Cambodia's cheapest verified eSIM rate is $0.98 a gigabyte, and only the 50 GB plan reaches it
Airalo's 50 GB Cambodia plan is $49, which works out at $0.98 a gigabyte. Its 1 GB plan works out at $4.00. Eighteen prices, all read off the checkout on 17 August 2026, from the one provider we hold for Cambodia.
One seller, eighteen prices, one day
We hold plan data for exactly one eSIM provider in Cambodia: Airalo. Eighteen plans, every one of them verified — read off airalo.com on 17 August 2026. That is the whole of our Cambodian coverage, and it is not a survey of the market. Saily, Holafly, Nomad, eSIMCard and eSIM Go all sell travel eSIMs, and we have not priced a single one of them in Cambodia yet, so none of them appears below with a figure beside it. When someone here has read their Cambodian checkouts, the numbers will arrive with a date attached, the way these did.
Airalo lists its Cambodian plans under the name Connect Cambodia. That is Airalo's own retail product label, not an operator. Airalo publishes no host network for Cambodia, and publishes none for any other country either, so we cannot tell you which Cambodian network your phone will attach to. Nor can anyone who has not asked Airalo directly.
The metered ladder
| Data | Days | Price | Per GB |
|---|---|---|---|
| 1 GB | 3 | $4 | $4 |
| 3 GB | 3 | $8.50 | $2.83 |
| 3 GB | 7 | $9 | $3 |
| 5 GB | 7 | $12 | $2.40 |
| 5 GB | 15 | $12.50 | $2.50 |
| 5 GB | 30 | $13 | $2.60 |
| 10 GB | 7 | $19.50 | $1.95 |
| 10 GB | 15 | $20 | $2 |
| 10 GB | 30 | $21 | $2.10 |
| 20 GB | 15 | $30.50 | $1.53 |
| 20 GB | 30 | $32 | $1.60 |
| 50 GB | 30 | $49 | $0.98 |
Twelve metered plans, starting at 1 GB and stopping at 50 GB, with six unlimited plans sold alongside them. The most useful line on that table is the last one. Cambodia has a 50 GB plan, and that is the whole reason its floor sits under a dollar: the rate falls from $4.00 a gigabyte at the bottom of the ladder to $0.98 at the top. A four-fold difference in what a gigabyte costs, decided by nothing but how far down the page you scrolled.
Every rung buys its data more cheaply than the last
The useful question is not which plan holds the lowest rate — that has to be the biggest one — but what stepping up a single size actually costs:
- 5 GB to 10 GB, both over 7 days: $12.00 becomes $19.50. Five more gigabytes for $7.50, or $1.50 each, against the $2.40 each you paid for the first five.
- 10 GB over 7 days to 20 GB over 15: $19.50 becomes $30.50. Ten more gigabytes for $11, and double the window.
- 20 GB over 30 days to 50 GB over 30: $32.00 becomes $49.00. Thirty more gigabytes for $17, which is 57 cents each.
Calendar time is close to free here. The same 5 GB costs $12.00, $12.50 or $13.00 depending on whether you want it for 7, 15 or 30 days — a dollar for twenty-three extra days. At 10 GB it is $19.50, $20.00 and $21.00. If your dates are loose at all, buy the longer window; it is the cheapest insurance on the page.
Unlimited is priced by time, not by data
Six unlimited plans sit beside the metered ones: $12.50 for 3 days, $20.50 for 5, $29.50 for 7, $35 for 10, $49 for 15 and $72.50 for 30.
Two crossing points decide whether any is worth buying. The 3-day unlimited is $12.50 against $8.50 for 3 GB over the same three days — four dollars to stop counting for a weekend, which is fair. At the long end, the 15-day unlimited is $49, exactly what the 50 GB plan costs over 30 days. Unless you genuinely expect to burn through 50 GB in a fortnight, the metered plan hands you twice the calendar for the same money.
Which tier to buy
- A long weekend, maps and messaging. 3 GB over 3 days at $8.50, or 5 GB over 7 days at $12.00 if you would rather not think about it.
- A week, with hotel wifi in the evenings. 10 GB over 7 days at $19.50. The 15-day version is fifty cents more.
- Two or three weeks, or a phone doing some tethering. 20 GB over 15 days at $30.50.
- A month, or two people sharing a hotspot. 50 GB over 30 days at $49.00, the only Cambodian plan we hold that comes in under a dollar a gigabyte.
Thailand is next door and half the price
Cambodia and Thailand get visited on the same trip constantly, and their prices are not close. Airalo's Thai 50 GB plan was $27.50 — $0.55 a gigabyte, the lowest rate anywhere on this site. The Cambodian plan of the same size is $49.00, or $0.98. Same seller, same product size, nearly twice the rate for crossing a land border.
We hold no plan that covers both countries — no regional or multi-country product appears in our data for these markets — so on the evidence we have, a Bangkok-then-Siem-Reap trip means buying twice.
Against its other neighbours Cambodia lands mid-table. The 20 GB / 30-day rung is the one plan size every country in this group sells, and on 17 August Airalo wanted $18 for it in Sri Lanka, $27.50 in Bangladesh, $32.00 in Cambodia, $36 in Nepal and $49 in Laos. Bangladesh is the closer twin: its ladder ends in exactly the same place, 50 GB for $49.00, while sitting a little cheaper at every rung in between. Whatever sets these numbers, it is not a Cambodian cost.
What this page does not tell you
We hold no local SIM data for Cambodia at all: no airport counter prices, no shop advice, no registration rules, no operator names. We have not researched it, so this page stays quiet about it until someone has.
If one of the other five sellers beats $0.98 a gigabyte here, we would not know it — and neither would a page listing all six with figures nobody read. That distinction is how we test. Our Airalo page covers what the company is like to buy from across every country we hold, and the cheapest eSIM plans puts Cambodia's $0.98 next to every other rate on the site.
Common questions
Which eSIM is cheapest in Cambodia?
We can only answer for Airalo, because it is the only provider whose Cambodian prices anyone here has read. Its lowest rate is the 50 GB plan over 30 days at $49, which is $0.98 a gigabyte. Saily, Holafly, Nomad, eSIMCard and eSIM Go are not priced here yet, so we cannot tell you whether one of them undercuts it.
Which Cambodian network does an Airalo eSIM use?
We do not know, and Airalo does not say. It publishes no host network for Cambodia or for any other country. Connect Cambodia, the name on the listing, is Airalo's own product label rather than an operator, so it tells you nothing about coverage either.
Can one eSIM cover both Cambodia and Thailand?
Not in anything we hold. Our data for these markets contains single-country plans only — no regional or multi-country product — so a trip covering both means two purchases on the evidence we have. It is worth knowing that the two countries are priced very differently by the same seller: Airalo's 50 GB plan was $27.50 in Thailand and is $49 in Cambodia.
Is the unlimited plan worth it in Cambodia?
Only on a short trip. The 3-day unlimited at $12.50 is four dollars more than 3 GB over the same three days, which is reasonable for a weekend. The 15-day unlimited is $49, identical to the 50 GB plan that runs for 30 days, so unless you expect to use more than 50 GB in a fortnight the metered plan gives you far more room for the same money.
