Our verdict
For most trips to Cambodia, a mid-size data plan on Simzora is the best balance of price and coverage. It roams on local partner networks with the widest reach across the country, connects the moment you land at Phnom Penh or Siem Reap, and you pay a plain per-GB rate instead of a vague unlimited promise. Install it over Wi-Fi before you fly and it is ready in minutes.

Around 3GB over a week is plenty if you lean on hotel and guesthouse Wi-Fi and mainly use Google Maps, WhatsApp and the odd search around Phnom Penh, Siem Reap and the temples at Angkor. Cafes and hotels across the tourist towns have Wi-Fi almost everywhere, so light users rarely burn through more.
Around 10GB covers most one to two week trips with daily social, maps across Phnom Penh, Siem Reap and the coast at Sihanoukville, and sharing photos. It is the sweet spot for the average traveller who is out and about but not streaming all day.
If you stream, tether a laptop or work remotely from Siem Reap or Kampot, look at a 20GB plan or an unlimited plan. Note that unlimited runs at full speed up to a daily allowance, so for steady heavy use a large fixed-data plan is often the cleaner choice.
Every Simzora plan is a plain data amount at an honest per-GB price. Here is the full standard range for Cambodia, with what each size actually suits.

See how it works
Turn on data roaming at arrival and get online. Your plan starts on its first connection in Cambodia, not at purchase.
No hype, just how the service actually behaves once you land.
Plans connect to local partner networks with the broadest reach in Cambodia, so you get fast LTE and growing 5G across Phnom Penh, Siem Reap near the Angkor temples and the coast around Sihanoukville. Coverage naturally thins in the Cardamom Mountains, the remote northeast and on the quieter island coves off Koh Rong, which is the network's limit rather than the eSIM's.
You buy a plain amount of data at a visible per-GB rate, not a fuzzy unlimited claim. That makes it easy to pick the right size for your trip and know exactly what you are paying for.
The QR code arrives by email in minutes, so you install over Wi-Fi before you fly and the line activates as soon as you reach Phnom Penh or Siem Reap airport. It is data-only, so keep your home SIM in the phone for bank OTP codes while WhatsApp keeps working over data.
