Our Final Recommendation
For the vast majority of travelers planning a trip to Cambodia, we recommend eSIM4.
It delivers the perfect balance of high-speed internet on top-tier networks like Smart, a wide range of plans to suit any itinerary, and the unique ability to add calls and SMS via the Yabb app.
Get eSIM4 For Cambodia →How To Make Phone Calls with Your eSIM
Most travel eSIMs like eSIM4 provide data-only plans. Here are your options for making calls:
Internet-Based Apps
You can use apps like WhatsApp, FaceTime, or Skype over your eSIM data connection. These work well for calling other app users, though you won’t be able to reach local businesses, landlines, or people who don’t have the same app installed.
Voice-Enabled eSIMs
Some eSIMs offer voice calling with a dedicated phone number, though these are less common and typically cost more than data-only plans. You’ll need to manage dual SIM settings and will receive a foreign number that may be difficult to share with contacts.
Using Yabb with Your eSIM
Yabb (owned by eSIM4) is a calling app designed to work with your eSIM data plan. Simply download the app and you can:
- Call any landline or mobile number in Cambodia or worldwide (200+ countries)
- Reach local businesses, hotels, and restaurants for bookings
- Pay as you go with transparent pricing and no contracts
- Enjoy clear call quality over your existing data connection
Available on iPhone App Store and Google Play, Yabb integrates with your eSIM4 data to provide calling functionality without needing a voice-enabled eSIM or relying on the other party having specific apps installed.

Sending text messages internationally is easy with eSIM, and if you’re using eSIM4, you have the option to use Yabb for SMS messaging as well. Most esim providers offer data-only plans, but Yabb provides a dedicated SMS service that works perfectly with your travel eSIM setup.
Yabb SMS Messaging Service
Yabb allows you to send and receive text messages to 200+ countries, making it ideal for staying in touch with family while you’re using data from your eSIM in Cambodia. Here’s what you need to know:

Learn More About Yabb SMS →Why Use an eSIM in Cambodia?
Buying a physical SIM card in Cambodia can sometimes be a hassle, involving language barriers and time spent at airport kiosks.
The eSIM advantage: Travel eSIMs bypass this completely. Because you are roaming on partner networks (like Smart or Metfone), no local identity verification (KYC) is typically required for data-only plans. You simply scan, activate, and connect the moment your plane touches down at the airport. No need to worry about losing your original embedded sim or main card.
