Which Cambodia eSIM plan fits your trip?

Choose your Cambodia eSIM by matching the allowance and validity period to your trip, then compare the selected product details with the local network, band and speed references already shown on this page.

Start with the length of your stay, then allow for navigation, messaging, streaming and work use. Each option below is a plan size that is currently available for this destination.

Short trip

1 GB / 7 days

Best for: A short visit with maps, messages and occasional browsing.

This option pairs the 1 GB allowance with a stated validity period of 7 days.

Usage tip: Save maps before longer journeys and use Wi-Fi for large downloads.

Two-week trip

3 GB / 15 days

Best for: A stay of around two weeks with regular navigation and messaging.

The 3 GB allowance remains available across a stated validity period of 15 days.

Usage tip: Keep automatic app updates and cloud backups on Wi-Fi.

Longer or higher use

10 GB or more / 30 days

Best for: A longer stay or more frequent streaming, video calls or work use.

The 10 GB or more / 30 days profile provides a larger data pool than the short-trip options on this page.

Usage tip: Compare the allowance with your normal phone usage and monitor it during the trip.

Coverage in Cambodia

Coverage is concentrated in urban areas and along major roads; large portions of the Cardamom Mountains, northeastern Mondulkiri and Ratanakiri provinces, and the Tonle Sap lake area have limited or no service. Smart Axiata and Cellcard operate 3G on B1 (2100 MHz), which some older US-market phones lack.

How to check mobile coverage in Cambodia

The Cambodia mobile network source is linked below as a public network reference. Check the places on your itinerary where the source offers local detail, then confirm the network information for the selected eSIM product. The operator table on this page provides the country-level reference, while the selected product details identify which network information applies to your plan.

Accommodation and daily stops

Check your accommodation and the places you expect to visit in Cambodia. Indoor reception can differ from an outdoor map, so keep the property Wi-Fi details available as well.

Journeys between stops

Review the full route rather than checking only the arrival city. Save tickets, addresses and maps offline before longer road or rail journeys.

Borders and onward travel

Check the selected product scope for every country on your itinerary. Your Cambodia plan and a regional plan may have different included destinations and validity periods.

Phone compatibility in Cambodia

Compare your phone with 4G bands B1, B3, B5 and 5G bands n78 in the existing Cambodia network table. Support for more of the listed bands gives the phone more options when connecting, while the selected product, location and local network conditions determine the service available.

Set up the Cambodia eSIM for your trip

Keep the QR code and installation instructions available offline, and complete each step according to the selected product's instructions.

When validity starts: Validity-start rules can differ by product. Check the selected plan details before installation and travel.

  1. Confirm that your phone is unlocked and supports eSIM before purchase.
  2. Save the QR code or manual installation details somewhere you can reach without mobile data.
  3. Use reliable Wi-Fi to install the profile at the time recommended in the product instructions.
  4. When you are ready to use it, select the travel eSIM for cellular data and apply the stated roaming and APN settings.
  5. Keep roaming disabled on your home line if you want to avoid using its travel data.

How to Enjoy Cambodia

Cambodia offers a rich blend of ancient temples, lively cities, and serene coastlines. To make the most of your trip, plan at least three days around Angkor Wat to explore the major temples without rush. Phnom Penh and the surrounding countryside deserve two days for the Royal Palace and the sobering Killing Fields. Sihanoukville and nearby islands provide a coastal escape, but keep your stay brief as development can feel chaotic.

Stay in central Siem Reap for easy access to temples, and book a local guide for deeper historical context. Cambodian hospitality is genuine, so learn a few Khmer greetings like arun suor sdei for a warmer welcome. Avoid overpacking your itinerary; the tropical heat demands a slower pace. Stay hydrated and respect local customs, especially when visiting religious sites.

Top Attractions

Angkor Wat is the main draw, but the entire Angkor Archaeological Park is vast. Prioritise the Bayon’s stone faces, Ta Prohm’s tree-wrapped ruins, and the sunrise at the main temple. Buy a three-day pass to pace yourself.

Tonlé Sap Lake offers floating villages and stilted houses. Take a boat tour from Siem Reap to see daily life on Southeast Asia’s largest freshwater lake.

