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.

Cambodia travel guide

Enjoy your Cambodia vacation

Cambodia is a Southeast Asian gem where ancient temples meet vibrant culture, offering travellers an unforgettable journey through history and natural beauty. From the awe-inspiring Angkor Wat complex to the bustling markets of Phnom Penh and the serene beaches of Sihanoukville, Cambodia delivers diverse experiences that captivate every visitor. The warmth of the Cambodian people and the incredible value for money make this destination truly special. Stay connected throughout your adventure with a uPhone eSIM, ensuring you can navigate temples, share moments, and communicate seamlessly from the moment you land.

Top attractions in Cambodia

Cambodia boasts an impressive array of attractions spanning ancient archaeology, cultural heritage, and natural wonders. Whether you're seeking spiritual enlightenment at sacred temples or relaxation by turquoise waters, Cambodia delivers unforgettable experiences.

  • Angkor Wat — The world's largest religious monument and a UNESCO World Heritage site, this 12th-century temple complex is a breathtaking masterpiece of Khmer architecture.
  • Tonlé Sap Lake — Southeast Asia's largest freshwater lake, famous for its floating villages, diverse wildlife, and spectacular sunsets.
  • Phnom Penh — Cambodia's vibrant capital city featuring the Royal Palace, Silver Pagoda, and bustling markets alongside modern restaurants and nightlife.
  • Sihanoukville — A coastal paradise offering pristine beaches, island hopping opportunities, and water sports for relaxation and adventure.
  • Battambang — Cambodia's second-largest city known for its French colonial architecture, bamboo train rides, and thriving art scene.

Popular foods to try in Cambodia

Cambodian cuisine is a delicious blend of flavours influenced by Thai, Vietnamese, and Chinese cooking traditions, emphasizing fresh ingredients and aromatic herbs. Street food and local restaurants offer authentic dishes at incredibly affordable prices, making culinary exploration a highlight of any visit.

  • Nom Banh Chok — A fragrant fish curry noodle soup served with fresh vegetables and herbs, considered Cambodia's national dish.
  • Amok — A creamy curry dish made with fish or chicken, coconut milk, and spices, traditionally cooked in banana leaves.
  • Lok Lak — Tender marinated beef stir-fried with vegetables and served with a tangy lime-based dipping sauce.
  • Samlor Machu Teung — A refreshing sour soup combining tamarind, pineapple, and fresh fish with vibrant herbs and spices.
  • Num Pang — A beloved street food sandwich filled with grilled meat, pâté, pickled vegetables, and fresh herbs served on crusty bread.

Best time to visit Cambodia

The best time to visit Cambodia is from November to February, when the weather is cool and dry with minimal rainfall, making it ideal for exploring temples and outdoor activities. During these months, temperatures range from 20-30°C, and visibility at Angkor Wat is exceptional for photography and sightseeing.

The monsoon season from May to October brings heavy rainfall and higher humidity, but offers lush green landscapes and fewer tourists. March to April is extremely hot and humid before the rains arrive. If you don't mind the heat and occasional showers, visiting during shoulder seasons can mean better deals and a more authentic local experience.

What to pack for your visit to Cambodia

Cambodia's tropical climate and temple exploration require thoughtful packing to stay comfortable and respectful. Prepare for heat, humidity, occasional rain, and temple dress codes when planning your luggage.

  • Lightweight, breathable clothing — Cotton and linen garments help you stay cool in Cambodia's intense tropical heat and humidity.
  • Respectful temple attire — Pack sarongs, lightweight pants, and shirts with covered shoulders to comply with dress codes at Angkor Wat and other sacred sites.
  • High SPF sunscreen — The equatorial sun in Cambodia is intense; protect your skin with SPF 50+ sunscreen and reapply frequently.
  • Comfortable walking shoes — Sturdy, breathable shoes are essential for navigating temple grounds and exploring uneven terrain.
  • Rain jacket or poncho — A lightweight, packable rain cover is crucial for Cambodia's unpredictable tropical downpours, especially during shoulder seasons.
  • Your uPhone eSIM — Stay connected throughout Cambodia with seamless coverage from major local networks including Cellcard, Smart Axiata, and Metfone, ensuring reliable data and calls wherever you explore.

Frequently Asked Questions

Everything you need to know about your 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.
