The best eSIM for Cambodia in 2026. Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Cambodia, priced on the same day: two weeks unlimited for $31.99, a month for $59.99.
Prices read on 28 September 2026. Six travel eSIMs sell a Cambodia plan and get most of the traffic for this search. We 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, and read the fine print on unlimited. Here is where each one wins.
Ringo Light: Cheapest unlimited for two weeks or a month. Unlimited data at full speed for 2 weeks at $31.99 or 30 days at $59.99, one payment each, nothing renews. Airalo asks $49 for 15 days and $72.50 for the month. Our Asia trip covers Cambodia for less: $26.99 and $47.99.
Ubigi: Cheapest 10 GB bucket, and the biggest month. 10 GB for 30 days at $20, and 60 GB at full speed for 30 days at $68, then 2 Mbps, on Metfone.
Airalo: Cheapest 20 GB and cheapest 3 days. 20 GB for 30 days at $32 and 3 days of unlimited at $12.50, on Smart. Its 15 days at $49 costs less than a heavy two weeks with us.
Holafly: Simplest unlimited. Days, not gigabytes, no daily cap stated for your own phone, on Metfone. $12.50 for 3 days and $27.50 for a week; sharing limited to 1 GB a day.

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, Airalo asks $49 and Holafly $50.50. Saily sells unlimited for Cambodia only on its Asia and Oceania plan, at $54.99 for 15 days. Nomad sells no unlimited here. 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 $31.99 for 2 weeks and $59.99 for 30 days, one payment each, nothing renews.
Read what unlimited means before you pick. 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. Ringo Light has no speed cap: the 2 weeks starts with 10 GB and the 30 days with 20 GB, and when you have used 80% we add 10 GB once and charge the $31.99 top-up. So a heavy two weeks with us costs $63.98, more than Airalo's 15 days at $49 or Holafly's at $50.50. A heavy month costs $91.98, more than Ubigi at $68, Airalo at $72.50 or Holafly at $73.90. If you know you will stream every day, one of those is the better buy in Cambodia.
For a short stay, Ringo Light sells no 3-day or 7-day plan. Airalo and Holafly both sell 3 days of unlimited at $12.50, and Airalo a week at $27.
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 save your bookings and maps offline before the boat.
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. Buckets from $4 for 1 GB.
Saily, $23.99 for 10 GB. No 20 GB plan for Cambodia. Its listing is from July; saily.com would not load for us.
Nomad, $24 for 10 GB. On Metfone, and 20 GB for $36, valid 45 days.
Ringo Light, no buckets. Our 2 weeks starts with 10 GB for $31.99 and our 30 days with 20 GB for $59.99, both unlimited. 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. Buy Ringo Light for unlimited, not for a bucket. We would rather you read that here than at checkout.
Ringo Light is our own data eSIM, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Cambodia it sells two trips, both unlimited data at full speed with no speed cap: 2 weeks at $31.99, starting with 10 GB, and 30 days at $59.99, starting with 20 GB. Each adds 10 GB once at 80%, charged at $31.99. One payment, nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
The card to buy it is just below this article.
One more thing before you buy from us. Our Asia trip covers Cambodia and 18 other countries, Thailand and Vietnam among them, and it is cheaper than our Cambodia trip on both lengths: $26.99 for 2 weeks against $31.99, and $47.99 for 30 days against $59.99, with the same terms. If you buy Ringo Light for Cambodia, buy the Asia trip. The comparison for the region is at /blog/best-esim-for-asia.
Three days at the Angkor temples. Airalo or Holafly unlimited, 3 days, $12.50. Ringo Light sells no 3 days.
Two weeks from Siem Reap to the south coast. Ringo Light unlimited, 2 weeks, $31.99, less than any rival charges for 15 days, or $26.99 on our Asia trip. Airalo 15 days at $49 if you will stream every evening.
Two weeks, light use, budget first. Ubigi 10 GB for 30 days at $20.
A month in Phnom Penh or Kampot. Ringo Light unlimited, 30 days, $59.99, or $47.99 on our Asia trip, starting with 20 GB and adding 10 GB once, charged. Ubigi 60 GB at full speed for $68 if you know you will use a lot.