Phnom Penh combines the grandeur of the Royal Palace and Silver Pagoda with the heavy history of the Tuol Sleng Genocide Museum. Allow a full day.

Sihanoukville is a beach town with mixed appeal; consider nearby Koh Rong or Koh Rong Samloem for quieter sands.

Battambang has a laid-back feel with French colonial architecture and the bamboo train for a quirky ride.

Must-Try Foods

Nom Banh Chok is Cambodia’s answer to noodle soup, a rice noodle dish in a fish-based broth with herbs. Find it at street stalls for breakfast.

Amok is a steamed coconut curry, usually with fish or chicken, served in banana leaves. Its creamy, mild flavour is distinct from Thai curries.

Lok Lak is stir-fried beef served with lettuce, tomato, and a dip of lime and Kampot pepper. It’s a simple, satisfying street food staple.

Samlor Machu Teung is a sour soup with tamarind, pineapple, and fish, often eaten with rice. It’s a refreshing counter to Cambodia’s heat.

Num Pang is the Cambodian baguette sandwich, similar to Vietnamese banh mi but with local fillings like grilled pork and pickled vegetables. Street vendors sell them cheaply.

Best Time to Visit

Cambodia has two distinct seasons. The dry season from November to February is the most comfortable, with cooler temperatures and minimal rain. This is the peak time for visiting Angkor Wat and exploring the temples without muddy paths or afternoon downpours.

During the wet season from May to October, expect heavy but usually short-lived rain showers. The countryside turns lush and the rice paddies are lively, but some roads in rural areas become difficult. Tonlé Sap Lake is at its highest, making boat trips more accessible.

March and April are the hottest months, with temperatures often exceeding 38°C. If you travel then, plan temple visits for early morning and late afternoon, and carry plenty of water.

Packing Essentials

Lightweight, breathable clothing is non-negotiable. Cotton and linen help you cope with the tropical humidity. Pack long trousers and tops for temple visits; shorts and sleeveless tops are not appropriate at Angkor Wat and other sacred sites.

High SPF sunscreen and a wide-brimmed hat are essential for sun protection. The sun is intense even on cloudy days.

Comfortable walking shoes are vital for temple ruins with uneven stone steps. Sandals are fine for towns but not for climbing.

A rain jacket or poncho is useful if you travel during the wet season. Sudden downpours are common.

A travel eSIM ensures reliable connectivity. Prepare an offline map app and download a translation app for Khmer phrases.

Common questions about travel eSIMs

Answers to the questions travellers most often ask about using an eSIM overseas, from choosing a data plan to setting up before departure. Cambodia eSIM

Coverage is concentrated in urban areas and along major roads. Large parts of the Cardamom Mountains, northeastern Mondulkiri and Ratanakiri provinces, and the Tonle Sap lake area have limited or no service. You should not rely on connectivity in those regions.

Smart Axiata and Cellcard operate 3G on B1 (2100 MHz), which some older US-market phones lack. Your phone may still connect to their 4G networks (B1, B3, B5) or 5G (n78) if supported. Without 3G fallback, coverage gaps may be more noticeable in rural areas.

Your eSIM will connect to one of the three local operators: Cellcard, Smart Axiata, or Metfone. All three offer 4G on bands B1, B3, and B5, and 5G on n78. The specific network depends on signal strength and roaming agreements at your location.

This eSIM is for Cambodia only and does not include coverage in neighbouring countries such as Thailand, Laos, or Vietnam. If you cross the border, you will need a separate eSIM or plan for that country to maintain service.

Local SIM cards in Cambodia often require passport registration. With this eSIM, no local ID or registration is needed. You can install it before you travel and activate it upon arrival without visiting a store or showing documents.

Compare 1 GB / 7 days, 3 GB / 15 days and 10 GB or more / 30 days. Use the shorter profiles for lighter maps and messaging use, then compare the larger allowance for streaming, video calls or work apps.

The start rule is product-specific. Review the selected plan details before installing it so you know whether any action is required before arrival.

Save the QR code, manual installation details, APN guidance and the support instructions supplied with the selected plan.
