eSIM for Cambodia

Your eSIM connects to Metfone the moment you land. Metfone is owned by Viettel and has the widest tower network in Cambodia. It is the network you want if you plan to leave the big cities and head into the countryside.

You do not pick the network by hand. Your phone finds Metfone on its own and stays on it. If signal ever drops in a remote spot, just turn airplane mode on for a few seconds and off again. That forces your phone to search and lock back on.

In Phnom Penh you will get strong 4G almost everywhere, and 5G in many central areas. Speeds in the city often land between 15 and 40 Mbps. That is fast enough for video calls, maps, Grab rides, and uploading photos without waiting.

Siem Reap is the same story. Around Pub Street, the Old Market, and most hotels the signal is solid. Speeds of 10 to 25 Mbps are normal here, which covers everything a traveler does day to day.

Most of the Angkor Archaeological Park has working 4G. You can pull up a map, look up temple history, and post a photo from Angkor Wat or Bayon without trouble.

The dead spots come when you walk deep inside the larger temples or into the jungle around the far ruins like Ta Prohm. The thick stone and tree cover block the signal. Download your map and any temple notes before you go in, and you will be fine.

Sihanoukville, Kampot, and Kep all have good coverage in town. Along the main highways between cities you will keep a usable 4G signal most of the way, though it can dip to slower speeds on quiet rural stretches.

The islands are the weak point. On Koh Rong and Koh Rong Sanloem the signal is patchy and slow once you leave the main beach areas. Many islands lean on cafe and hotel wifi instead. Plan for the islands to be your offline time, and grab any boat times or bookings before you sail out.

Light users who mostly check maps, messages, and a bit of social media do fine on a small plan. The 1 GB for 7 days plan at $1.49 covers a short city break for this kind of use.

Most travelers fall in the middle. If you use maps daily, post photos, and make some video calls, the 5 GB for 30 days plan at $5.60 is a comfortable fit for a week or two on the ground.

Heavy users who stream, work online, or share a hotspot should go for the 10 GB for 30 days plan at $10.22. That gives you room to tether a laptop or a travel partner without watching the meter.

After you buy, you get an email with a QR code. Install it while you still have wifi at home, but do this within a day or two of your trip. On an iPhone go to Settings, then Cellular, then Add eSIM, and scan the code. On Android open Settings, then Network, then SIM, then add an eSIM and scan.

Once it is installed, turn on data roaming for the new plan and set it as your data line. Your countdown and your data only start when the eSIM first connects to Metfone in Cambodia, so installing early does not waste any days.

You can buy a physical SIM at the Phnom Penh, Siem Reap, or Sihanoukville airport counters, but that means queuing, showing your passport, and swapping out your home SIM. The eSIM skips all of that and works the second you land.

Home roaming is the option to avoid. It often costs many dollars a day for slow data. With a cheapest plan starting at just $1.49, this eSIM is a fraction of the price and far simpler than juggling tiny plastic cards on the road.
