eSIM plans · AsiaeSIM Plans for Cambodia (2026)
Roaming in Cambodia can cost $110.00 or more for 11GB. Airalo's 20GB plan covers the same data for $28.80, saving you $81.20 over 7 days on Metfone. Light users save with 1GB at $3.99.
Mobile data in Cambodia runs on Cellcard's 4G LTE network. A 7-day trip at moderate usage (1.5GB/day for maps, messaging, and browsing) totals 11GB. If you grab the 20GB plan for $28.80, you get 9GB of headroom beyond your 11GB baseline. Unlimited data runs $3.66/day on Cellcard's 4G LTE network, which eliminates data tracking for heavy users.
Data needs in Cambodia split into three bands. Light travelers (4GB over 7 days) stick to maps and email at 500MB/day. Moderate travelers (11GB total) add social media and ride-hailing at 1.5GB/day. Heavy travelers (21GB total) stream video and run hotspots at 3GB/day. 1 carrier and 6 4G LTE plans service all three segments.
Each traveler type maps to a specific plan in Cambodia. Light users: the 5GB plan at $11.49 covers the trip without paying for unused data. The 5GB plan at $11.49 gives moderate users the lowest per-GB rate at $2.30/GB for a 7-day trip. Heavy users who burn 3GB+ daily pick unlimited at $3.66/day on Cellcard instead of risking a data cap mid-trip.

Who you're connecting to
In Cambodia, the underlying carrier matters more than the brand on your plan.
If you plan to stream or video call in Cambodia, then the carrier behind your eSIM matters more than the plan label. Metfone handles heavy streaming with consistent 4G LTE speeds across Cambodia's urban and suburban zones. Airalo routes through Metfone, making it the top pick for travelers who need reliable coverage city to city. Holafly routes through Metfone for unlimited plans at $3.66/day, best matched to heavy users on video calls. If you work from cafes or airports in Cambodia, Saily's VPN layer on Metfone encrypts your traffic without a separate app. At $3.99 for 1GB, Nomad's 4G LTE plan targets light users in Cambodia who keep daily usage under 500MB. The bottom line: 1 carrier in Cambodia all offer 4G LTE. Choose by data size first, carrier second.

Pricing notes for Cambodia
If you compare per-GB rates across Cambodia plans, bigger tiers win on unit cost: 1GB at $3.99 ($3.99/GB), 3GB at $7.99 ($2.66/GB), 5GB at $11.49 ($2.30/GB), 10GB at $18.90 ($1.89/GB), 20GB at $28.80 ($1.44/GB).

Common Cambodia eSIM questions
Direct answers grounded in real plan data and carrier coverage.
What plan do I need?
The eSIM plan you need for Cambodia depends on how you use data. A light user (maps and messaging) needs about 1GB, covered by Airalo's 1GB plan at $3.99. A moderate user (social media and navigation) needs 3GB at $7.99. A heavy user (streaming and video calls) needs 25GB at $28.80. All plans run on Cellcard in Cambodia.
How much data do I need?
For a 7-day trip to Cambodia, your data needs depend on activity. Maps and messaging use about 0.09GB/day (1GB total). Social media and navigation use 0.4GB/day (3GB total). Streaming and video calls use 3.53GB/day (25GB total). Cambodia has decent WiFi in hotels and cafes, which offsets about 15% of your data needs. Plans on Cellcard start at $3.99.
Which provider is cheapest?
Airalo offers the lowest eSIM prices for Cambodia. The 1GB plan costs $3.99 ($3.99/GB). Larger plans drop the rate further: 20GB costs $28.80 ($1.44/GB). All plans connect to Cellcard.
Is an eSIM worth it?
An eSIM is worth it for Cambodia. Carrier roaming costs about $110.00 for 11GB over 7 days. Airalo's 20GB plan costs $28.80 on Cellcard, saving you $81.20. No airport SIM queue (typically 15-30 minutes), no contract, and instant activation.

