See what travelers are saying about their Cambodia eSIM experience. Real feedback from real users to help you pick the best plan for your trip.

“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.”

“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.”
Everything you need to know about using eSIMs in Cambodia
There are more than 250 travel eSIM providers and over 15, 400 prepaid data plans available for Cambodia, giving travelers a wide variety of options to choose from.
Yes, several eSIM providers offer unlimited data plans that are valid for use in Cambodia. Those providers include ESIM.DOG, ASIMGO, Earth Esim, Yesim, Roamify, MicroEsim, and Orange Travel. All of the listed plans are available for periods between one and fifteen days, use 5G networks, and allow tethering. Speed throttling may apply on some plans; for example, ESIM.DOG offers speeds that can be limited to 128 kbps, 384 kbps, or 1 Mbps, ASIMGO and Earth Esim allow up to 5 Mbps, and Earth Esim also offers a 1 Mbps limit on some options. Prices for these unlimited data plans generally fall between roughly $2 and $30 USD, depending on the provider and the length of validity.
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.
Travel eSIM providers for Cambodia do offer plans that include a phone number and SMS capabilities. The cheapest plans start at about $4 USD and the most expensive can reach approximately $105 USD for a 20 GB data allowance over 365 days. Seven‑day to 365‑day validity periods are available, and the options are offered by multiple carriers: GlobaleSIM, Roamify, Stixrs, LineCast Networks, Simbye, eSIMX, and others.
Telephony details vary by provider. GlobaleSIM issues a +1 number (US/Canada) with inbound and outbound voice, and inbound SMS. Roamify also uses a +1 number and supports inbound/outbound voice and SMS. Stixrs, LineCast, Simbye, and eSIMX all provide French +33 or Monaco +376 numbers, with full inbound/outbound voice and SMS support. RedEx eSIM offers local Cambodian +855 numbers (and also +61 Australia) that support inbound/outbound voice and SMS. Therefore, unless you choose a provider such as RedEx eSIM that supplies a local number, you will receive a foreign number for use while traveling in Cambodia.
