Plans are ranked by a combination of real traveler usage, pricing, data value, and coverage reliability. Rankings update automatically as providers change their offerings.
Cambodia's mobile network is served by several local carriers, with Smart Axiata and Cellcard offering the strongest nationwide coverage. 4G is well established in Phnom Penh, Siem Reap and Sihanoukville, while rural areas and jungle routes can revert to 3G or 2G. Travel eSIM providers typically connect to Smart's network, which covers the main tourist circuits reliably. 5G is in very early stages — not yet relevant for most travellers. Cambodia remains one of Southeast Asia's most affordable destinations for mobile data, and international eSIM plans start from under $6 for a short trip.
A travel eSIM is the fastest way to get connected — no SIM shop, no roaming charges, and your home number stays active.

Best eSIM for Cambodia by Traveler Type
Not sure which plan to pick? Here's what we recommend based on your travel style:
Angkor Wat and temple circuit (Siem Reap)
Siem Reap town and the main Angkor temple complex both have solid 4G coverage. Navigation is helpful for cycling or tuktuk rides between temples. A 3 to 5 GB plan for 7 days is plenty for a typical temple-focused trip.
Phnom Penh city stay
Phnom Penh has excellent 4G throughout — riverside, BKK1, Russian Market and Toul Sleng all well covered. Uber-style apps (PassApp, inDrive) require mobile data. A 3 GB plan for 5 days is sufficient for a city visit.
Sihanoukville and coast
Sihanoukville has reasonable 4G coverage on the main beach strips. The outer islands (Koh Rong, Koh Rong Sanloem) have very limited signal — consider downloading entertainment offline. A 5 GB plan for 10 days covers most coastal itineraries.
Kampot, Kep and rural south
Kampot town has reliable 4G. Kep and surrounding countryside are patchier. For eco-lodge stays or nature areas, signal can be sporadic. A 3 to 5 GB plan for 7 days suits a slower-paced southern Cambodia trip.
Multi-country Southeast Asia trip
If combining Cambodia with Vietnam, Thailand or Laos, consider a regional Southeast Asia eSIM from Airalo or Saily that covers multiple countries — simplifies management and can be more cost-effective than separate country plans.
Mobile Networks & 4G/5G Coverage in Cambodia
Cambodia has 3 major mobile operators: Smart Axiata, Cellcard, Metfone. All offer nationwide 4G coverage, with 5G now available in major cities.
4G coverage is strong in Phnom Penh, Siem Reap, Sihanoukville and Kampot. Rural provinces and trekking areas in Cardamom Mountains or Mondulkiri have patchy coverage — often 3G or limited signal. Angkor Wat and the main temple complex have decent 4G signal. Smart Axiata generally delivers the best coverage for travel eSIM users across the country.
Most travel eSIM providers use Smart Axiata or Cellcard infrastructure in Cambodia — both consistently ranked among the best networks in the region. You'll get strong, reliable signal in all major tourist areas.
Tips for Using Your eSIM in Cambodia
🛺 Getting around Cambodia
Cambodia's main ride-hailing options require mobile data — PassApp and inDrive are the most used in Phnom Penh and larger towns.
- PassApp is Cambodia's homegrown ride-hailing app — works well in Phnom Penh
- inDrive is increasingly popular and often cheaper for longer trips
- Tuktuk drivers in Siem Reap often negotiate via WhatsApp — have your number ready
🌐 Internet access in Cambodia
Cambodia has open internet — all major apps, Google, social media and streaming services are freely accessible. No VPN required for standard tourist use.
- Facebook is extremely widely used in Cambodia — many businesses communicate via FB Messenger
- WhatsApp and Telegram both work without restriction
- Google Maps is reliable in cities; Maps.me is a good offline alternative for rural areas
💵 Cash and payments
Cambodia's economy runs largely on US dollars — USD is accepted almost everywhere. The Cambodian Riel (KHR) is used for small change.
- ATMs dispense USD widely — ABA Bank and Canadia Bank are the most reliable
- Card payments are accepted at hotels and tourist restaurants; local markets are cash only
- Carry small USD bills — $1 and $5 notes are essential for tuktuks and street food
🗺️ Coverage in Angkor temple complex
The main Angkor Wat, Bayon and Ta Prohm temples all have reasonable 4G signal. More remote temples in the outer circuit can be patchier.
- Download offline Google Maps of the Angkor complex before your first morning visit
- Preah Vihear and other remote temple sites have very limited signal
- Smart Axiata generally delivers the most consistent coverage across the temple circuit
🏝️ Island coverage (Koh Rong, Koh Rong Sanloem)
The main islands off Sihanoukville have very limited mobile coverage — primarily Wi-Fi at guesthouses.
- Download music, maps and any needed content before taking the ferry to Koh Rong
- Koh Rong Sanloem (quieter island) has almost no mobile signal in most bungalow areas
- Some upmarket resorts have satellite internet — check with your accommodation

How much data do I need for Cambodia?
For a 2-week trip covering Phnom Penh, Siem Reap and Sihanoukville: 5 to 10 GB covers standard use — maps, social media, ride-hailing apps and light streaming. If you're staying on the islands, download entertainment offline and reduce your plan size.

What is an eSIM?
An eSIM (embedded SIM) is a digital SIM card built directly into your smartphone. Instead of inserting a physical plastic card, you install a travel plan by scanning a QR code — in under 5 minutes.
Can I use an eSIM and my regular SIM at the same time?
Yes — your phone uses the eSIM for data while your physical home SIM remains active for incoming calls and SMS.
