The short answer
Six travel eSIMs sell a Cambodia plan and get most of the traffic for this search. I priced all six on the same day, for three days at the Angkor temples, two weeks from Siem Reap to the south coast and a month in Phnom Penh. I also read the fine print on unlimited. Here is where each one wins.
Unlimited data at full speed for 2 weeks at $37.99 or 30 days at $59.99, nothing renews. Nomad asks $39 for 15 days, Airalo $49, and Airalo $72.50 for the month. Ringo Light's Asia trip covers Cambodia for $34.99 for 2 weeks, $3 less, and $59.99 for 30 days, the same.
10 GB for 30 days at $20, and 60 GB at full speed for 30 days at $68, then 2 Mbps, on Metfone.
20 GB for 30 days at $32, on Smart. Its 3 days of unlimited is $12.50, $1.50 over Nomad.
Days, not gigabytes, no daily cap stated for your own phone, on Metfone. $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.

What to do in Cambodia, and what your phone needs for it
Eight places most first trips include, from the temples of Angkor to Phnom Penh, Battambang and the south coast, with the one thing your data does for you at each. The towns have good 4G; on the lake and on the islands, plan for weaker signal.
If you want unlimited for two weeks or a month: Ringo Light
Most first trips to Cambodia run about two weeks: Siem Reap for the temples, Phnom Penh, then the south coast or the islands. For 15 days of unlimited, Nomad asks $39, Airalo $49 and Holafly $50.50. Saily sells unlimited for Cambodia only on its Asia and Oceania plan, at $54.99 for 15 days. Nomad has no 30-day unlimited. Ubigi sells full speed up to a fixed amount, then 2 Mbps: 30 GB for 15 days at $45 on its Asia plan, 60 GB for 30 days at $68. For a month, Airalo asks $72.50, Holafly $73.90 and Saily $81.99. Ringo Light charges $37.99 for 2 weeks, $1.01 under Nomad, and $59.99 for 30 days, nothing renews, and that is the plan I would buy for either length.
Before you pick, I would read what unlimited means. Airalo gives 3 GB a day at full speed, then 1 Mbps. Saily's Asia plan gives 5 GB a day, then slows you down. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Nomad's page states no daily allowance for its unlimited. Ringo Light is unlimited data at full speed for the whole 7 days, 2 weeks or 30 days.
For a short stay, Ringo Light sells no 3-day plan, but its 7 days at $8.99 costs less than Nomad's 3 days at $11, Airalo's at $12.50 and Holafly's at $13.50, and far less than a week at $25 at Nomad, $27 at Airalo or $27.90 at Holafly.
Which network works best in Cambodia
Cambodia has three main networks: Metfone, Smart and Cellcard. All three cover Phnom Penh, Siem Reap and the main towns on 4G. Metfone, owned by Vietnam's Viettel, is the one most often said to reach furthest into the countryside, and three of the five rivals here ride it: Holafly, Nomad and Ubigi. Airalo rides Smart, and Saily does not say. Signal thins out on Tonle Sap, in the hills and on the islands off Sihanoukville, whichever network you use, so I would save your bookings and maps offline before the boat.
If you want a data bucket: Ubigi or Airalo
- Ubigi, $20 for 10 GB. The cheapest 10 GB for 30 days, on Metfone, and 25 GB for $39.
- Airalo, $21 for 10 GB. And the cheapest 20 GB at $32, both for 30 days on its Connect Cambodia plan, on Smart.
- Saily, $23.99 for 10 GB. No 20 GB plan for Cambodia. Its listing is from 5 October; saily.com refused the fetch.
- Nomad, $24 for 10 GB. On Metfone, and 20 GB for $36, valid 45 days.
- ✓Ringo Light, no buckets. Ringo Light's 2 weeks is unlimited for $37.99 and its 30 days unlimited for $59.99. For a fixed amount of data, all four bucket sellers are cheaper in Cambodia: 10 GB for $20 at Ubigi, 20 GB for $32 at Airalo. I would buy Ringo Light for unlimited, not for a bucket, and I would rather you read that here than at checkout.
What Ringo Light is
I write for Ringo, so here is what Ringo Light is: a data eSIM, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Cambodia it sells three trips, all unlimited data at full speed with no speed cap: 7 days at $8.99, 2 weeks at $37.99 and 30 days at $59.99. 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.
One more thing before you buy Ringo Light. Its Asia trip covers Cambodia and 18 other countries, Thailand and Vietnam among them, and it is $3 cheaper than the Cambodia trip for 2 weeks, $34.99 against $37.99, and the same for 30 days at $59.99, with the same terms. If you buy Ringo Light for Cambodia, I would buy the Asia trip. The comparison for the region is at /blog/best-esim-for-asia.
Pick by trip
Nomad unlimited, 3 days, $11, or Airalo at $12.50. Ringo Light sells no 3 days.
Ringo Light unlimited, 2 weeks, $37.99, less than any rival charges for 15 days, or $34.99 on Ringo Light's Asia trip. That is my pick.
Ubigi 10 GB for 30 days at $20.
Ringo Light unlimited, 30 days, $59.99, the same on the Asia trip, which covers 18 other countries too.
None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
Frequently asked questions
How we compared, and our sources
Airalo, Holafly, Saily, Nomad, Ubigi, Ringo Light
We priced Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Cambodia on 11 November 2026, all on the same day, in US dollars. Each rival's price comes from its own website where it showed dollars, otherwise from an esimdb.com listing, and every source and its date is listed below. Ringo Light's prices come from the catalogue our checkout charges.
We compare the trips people actually book: a week, two weeks and a month of unlimited data, and a 10 GB bucket. We read each brand's fair use and speed rules and quote them as the brands state them. We did not run speed tests, so this page makes no speed claims for any brand.
Ringo Light is our own product. We put it in the table on the same terms as everyone else, and where a rival is the better buy the page says so.
Left out: Maya Mobile. We could not read its own prices for this country on the day, so it stays out rather than being guessed.
