“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.”

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 in Cambodia can be found from five providers: GlobaleSIM, Roamify, Orange Travel, Earth Esim, and TravelKon. Prices start around $4 for a 1 GB, 7‑day package and rise to about $105 for a 20 GB, 365‑day bundle, with validity periods ranging from 7 days to 365 days.

All of these plans offer inbound and outbound voice calls, and most provide inbound and outbound SMS. However, the phone numbers supplied use dialing codes that are not Cambodia’s local code (the local code is +855); instead they use +1 or +33. This means the numbers are foreign to Cambodia, so if a local Cambodia phone number is required travelers must seek a local SIM or use data‑based VoIP services.
