Frequently asked questions — Cambodia eSIM

What is a Cambodia eSIM and how does it work?

A Cambodia eSIM is a digital SIM card that gives you instant mobile data access across Cambodia without a physical SIM card. After purchase, scan the QR code to download a carrier profile onto your phone. When your device connects to a local network in Cambodia, your plan activates automatically.

How do I activate my eSIM for Cambodia?

After purchasing your Cambodia eSIM, scan the QR code from your email or Roamix dashboard to install the profile. We recommend installing before you travel on a stable Wi-Fi connection. When you arrive in Cambodia and your phone detects a local network, your plan activates and data begins automatically.

Can I keep my own phone number when using a Cambodia eSIM?

Yes. With a Roamix eSIM for Cambodia, your primary SIM card stays fully active. People can call and text you on your usual number as normal. The eSIM runs alongside your existing SIM in dual-SIM mode, with your home SIM handling calls and texts while Roamix provides affordable mobile data in Cambodia.

When should I install my Cambodia eSIM?

Install your Cambodia eSIM before you travel, at home on a Wi-Fi connection. The plan does not start counting down or consuming data until your device connects to a local network in Cambodia. Installing in advance means you step off the plane already connected with no airport setup required.

Will my phone work with a Cambodia eSIM?

Most modern smartphones support eSIM, including iPhone XS and newer, Samsung Galaxy S20 and newer, and Google Pixel 3 and newer. Your device must also be carrier-unlocked. Use our free eSIM Compatibility Checker to confirm both requirements in seconds before purchasing your Cambodia eSIM plan.

What network speeds can I expect in Cambodia?

Roamix partners with leading mobile network operators in Cambodia to deliver the best available speeds. 4G LTE is available across all supported areas, and 5G is available where local infrastructure supports it. Actual speeds depend on your location within Cambodia, local network load, and your device's band compatibility.

What happens if I run out of data while in Cambodia?

Roamix sends usage alerts at 50% and 80% of your data so you can plan ahead. If your data runs out in Cambodia, internet connectivity pauses with no automatic overage charges. You can top up additional data instantly from your Roamix dashboard without reinstalling your eSIM.

Can I get a refund if I don't use my Cambodia eSIM?

Roamix offers a 14-day refund window for Cambodia eSIM plans that have not been installed or activated. If your travel plans change, contact support@roamix.app within 14 days of purchase with your order number. Once a QR code is scanned and the eSIM profile installed, the plan is considered activated and refunds are not available.

What is the cheapest eSIM for Cambodia?

Our Cambodia eSIM plans start at $0.45 for the smallest data package. Larger plans offer a better per-GB rate and are ideal for longer trips or heavier data users. Browse all available Cambodia plans above to find the best option for your trip.

Do I need a SIM card for Cambodia?

No physical SIM card is needed for Cambodia if your phone supports eSIM, which most smartphones since 2018 do. A Roamix eSIM lets you download a digital carrier profile before you travel with no store visit, no card swap, and no waiting at the airport. Your home SIM stays active for calls and texts.

How much data do I need for traveling in Cambodia?

For a week-long trip to Cambodia, most travelers use 5-7 GB for maps, messaging, and social media. If you plan to video call, stream content, or work remotely, consider a 10-15 GB plan. Roamix offers flexible data packages to match your travel needs.
