What you get with a Cambodia eSIM
Every plan is data-only and prepaid. You'll receive a QR code by email within minutes of purchase. Scan it before or after you land, and your device connects to mobile networks across Cambodia. Plans start with 100MB valid for 7 days and scale up depending on how long you're staying and how much data you need.
These are data plans, so you won't receive a Cambodian phone number. You can still use WhatsApp, Telegram, Google Maps, and any other app that runs over a data connection. For voice calls, use an internet calling app. Your plan works on 4G/LTE or 5G where the underlying network and your device support it.
How to set up your Cambodia eSIM
Before you buy, check that your phone supports eSIM. Most iPhones from the XS onward and recent Samsung, Google, and other Android flagship models do. Your device must be carrier-unlocked. Once you complete your purchase, the QR code arrives by email. You can install it any time before your trip or on arrival.
Open your phone's settings, find the option to add a cellular plan or mobile network, and scan the QR code. The eSIM installs in under a minute. If you install it before departure, keep it turned off until you land in Cambodia. Once you arrive and switch it on, it will register and you'll have data.
Using mobile data across Cambodia
Coverage is strongest in Phnom Penh, Siem Reap, Sihanoukville, and Battambang, extending along National Routes 1, 4, 5, and 6. You'll have reliable connectivity around Angkor Wat and the main temple complexes, on the bus between cities, and in most towns that see tourist traffic. Remote provinces and rural areas between highways may see reduced signal or drop to slower speeds.
Typical traveller data use: navigation apps consume 5 to 10MB per hour, messaging stays under 1MB per day, and an hour of social media browsing runs 50 to 100MB. Uploading photos and videos will drain your allowance faster. If you plan to stream or video call frequently, choose a larger plan. Public WiFi is common in hotels and cafés but a local data connection means you stay reachable on the move.
Frequently asked questions
Will my Cambodia eSIM work in Siem Reap and Angkor Wat?
Yes. The eSIM works across Cambodia, including Siem Reap and the Angkor Archaeological Park. Coverage is strong in town and around the temple sites, so you can navigate, translate, and share photos without interruption.
Can I use this eSIM in my phone and my tablet?
No. Each eSIM is locked to one device. If you want data on a tablet or second phone, buy a separate plan for that device and install its QR code there.
Do I need to remove my home SIM card?
No. If your phone has a physical SIM slot, leave your home SIM in place. The eSIM runs alongside it. You choose which line to use for data in your phone's settings.
When does my plan validity start?
Validity starts when the eSIM first connects to a mobile network in Cambodia, not when you buy or install it. Install before you travel and switch it on after you land.
What happens if I run out of data?
Your connection stops when you exhaust your allowance or your validity period ends. You can buy a new plan and install it as a second eSIM, but you cannot top up an existing one.
