“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.”

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.

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 from several providers. The list includes GlobaleSIM, Roamify, Earth Esim, Airhub, Simbye, eSIMX, RedEx eSIM, Orange Travel, and Global Starlink. Every listed plan offers inbound and outbound voice (except those marked otherwise) and inbound or inbound‑/outbound SMS, although most give a phone number from a foreign dialing code—such as +1, +33, or +376. The only plans that provide a local Cambodia number (dialing code +855) are supplied by RedEx eSIM, which also supports full voice and SMS. Prices for these plans start around US$4 for a 7‑day bundle and can rise to about US$105 for a 365‑day premium package, with validity periods ranging from 7 days to 365 days.

Travelers should confirm that the number type works for their intended use in Cambodia and that any necessary SMS or voice services are not restricted by local regulations. While the plans provide data and, in many cases, calls and text messages, some destinations may block certain apps or VoIP services. Always double‑check the specific plan’s specifications and local usage policies before purchasing.
