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.
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.
Airalo does not have a truly unlimited data eSIM available for Cambodia. The plans labeled “Unlimited” on Airalo’s catalogue actually provide a capped allowance of 3 GB per day; once that limit is reached the connection speed drops to 1000 kbps. Travelers who need more data without daily caps can opt for fixed‑data plans, such as the Asialink 100 GB plan that covers 180 days or the Connect Cambodia 50 GB plan that lasts 30 days. These plans offer larger, fixed quantities of high‑speed data before any speed reduction occurs, and may be more cost‑effective for heavy data users.
Airalo does not provide a Cambodian eSIM that includes a phone number or SMS capability. The available plans are data‑only and do not support inbound or outbound voice calls or text messages.
Travelers who need voice communication or messaging can use data‑connected VoIP applications such as WhatsApp, Telegram or iMessage. These services work over a data connection and do not require a local phone number or traditional SMS support.
Airalo offers 18 single‑country plans and 32 multi‑country plans for Cambodia, covering a price range of $4 to $89 and data caps from 1 GB up to 100 GB. The majority of the single‑country plans are fixed‑data packages, while a small portion of the multi‑country plans provide daily data caps.
