A trip to Cambodia usually combines several stops: the Angkor temples near Siem Reap, the capital Phnom Penh and the southern beaches, reached by bus, plane or boat. Ride-hailing, tuk-tuks, guesthouse bookings and transport tickets are easier to handle on the spot than by hunting for Wi-Fi along the way. An eSIM is installed at home in advance, so after landing you only switch mobile data on.
You can buy an eSIM for Cambodia online right on this page from 3 500 ₸: choose a data plan, pay by card and get the QR code within minutes. An eSIM is a digital SIM card — it installs on your phone with no plastic card and no visit to a phone shop.
The eSIM connects to local mobile networks, so you have data wherever they have coverage — Phnom Penh and the rest of the country.
Roaming in Cambodia with a Kazakh carrier is usually far more expensive, and roaming data runs out fast. With a Funsim eSIM you pay a fixed price for a data package and keep your home SIM in the phone for calls and bank SMS — roaming on it can stay off.
If your phone does not support eSIM, you can buy a regular physical SIM card with data for Cambodia at a Funsim point of sale: at Almaty and Shymkent airports, or at our offices in Almaty — 130/1 Abay St and 1 Pozharsky St. Handy if you remember about the internet right before departure.
A route through the country rarely stays in one city: first Siem Reap, then the road to Phnom Penh, then the coast or the islands. One profile for the whole country saves you from buying a new card in every town. See the plans above for terms and data amounts; if you continue across Southeast Asia, it is worth comparing the regional plans.
On the road you need internet constantly but in small doses: a pin for a tuk-tuk driver, a message to the guesthouse host, a translated menu, a bus timetable check. Your main SIM stays in the phone for calls and bank SMS. Most plans have no calls or SMS, so messengers are the easiest way to reach guides and drivers.

| Home number | Stays for calls and banking | Stays | Usually a second SIM or a swap |
| Several cities in one trip | One profile for the country | Depends on operator terms | Yes, but buying takes time |
Cities and popular tourist areas are covered much better than the countryside, islands and forest regions. Here is where travelers go most often and where data matters most.
The country's main tourist hub. The temples are spread over a large area, so most visitors hire a tuk-tuk or a car for the day and check the map as they go. Data is needed for navigation, contact with your driver and booking accommodation. Many people head to Angkor Wat for sunrise and leave in the dark, so a connection set up in advance really helps.
The capital stands where the Mekong and Tonle Sap rivers meet. The Royal Palace, National Museum, markets and riverfront are fairly close together, but people usually ride between them by taxi or tuk-tuk. Ordering through an app is easier than haggling on the street, and a map helps you make sense of the street numbering.
A seaside city on the Gulf of Thailand and the main port for boats to the islands. Mobile data helps you check ferry timetables, book rooms and contact your hotel if a departure is moved because of weather. The day before sailing, save your tickets and contacts on your phone.
Island holidays with bungalows, beaches and few roads. Coverage here is less predictable than in the cities and may depend on the bay and the weather. Do not count on a steady signal in every bungalow: download an offline map, save your booking and agree the transfer time with your hosts in advance.
Quiet towns in the south known for the river, pepper and the crab market in Kep. People come by bus or car from Phnom Penh and Sihanoukville. Data is useful for ordering transport back, finding a cafe from reviews and booking a room on the way without losing time.
A city in the northwest with French-era buildings, a market and trips to nearby villages. Visitors usually arrive from Siem Reap or Phnom Penh and then get around by tuk-tuk or scooter. For such trips it helps to have a map and a way to reach your driver quickly if you miss each other in the countryside.
A large lake near Siem Reap with boat tours. Coverage on the water and in the villages can be unstable, so save important tickets and contacts beforehand. These trips are usually arranged by a hotel or local guide, and on the tour you mostly take photos rather than sit online.
Northeastern provinces with hills, waterfalls and rural roads. Towns are covered, but outside settlements the signal can drop. If you plan such a trip, download offline maps, save your guide's contact and keep spare battery, because a phone searching for a network drains faster.
A few services are enough for the trip: transport, maps and messengers. Install them at home while you have Wi-Fi.
A popular service for ordering taxis and tuk-tuks in big cities across Southeast Asia. In Cambodia it is used in Phnom Penh and Siem Reap. The price is usually visible before the ride, and you do not need to explain the address to the driver.
A local app for ordering tuk-tuks and taxis. It is handy as a backup when one service takes a long time to find a car. Check that the confirmation code arrives on your main SIM when you register.
Works in cities and on main roads, and shows reviews and opening hours. Download an offline map of the region before a trip to the islands or the countryside.
Helps with Khmer signs, especially outside tourist areas. Download Khmer for offline use and point the camera at signs and menus to read them.
Guesthouses, guides and drivers are usually reached through messengers. Many prefer them to calls, especially if your plan has no voice service.
Helps you find a hotel or guesthouse along the way and keep the booking confirmation. Keep the confirmation on your phone instead of searching for an email on arrival.
Check that your phone supports eSIM and is not carrier-locked. You can see this in the settings or on the manufacturer's website.
Choose a Cambodia plan above and pay by card on the site. No passport is needed. If you are also visiting neighboring countries, look at the regional plans.
Install the eSIM at home by QR code, the quick install button or manually while you have Wi-Fi. Then you will not need to look for a network at the airport.
After landing in Phnom Penh or Siem Reap, select the eSIM as the mobile data line and switch on data roaming for that line.
Keep your main SIM for calls and bank SMS, but turn off mobile data on it so traffic does not go through roaming.
If the package runs out, buy extra data on the site. Hotspot for a laptop is available in plans where it is allowed; see the conditions on the plan page.
Before heading to the islands or the countryside, download offline maps and save your bookings and contacts: the signal there can drop, and that is normal.
