Provider Comparison for Cambodia
Each provider uses different local networks in Cambodia, resulting in different coverage quality and speeds. Here is how they compare.

Cambodia has 3 major mobile networks: Smart Axiata, Cellcard, Metfone. The best coverage comes from Smart Axiata, which covers 75% of the population with 4G technology.

How to Activate an eSIM in Cambodia
Setting up an eSIM for Cambodia is straightforward. Follow these steps to get connected before or upon arrival.
- 1
Check Device Compatibility
Make sure your phone supports eSIM. Most iPhones from XS onward, Samsung Galaxy S20+, and Google Pixel 3+ are compatible. Your device must also be carrier-unlocked to use an eSIM from a third-party provider in Cambodia.

Choose and Purchase a Plan
Compare plans above and select the one that fits your data needs and trip length. For a typical week-long trip to Cambodia, we recommend at least 3-5GB. Heavy users or longer stays should consider 10GB or unlimited options.

Install the eSIM Profile
After purchase, you will receive a QR code (or app installation link). Scan the QR code from your phone's Settings > Cellular > Add eSIM. Do this while connected to WiFi, ideally before your trip. The profile downloads in under a minute.

Activate at Your Destination
When you arrive in Cambodia, go to Settings > Cellular and enable your eSIM line for data. Set it as the primary data line. Your phone will connect to the local Smart Axiata automatically. The plan validity timer starts at this point for most providers.

Tips for Using eSIM in Cambodia
Download maps and content before your trip
Even with great coverage in Cambodia, having offline maps (Google Maps, Maps.me) saves data and works in areas with weak signal.
Monitor your data usage
Check your data usage in phone settings regularly. If you are running low, most providers let you purchase a top-up or additional plan without losing connectivity.
Choose the right network for Cambodia
Smart Axiata offers the best coverage in Cambodia. If you plan to travel outside major cities, prioritize providers that use this network.
Disable automatic updates
Turn off automatic app updates and cloud photo syncing to conserve data. These background processes can consume gigabytes without you noticing.
Test your eSIM before departure
Install the eSIM profile while on WiFi at home. Some phones let you verify the profile is correctly installed without activating the data plan, so you know everything will work when you land in Cambodia.