You need your own number to keep ringing. None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
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.
Angkor Wat, Angkor, near Siem Reap. Built in the early twelfth century for King Suryavarman II, it is the largest religious monument in the world. Come for sunrise, when the towers stand dark against the sky behind the reflecting pools. The Angkor pass is sold online by Angkor Enterprise as well as at the ticket office. Keep it on your phone: it is checked at the temples.
The Bayon, Angkor Thom, near Siem Reap. The state temple of Jayavarman VII at the centre of the walled city of Angkor Thom, its towers carved with more than two hundred calm stone faces. Most people see it on the same day as Angkor Wat, on the small circuit. Grab and PassApp both book tuk-tuks in Siem Reap, with the fare fixed in the app before you set off.
Ta Prohm, Angkor, near Siem Reap. A temple left largely to the forest, with the roots of silk-cotton and strangler fig trees growing over its walls and doorways. Go early in the morning, before the tour groups. The temples are spread over a wide park. Download the area in your maps app so your own position shows between them.
Kampong Phluk, Tonle Sap, south of Siem Reap. A village of houses on tall stilts at the edge of Tonle Sap, the largest freshwater lake in Southeast Asia. The lake swells in the rainy season, and from about August to November the boats float between the houses. Boat trips are paid in cash. Cambodia uses US dollars and riel side by side, and a currency app keeps the change in riel straight.
The Royal Palace and Silver Pagoda, Phnom Penh. The King's residence on the riverfront, with the Throne Hall, the Moonlight Pavilion and the Silver Pagoda, whose floor is laid with silver tiles. Cover shoulders and knees to go in. Parts of the palace close for royal ceremonies. Check the day's opening hours online before you ride over.
The bamboo train, Battambang. A bamboo platform on wheels, driven by a small engine, that now runs on a short line near Phnom Banan, south of town. Pair it with Phnom Sampeau at dusk, when bats stream out of the caves by the million. Battambang is a few hours by bus from Siem Reap or Phnom Penh. Book the seat online and keep the ticket on your phone.
The Kampot riverfront, Kampot. A quiet town of old shophouses on the Praek Tuek Chhu river, with Bokor Mountain across the water. Watch the sun go down from the river, and visit the farms that grow Kampot pepper in the countryside around it. Most people reach the pepper farms and Kep by scooter or tuk-tuk. Download the area offline: the farm roads are easy to lose.
Koh Rong, Off Sihanoukville. An island of white sand beaches and jungle, reached by fast ferry from Sihanoukville. Stay near Koh Toch village for the bars, or on the quieter beaches such as Long Set and Sok San. Book the ferry online and keep the ticket offline: signal is weaker on the far beaches.
We priced Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Cambodia on 28 September 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.

For two weeks or a month of unlimited data, Ringo Light: $31.99 for 2 weeks and $59.99 for 30 days on 28 September 2026, against $49 for 15 days and $72.50 for 30 days at Airalo. Our Asia trip, which covers Cambodia, costs less again: $26.99 and $47.99. For 3 days, Airalo or Holafly at $12.50. For a 10 GB bucket, Ubigi at $20. For 20 GB, Airalo at $32.
Holafly, Nomad and Ubigi ride Metfone, and Airalo rides Smart. Saily does not name its network on its listing. Both cover Phnom Penh, Siem Reap and the main towns; Metfone is often said to reach further into the countryside.
Every brand has a limit somewhere. Airalo slows you after 3 GB a day, Saily's Asia plan after 5 GB, Ubigi after its fixed full-speed amount. Holafly states no daily cap for your own phone. Nomad sells no unlimited plan for Cambodia. Ringo Light has no speed cap: it starts with 10 or 20 GB and adds 10 GB once at 80%, charged.
Yes. Smart, Cellcard and Metfone sell tourist SIMs at the arrival halls in Phnom Penh and Siem Reap, and the SIM is registered with your passport. They cost little per gigabyte, but you queue after the flight and need a free SIM slot. A travel eSIM is installed before you fly and works the moment you land.