Your questions, answered
How much data do I need for a 7-day trip to Cambodia?
Match your 7-day Cambodia trip to the right size before you buy. Light-touch travelers (maps, texts, quick checks) burn through 4GB. Standard travelers mixing social media, navigation, and web browsing use 11GB. The 20GB plan at $28.80 covers that comfortably on Metfone's 4G LTE network. Add 20% headroom to avoid running out on day 7.
Should I get a fixed data plan or unlimited for Cambodia?
Fixed data beats unlimited for most Cambodia trips. The 20GB plan at $28.80 ($1.44/ GB) covers 7 days of moderate use. Unlimited daily data costs $3.66/day. It only saves money if you use more than 2.5GB per day. For a 7-day trip, unlimited ($23.57) beats the comparable fixed plan ($28.80) when you use more than 2.5GB per day. Choose unlimited if you stream video daily or work remotely; choose fixed for maps, messaging, and casual browsing.
Which eSIM plan fits a light or heavy data user in Cambodia?
If you only check maps and send messages in Cambodia, 4GB covers 7 days. The 1GB plan at $3.99 handles that at $3.99/GB. If you scroll social media and browse regularly, step up to the 5GB plan at $11.49 ($2.30/GB). If you stream video or work on video calls, you need 21GB: the 20GB plan at $28.80 ($1.44/GB) gives you the lowest per-GB rate.
Does my phone support eSIM for Cambodia?
Before booking your Cambodia eSIM, confirm your phone is compatible. Dial *#06# and check for an EID number below the IMEI. That EID means eSIM is supported. iPhones from XS (2018) onward, Samsung Galaxy from S20 onward, and Google Pixel from 3 onward all qualify. Your phone must also be carrier-unlocked to connect to Cambodia's 4G LTE network.
When does my Cambodia eSIM start counting down?
If you install the eSIM QR code at home over WiFi, the clock does not start. The validity window begins only when your phone first connects to Cambodia's network. If you buy too far in advance, the plan may expire before your trip ends. Buy 1–3 days before departure. Short trips fit the 1GB plan at $3.99. Longer stays need the 20GB plan at $28.80.
Is Cambodia well-covered by travel eSIM networks in Asia?
If you stay in Cambodia's cities and tourist areas, 4G LTE coverage is solid on Metfone. If you travel to rural areas, coverage may be less consistent. Travel eSIMs connect to these same domestic carriers. The 5GB plan at $11.49 ($2.30/GB) handles a standard Asia trip.
Which activities use the most mobile data in Cambodia?
Data appetites vary by traveler type in Cambodia. The photo-sharer (Instagram, TikTok, social updates): 300–500MB/day. The navigator (Google Maps, Waze, transit apps): 200–400MB/day. The streamer (YouTube, Netflix, music): 700MB/hour minimum. The remote worker (Zoom, Slack, email): 450MB/hour for video calls. Most tourists combining the first two profiles use 1–1.5GB/day on Metfone's 4G LTE network. The 5GB plan at $11.49 fits 4–7 days of that profile.
Which Cambodia eSIM plan fits my trip length?
If you use 1.5GB/day in Cambodia, match your trip length to a plan: 2–2 days → 3GB at $7.99 ($2.66/GB); 3–3 days → 5GB at $11.49 ($2.30/GB); 5–6 days → 10GB at $18.90 ($1.89/GB); 8–13 days → 20GB at $28.80 ($1.44/GB). If you stream video, add 20% to your estimate before buying. The largest plan always delivers the lowest per-GB rate at $1.44/GB.
When does unlimited data save money in Cambodia?
Unlimited daily data for Cambodia starts at $3.66/day (2GB at full 4G LTE speed before throttling). The minimum commitment is 1 days at $3.51 total. Committing to 30 days drops the daily rate to $3.00 (18% off the base rate). Heavy users streaming video or video-calling save money; light users checking maps and messages pay less with a fixed plan.
What is the best-value Cambodia eSIM plan?
If your Cambodia trip runs 7 days or more, the 20GB plan at $28.80 ($1.44/GB) gives you the best per-GB rate. If your stay is under 4 days, the 1GB plan at $3.99 ($3.99/GB) avoids wasted data. Always buy one tier above your estimate so you do not run out mid-trip.
