.
Unlimited, priced by the day
Six unlimited plans: $11.50 for 3 days, $19.50 for 5, $27 for 7, $35 for 10, $49 for 15 and $72.50 for 30.
The comparisons are unkind. The 15-day unlimited is $49, the same as 50 GB running twice as long. The 3-day unlimited at $11.50 costs more than 5 GB over 30 days at $10, and $4.50 more than 3 GB over the same 3 days. Given how cheap the small metered plans are in Macau, unlimited only makes sense if you are tethering hard and want the counter to stop mattering.
Which plan for which trip
- A night or two. 3 GB over 3 days at $6.50. The cheapest sensible plan we hold here.
- A few days, with maps and messaging. 5 GB over 7 days at $9.
- A week of real use. 10 GB over 7 days at $15, or $15.50 for the 15-day version if your dates are loose.
- Two weeks, or a phone feeding a laptop. 20 GB over 15 days at $22.50 — the sweet spot on this ladder.
- A month of heavy use. 50 GB over 30 days at $49 — the only option above 20 GB, since the ladder holds nothing in between.
What this page does not cover
We hold no local SIM data for Macau: no counter prices, no shop advice, no registration rules, no operator names. Nobody here has researched it, so this page stays quiet on it.
We also cannot tell you what these plans cover outside Macau. Airalo prices Macau, Hong Kong and mainland China as three separate listings, which shows they are sold separately but not what each includes at the edges — check the coverage note on the listing rather than assuming.
And we hold nothing for the other five sellers. If one of them beats $0.98 a gigabyte here, we would not know it, and neither would a page that lists all six with figures nobody read. That distinction is the whole of how we test. Our Airalo page covers the company across every country we hold, and the cheapest eSIM plans puts this $0.98 beside every other rate on the site.
Common questions
Which eSIM is cheapest in Macau?
By rate, Airalo's 50 GB plan over 30 days at $49 — $0.98 a gigabyte. By outlay for a normal trip, the 20 GB plan over 15 days at $22.50 is usually the better buy at $1.13 a gigabyte. Airalo is the only provider whose Macau prices anyone here has read, so we cannot say whether Saily, Holafly, Nomad, eSIMCard or eSIM Go undercuts it.
Is it Macau or Macao?
Both. The two spellings are in standard use for the same territory, Macau following the Portuguese form and Macao the common English one. Airalo files the market as Macao and names the product Macao Mobile; this page uses Macau throughout. Whichever you search for, the prices are the same eighteen plans.
Which Macau network does an Airalo eSIM use?
We do not know, and Airalo does not publish it — not for Macau and not for any other country. Macao Mobile is Airalo's own product name rather than an operator, so it tells you nothing about coverage. Anyone stating a host network for an Airalo plan is guessing.
Should I buy the 50 GB plan in Macau?
Only if you expect to pass 20 GB, because nothing sits between the two tiers. It costs $49 against $23 for 20 GB over the same 30 days, so the extra thirty gigabytes cost 87 cents each — cheap per gigabyte, but worth nothing unused. Stay under 20 GB and the smaller plan saves you $26.
