Cambodia eSIM
data from $2.79.

Looking for an eSIM for Cambodia? Slashtel offers data only eSIM plans from $2.79 that connect to Metfone and Cellcard 4G networks. No local number, no calls or SMS. Just mobile data for maps, messaging and booking your next bus. Install it before you fly and stay connected from Angkor Wat to Phnom Penh.

Choosing an eSIM for Cambodia

What matters most is coverage on the main networks, enough data for your trip, and a validity period that matches your stay.

When readers ask what is the best eSIM for Cambodia, the answer depends on your route and how long you are staying. Here is what to check:

• Coverage on Metfone and Cellcard. These are the two networks your eSIM will connect to. Both have good coverage in cities and tourist areas. Your eSIM selects the network automatically, so you do not need to switch anything manually.
• Enough data for your trip. Cambodia is a popular backpacking destination, and you will likely use data for maps, messaging, and booking transport. Choose a plan with a buffer so you do not run out mid journey.
• Validity period. Plans last 7, 15 or 30 days. Pick one that covers your whole stay. If you are crossing borders, remember the plan is only valid in Cambodia.
• Hotspot support. All Slashtel eSIM plans allow you to share your data with other devices, such as a laptop or a travel companion's phone. This is useful if you need to work or if you are travelling with someone who does not have a plan.
• Install before you fly. Install the eSIM on your phone before departure. You need an internet connection to install it, and doing it at home avoids relying on airport Wi-Fi. Once installed, you can turn it on when you arrive in Cambodia.

Networks and coverage in Cambodia

Your eSIM connects to Metfone and Cellcard, the two main mobile networks in Cambodia, with 4G speeds. Coverage is strongest in cities and tourist areas.

Metfone and Cellcard both operate extensive networks across Cambodia. In Phnom Penh, Siem Reap (the gateway to Angkor Wat), and other towns, you can expect reliable 4G coverage. On popular backpacking routes, such as the coast and islands, coverage is generally good in populated areas but can be weaker in remote or rural locations. Your eSIM will automatically select the stronger network available at your location, so you do not need to manually switch. This is useful if you are moving between areas. The eSIM is data only, so you will not be able to make traditional phone calls or send SMS. However, you can use data based services like WhatsApp, FaceTime, and other messaging apps for calls and texts.

How much data you need

Most travellers need between 1GB and 3GB for a typical trip, but heavier users or those who need hotspot should consider 5GB or more.

Data usage depends on how you travel. Here are typical trip types and suggested data amounts based on Slashtel's recommended plans:

• One week: 1GB for 7 days. Suitable for light use: maps, messaging, and occasional web browsing.
• Two weeks: 2GB for 15 days. A good balance for moderate use, including social media and some video.
• One month: 3GB for 30 days. For longer stays with regular but not heavy data use.

If you plan to use your phone as a hotspot, stream video, or upload many photos, choose a larger plan such as 5GB, 10GB, or 20GB. These are available for 7, 15, or 30 days. You can check live prices for these plans in the table above. Remember that data is consumed whenever you use the internet without Wi-Fi, so it is better to have a little extra than to run out.

Install it before you fly

Install your Cambodia eSIM before you leave home so you can activate it as soon as you land.

You need an internet connection to install the eSIM. Doing it before you travel means you can avoid relying on airport Wi-Fi or finding a local SIM shop. The installation process is straightforward: you will receive a QR code or activation details by email after purchase. Scan the QR code with your phone's camera and follow the prompts. For detailed steps, see our guide on how to install an eSIM on iPhone and Android. Before you buy, make sure your phone is eSIM compatible by checking our guide is my phone eSIM compatible. Once installed, keep the eSIM turned off until you arrive in Cambodia. When you land, turn it on and enable data roaming if required. The eSIM will connect automatically to Metfone or Cellcard.

Calls, texts and your home number

The Cambodia eSIM is data only, so you cannot make traditional calls or send SMS with it. Keep your home SIM active for calls and bank codes.

Because the eSIM provides only data, you will not have a local phone number. To make calls or send texts, you can use apps like WhatsApp, FaceTime, or Skype over data. These work well for staying in touch with family and friends. For important calls, such as to your bank for verification codes, you should keep your home SIM in your phone. Most phones allow you to use two SIMs at once: your home SIM for calls and texts, and the eSIM for data. Make sure your home SIM is set as the default for calls and SMS, and the eSIM as the default for mobile data. This way, you can receive bank codes and make calls without incurring data charges on your home plan. Note that your home provider may charge for calls and texts according to your plan.
