Cambodia eSIM FAQs
Absolutely! ZenSim’s eSIMs work in over 200 countries, and Cambodia is one of them. We also have regional eSIMs that cover several nations on a single plan - check out our Travel eSIMs page for details.
Absolutely - using a travel eSIM beats roaming in Cambodia for several reasons:
Cost Efficiency: Our Cambodia local data rates are much cheaper than pay-as-you-go roaming fees.
Instant Activation: No need to wait for a SIM card; your eSIM goes live as soon as you land.
Data Visibility: Monitor exactly how much you’ve consumed, so there are no hidden surprises on your bill.
No, these eSIMs only provide data access and do not assign you a phone number. To make calls, please use internet - enabled apps such as WhatsApp or FaceTime.
The eSIM activates when you touch down in Cambodia — if you’ve already installed it, it should connect automatically.
Installing while already in Cambodia works too; it will start as soon as you complete setup.
If you experience connection issues, check our eSIM Troubleshooting Guide or reach out to our support team.
Our Cambodia travel eSIMs are purely data - no native voice or SMS services are included. If you need calling, use an internet - based app like WhatsApp or Skype over your data connection.
Your eSIM will activate automatically once you arrive in Cambodia. We advise installing your Cambodia Travel eSIM before you travel (installation is distinct from activation).
To install, just scan the QR code we send or install via the ZenSim app over WiFi. On landing in Cambodia, the eSIM will switch on by itself.
If you have any problems, check our eSIM Troubleshooting Guide or contact us 😊
Of course. Open the ZenSim app and log in. From there, you can choose to top up your eSIM with additional days or gigabytes.
Just select the top-up plan you need (for example, another 30 days or a plan of 10GB) and complete your purchase — it’s instant.
Not exactly. Once your Cambodia eSIM is active, it’s tied to that country.
If you're visiting more than one place, our regional Travel eSIMs offer broader coverage so you can roam freely across multiple destinations.
Yes! Your Cambodia eSIM can be installed as early as 30 days before you travel. It won’t start until you touch down in Cambodia.
Installing beforehand means no setup stress on arrival, and it won’t use any data or days until you land.
If you get an activation warning on iPhone when installing before arriving, that’s normal — check our eSIM Troubleshooting Guide for details.
Connectivity Troubleshooting: Check our troubleshooting guide if your eSIM won’t connect. Still stuck? Hit up our support team and we’ll get you back online fast.
eSIM Installation Help: For help setting up your eSIM, visit our installation guide, or simply contact us - we’re happy to assist.
Other Inquiries: Have another issue? Head to our contact page and we’ll respond ASAP.
Nope — the eSIM waits for you to land in Cambodia before beginning data usage or counting plan days, unless of course you're already in Cambodia then yes it will start using data immediately.
We advise installing before departure over WiFi so you can be connected as soon as you land on the tarmac.
For any connection hiccups, check out our eSIM Troubleshooting Guide or get in touch.

Top 3 Things to Do in Cambodia
1. Explore Angkor Wat
Angkor Wat, located in Siem Reap, is the largest religious monument in the world and a UNESCO World Heritage site. This ancient temple complex, built during the Khmer Empire, is an architectural masterpiece filled with intricate carvings and towering spires. Sunrise is the best time to visit, as the temple is bathed in golden light. Wander through the surrounding ruins, including Ta Prohm, where tree roots intertwine with stone walls, creating a mystical atmosphere.
2. Cruise the Tonlé Sap Lake
Tonlé Sap Lake is Southeast Asia’s largest freshwater lake and a hub of life for many Cambodians. Take a boat tour to visit floating villages like Kompong Phluk, where homes and schools are built on stilts. The lake offers a glimpse into local life and culture, as well as opportunities to spot unique wildlife. A sunset cruise on Tonlé Sap is a serene experience not to be missed.
3. Relax on Koh Rong Island
Koh Rong Island is a tropical paradise with white sand beaches and crystal-clear waters. Located off the coast of Sihanoukville, this island is perfect for relaxing, snorkelling, or diving. The bioluminescent plankton that lights up the water at night adds a magical touch to your visit. Koh Rong offers a serene escape from the hustle and bustle of mainland Cambodia.
