Cambodia eSIM

 This specific plan is valid only within Cambodia. This is the most important question for Southeast Asia backpackers. If you enter from Bangkok (Thailand) or cross into Ho Chi Minh City (Vietnam), your connection will stop. For a seamless "Banana Pancake Trail" journey, we highly recommend our Asia Regional eSIM, which covers Cambodia, Thailand, Vietnam, and Laos with one single plan. 

Yes, absolutely. You will have reliable 4G/LTE coverage throughout the entire Angkor Archaeological Park, including Angkor Wat, Bayon, and Ta Prohm (the "Tomb Raider" temple). This allows you to use Google Maps to navigate between temples, check their history online, or upload your sunrise photos instantly without waiting to get back to your hotel in Siem Reap. 

To ensure the best connection in a developing country, our eSIM connects to Cambodia's top-tier providers, typically Cellcard or Smart. These networks offer the most extensive coverage, ensuring you stay connected whether you are in the capital Phnom Penh, the tourist hub of Siem Reap, or the coastal towns of Sihanoukville and Kampot. 

Planning the trip? See our Cambodia eSIM plans, install in one tap before you fly, and land online. Free VPN included.

It varies. Coverage on the islands (Koh Rong and Koh Rong Samloem) is improving but can be inconsistent. You will find reliable 4G signal in the main tourist villages and guesthouse areas. However, signal may be weak or non-existent on remote beaches or during boat trips. It is perfect for messaging and social media, but we recommend downloading movies offline before you go. 

Yes. Grab is the essential app in Cambodia (there is no Uber) for ordering Tuk-Tuks and taxis, especially in Phnom Penh and Siem Reap. Our eSIM provides fast, low-latency data, ensuring you can book a ride from the airport, track your driver in real-time, and avoid haggling over prices. 

 Yes. PassApp is the most popular local app for booking rickshaws and tuk-tuks at fair, fixed prices (often cheaper than Grab), and it requires active mobile data to work. 

 Yes. Coverage is excellent in these southern provinces, allowing you to share photos instantly while visiting the famous Kampot pepper farms or the Kep crab market. 

 Yes. You will generally have strong signal at the main tourist docks and floating villages like Chong Kneas or Kampong Phluk, though connection may drop in the middle of the massive lake. 

 Yes. Battambang has reliable 4G LTE coverage, so you can live-stream or upload videos while riding the famous Norry (Bamboo Train) through the rice paddies. 

Look up your phone’s exact model number with the manufacturer to see if it’s listed as compatible, and make sure your phone is not carrier-locked. Seeing an EID number or an “Add eSIM” option in your settings is a good sign, but some phones have regional restrictions. If you’re not sure, please contact our support team before you buy.
