Before you buy your Cambodia eSIM
Is my phone compatible?
Quick check: dial *#06# on your phone. If an EID number appears, your phone supports eSIM. It also needs to be carrier-unlocked.
How much data do I need?
A rough estimate based on typical use. Video and hotspot use the most data.

Guide to Staying Connected in Cambodia
Staying connected in Cambodia is a bit easier than other countries in Southeast Asia when traveling.
Best Areas For Coverage
Siem Reap, Phnom Penh, and Sihanoukville offer some of the best places to get internet connection in Cambodia. Also, many of the popular expat destinations such as Kampot, Kep, and Battambang, also have good coverage.
Reliable Networks
We partner with three of the top telecommunications companies in Cambodia, Smart Axiata, Cellcard, and Metfone. Smart and Cellcard have very fast speeds in the urban areas, while Metfone has wider coverage in rural areas and in the Cardamom Mountains.
Data Usage
Cambodia is a fantastic destination for digital nomads. Some things you may want to use data for include using PassApp or Grab (for ordering tuk-tuks) , Google Maps, and translation apps. Most travelers should have enough data for a standard two week trip with 10GB, but many remote workers prefer to have 20GB so they can hold multiple video calls.
Must See Spots
There are many incredible sights to see in Cambodia. These include, but are not limited to: witnessing the majesty of Angkor Wat, visiting the floating villages of Tonle Sap Lake, experiencing the glow-in-the-dark plankton beaches of Koh Rong Samloem, and riding the bamboo train in Battambang.
Avoid the Registration Process
In order to purchase a SIM card in Cambodia you will need to register with your passport at a local SIM card shop. This process can take up a lot of your time and can be very inconvenient. eSIM eliminates the need to register with your passport entirely and allows you to purchase your eSIM online and activate it before you arrive in the country, eliminating the need for you to waste time registering at the airport.
24/7 Support
Regardless if you are visiting ancient temples or island hopping in Cambodia, our 24/7 support team is there to help answer any questions or issues related to connecting or using your eSIM.
eSIM FAQs
Common questions about using eSIM in Cambodia
Does eSIM work in Cambodia? Visitor’s complete guide 2026
Yes — eSIM works in Cambodia in 2026 on Cambodia’s mobile networks (Smart Axiata, Cellcard, Metfone). An international eSIM like Esimy connects you to Cambodia 4G/LTE the moment you land — no SIM swap, no Cambodian passport registration, no kiosk visit.
What “eSIM works in Cambodia” actually means: any eSIM-capable phone (iPhone XS+, Pixel 3+, Galaxy S20+) installs an Esimy Cambodia eSIM as a second line. Your phone connects to local Cambodian networks via international roaming infrastructure — same way it would if you were roaming with your home carrier — but at Esimy’s flat single-country pricing instead of expensive home-carrier roaming fees.
Coverage you can expect: reliable 4G/LTE in Siem Reap (Angkor Wat), Phnom Penh, Sihanoukville and the popular expat hubs of Kampot, Kep and Battambang. Some remote jungle and island areas may drop to 3G — same as for any provider.
How to confirm before you buy: dial *#06# on your phone — if you see an “EID” alongside your IMEI, your phone supports eSIM. Order an Esimy Cambodia plan from esimy.net (starting from €3.49 / 1 GB / 7 days), install before flying, switch on data when you land. Connection time: typically 30 seconds.
Best eSIM for Cambodia — travel guide 2026
The best eSIM for Cambodia travel in 2026 is Esimy — single-country Cambodia plans starting from €3.49 / 1 GB / 7 days, with 4G/LTE coverage on Cambodia’s mobile networks via Smart Axiata, Cellcard and Metfone. No SIM swap, no roaming surcharge, no airport SIM hunt.
Esimy Cambodia single-country plans: €3.49 / 1 GB / 7 days, €8.99 / 3 GB / 30 days, €11.99 / 5 GB / 30 days, €19.99 / 10 GB / 30 days. Ideal for 1- to 4-week trips covering Siem Reap, Phnom Penh, Sihanoukville, Kampot and Battambang. Hotspot/tethering included on every plan.
Why Esimy beats picking up a local SIM at the airport: Cambodian local SIMs typically require passport registration, are mainly available at airport kiosks with surge pricing, and you have to find a carrier store to top up. With Esimy, the QR code arrives in your inbox before you fly — install on the plane, switch on data when you land at Phnom Penh International (PNH) or Siem Reap-Angkor International (SAI).
Why Esimy specifically for Cambodia: Esimy connects to Smart Axiata, Cellcard and Metfone for solid 4G/LTE coverage in cities and tourism circuits — Smart and Cellcard for fast urban speeds and Metfone for wider rural and Cardamom Mountains coverage. 5% cashback in Loyalty Points (1,000 points = €1) on every purchase, no expiration. 24/7 multilingual support. Top up directly from the Esimy app mid-trip.
