“It seems the roaming provider has changed from Singtel to KPN. As a result, data now routes through the Netherlands, thus higher latency than before (200+ms). It connects to Smart network. There were several occasions when the signal dropped to "E" (Edge), and data could not be used. This might be due to local coverage issues. The latency is still manageable, but the occasional loss of connectivity is a bit inconvenient. I wouldn't recommend it.”

“The speeds are decent, but the IP is from Hong Kong so the latency is quite high. And most importantly, ChatGPT cannot be used unfortunately.”

Airalo Cambodia

“It works flawlessly! The speed was above 80mbps (download) most of the time which I did not expect for a prepaid eSIM, way better than my expectation. Roaming via Singapore with latency around 100ms.

It connected to Smart network and the coverage was good in Phnom Penh. No issues whatsoever.

Highly recommend this.”

Cambodia Travel eSIM FAQ

Everything you need to know about using eSIMs in Cambodia

How many travel eSIM brands (providers) are available for use in Cambodia, and how many prepaid data plans are there?

There are more than 210 travel eSIM brands available in Cambodia, and there are over 10, 600 prepaid data plans. With such a wide variety of options, travelers can easily find an eSIM that suits their needs.

Are there any unlimited data eSIM plans available for Cambodia?

Several eSIM providers offer unlimited‑data plans for travel to Cambodia. These options are available in validity periods ranging from one to thirty days, with prices typically falling between roughly $3.30 and $72.00 USD. Each unlimited plan allows tethering, but most come with a speed limitation—commonly a 5 Mbps cap or equivalent throttling that may reduce throughput after a certain threshold. For example, ASIMGO, Earth Esim, Roamify, MicroEsim, Yesim, and Orange Travel each provide unlimited data, and prices vary across the range mentioned. Travelers should still estimate their data needs based on the intended use—such as streaming, social media, navigation, and downloads—and choose a plan that offers sufficient bandwidth and time to match those activities.

What are the major mobile networks available for a travel eSIM in Cambodia?

Cambodia's mobile telecommunications sector is served by several major Mobile Network Operators (MNOs), each offering a range of services and coverage:

Smart Axiata: A subsidiary of Malaysia's Axiata Group Berhad, Smart Axiata provides extensive 2G, 3G, 4G LTE, and 5G-ready services, including voice, SMS, and data, with a significant market share in Cambodia.
Cellcard (CamGSM): As Cambodia's longest-serving and only 100% Cambodian-owned operator, Cellcard offers nationwide coverage with 2G, 3G, and 4G services, catering to over four million customers.
Metfone: Owned by Vietnam's Viettel Group, Metfone provides 2G, 3G, and 4G LTE services, including voice, SMS, and data, with extensive coverage, especially in rural areas.
Seatel (South East Asia Telecom Cambodia Co. Ltd): A Cambodian-owned operator offering 4G LTE services, including voice, SMS, and data, with a focus on providing high-quality digital services nationwide.
CooTel (Xinwei Telecom Enterprise Group): A Chinese-owned operator that introduced 4G technologies to Cambodia, offering voice, SMS, and data services with a focus on high-speed internet connectivity.

In Cambodia, Mobile Virtual Network Operators (MVNOs) are not prevalent. Most travel eSIMs rely on the infrastructure of the major MNOs listed above to provide services.

Can I get a travel eSIM with a phone number and SMS for Cambodia?

Travel eSIM plans that include a phone number and SMS for Cambodia are available. RedEx eSIM offers a local Cambodia number with dialing code +855, 20GB of data, 15 calls, 50 SMS, a 30‑day validity, and a price of $35.89. Other providers such as GlobaleSIM, Roamify, Airhub, Simbye, LineCast Networks, eSIMX, Orange Travel, and FlyEsim.me also supply eSIMs that provide a phone number and SMS, but the numbers use foreign dialing codes such as +1 or +33, so they are not local Cambodia numbers. Prices for these plans start around $4 for 1GB data and can rise to $105 for 20GB data with 200 calls and 200 SMS over 365 days. Travelers should verify that the chosen plan’s dialing code matches their needs and that local services are accessible in Cambodia before purchasing.
