Buy eSIM data plans for Cambodia
Your Cambodia eSIM is a prepaid data plan that connects your phone to local Cambodia networks at full speed the moment you land — a digital SIM you install before you fly, with no queues, no SIM swap and no roaming fees.
A Cambodia eSIM is a prepaid, data-only plan that loads onto your phone before you fly and switches on the moment you reach Phnom Penh International Airport. Instead of hunting for a SIM kiosk or paying roaming fees, you step off the plane already online, connecting to the local Metfone (Viettel) 4G network. From the arrivals hall you can open maps, order a tuk-tuk, message family back home, and check your booking while you wait for your bags. One scan before departure and you stay connected across the country without swapping out your physical SIM or losing your usual number.

Important cities in Cambodia
Phnom Penh · City guide
Phnom Penh
A Phnom Penh eSIM keeps you online as you move between the Royal Palace, the riverside promenade, and the central markets. Use mobile data to map your route, compare prices before you buy, and call a ride when the streets get busy. With coverage strongest in the city centre, staying connected here is simple, so you can share photos and check directions without searching for free WiFi.
Phnom Penh eSIM — online before you land →Siem Reap · City guide
Siem Reap
As the gateway to Angkor Wat, Siem Reap is where most temple visits start and end. A data plan for Siem Reap helps you book a guide, look up opening times, and find your way back to the old French quarter after a long day. In the evening, use mobile data to navigate the night market and message friends. Town coverage is reliable, though it can vary out among the ruins.
Siem Reap eSIM — online before you land →Sihanoukville · City guide
Sihanoukville
Sihanoukville pairs the beaches with the seafront and serves as the gateway to the islands. A Sihanoukville eSIM lets you check ferry times, share your location with travel companions, and post from the sand. Use mobile data along the seafront to plan your day, keeping in mind that signal can drop once you are out on the boats. Connecting before you leave the mainland keeps you covered for as long as possible.
Sihanoukville eSIM — online before you land →Battambang · City guide
Battambang
Battambang offers a slower pace, with its colonial-era town set along the riverside and easy access to the surrounding countryside. A data plan for Battambang is handy for translating menus, mapping a walk through the old streets, and arranging transport for a day trip. Use mobile data while you explore, remembering that coverage is steadiest in town and may thin out as you head into the countryside.

Frequently asked questions
Which mobile networks does the Cambodia eSIM use?
The Cambodia eSIM connects to the Metfone (Viettel) network on 4G. Coverage is strongest in city centres and main towns, and is more variable in remote and rural areas, which is normal for any network.
Will my eSIM work at the Angkor Wat temples around Siem Reap?
Coverage in Siem Reap town itself is generally strong, so you can book guides and look up the temples easily. Out among the ruins the signal can vary from spot to spot, so it helps to download maps or your itinerary while you still have a solid connection in town.
How is the signal on the islands off Sihanoukville?
Along the Sihanoukville seafront and on the mainland the signal is usually reliable. Once you head out to the islands, coverage can drop on the boats and in spots offshore, so connect and check anything you need, such as ferry times, before you leave the shore.
Will one Cambodia plan cover a multi-country trip?
This is a Cambodia-only plan and works just within Cambodia. If your trip also takes you to other countries in Southeast Asia, choose a regional eSIM that covers the wider area instead, so you stay connected across borders without switching plans.
When should I set up the eSIM before arriving in Cambodia?
Install the eSIM over WiFi a day or two before you fly, while you have a stable connection. Leave activation for when you arrive, so the plan is ready to switch on the moment you reach Phnom Penh International Airport and you are online before you even pick up your bags.
Can I keep my own number and use a hotspot in Cambodia?
Yes. The eSIM adds data alongside your usual SIM, so your home number stays active for calls and texts while the eSIM handles your data in Cambodia. Most phones can also share that data as a hotspot, which is handy for a laptop or a travel companion's device.
