Choosing the Right eSIM for Your Trip

eSIM4 is our top pick, but every traveler has different needs. Here are the factors that matter when comparing eSIM services for Cambodia.

Factor Considerations Impact
Network Coverage Does the provider partner with major local networks like Smart or Metfone (Viettel)? Crucial for signal in both urban centers and rural areas.
Data Requirements Are you a light user, or do you require unlimited data for streaming? Estimate your needs to avoid overspending or running out.
Device Compatibility Is your smartphone compatible with eSIM technology? Ensure your phone supports eSIM before purchase.
Added Features Do you need a phone number for calls and texts? Most eSIMs are data-only; consider apps or specialized plans.
Cost Efficiency Don’t just look at the total price. Check cost-per-GB to ensure you aren’t overpaying.

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.

How To Send Text Messages

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:

Yabb SMS Features

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.

Frequently Asked Questions about eSIMs

Will my phone work with an eSIM in Cambodia?

Most smartphones manufactured after 2018 support eSIM technology. This includes iPhone XR and newer, Samsung Galaxy S20 and newer, and Google Pixel 3 and newer. Check your settings or dial *#06# to see if an EID number appears.

Can I use WhatsApp with a new eSIM?

Yes. When you switch to an eSIM for data, WhatsApp will ask if you want to keep your existing number. Select “Keep” and you can continue using your original account and contacts seamlessly.

How do I activate my eSIM?

After purchase, your provider will send you a QR code via email. Go to your phone settings, select “Add Cellular Plan,” and scan the QR code. You can also enter the details manually if needed.

Which network is best in Cambodia?

Smart typically offers the most extensive coverage across Cambodia, especially in rural areas and tourist hotspots like Siem Reap. Metfone is also a major reliable carrier. Our top recommendation, eSIM4, operates on these premium networks.

Can I share my data (Hotspot)?

Yes, most providers including eSIM4, Airalo, and Nomad allow tethering/hotspot usage. However, Holafly (Unlimited plans) restricts hotspot usage.

Are 4G and 5G speeds available in Cambodia?

Yes, 4G LTE is widely available in Cambodia, particularly in cities and tourist areas. 5G is rolling out but coverage is still limited compared to 4G.
