Data consumption
App-by-app data usage in Cambodia
Every gigabyte counts on a fixed-data plan. Here is the activity-by-activity breakdown for Cambodia at the current floor rate. Google Maps: 5 MB per 10 min (under $0.01 at $1.44/GB). Email: 3 MB per 1 email (under $0.01 at $1.44/GB). Spotify: 45 MB per 30 min ($0.06 at $1.44/GB). Zoom: 1024 MB per 1 hr ($1.44 at $1.44/GB). Instagram: 50 MB per 10 min ($0.07 at $1.44/GB). TikTok: 80 MB per 10 min ($0.11 at $1.44/GB). WiFi availability in Cambodia is rated good, so offloading Zoom and streaming to hotel WiFi reduces eSIM consumption.
Plan sizing
How much data do you need for Cambodia?
Choosing the right plan tier for Cambodia depends on trip length and daily data habits. A 7-day trip at 0.8 GB/day = 5.6 GB raw. Cambodia's good WiFi reduces eSIM load by ~25%, bringing the adjusted need to 5 GB. The 5GB tier at $11.49 ($2.30/GB) covers that. For heavy video or hotspot use, step up to the next tier to avoid mid-trip top-ups.
Savings
Roaming charges vs eSIM savings in Cambodia
US carriers charge $10/day for international roaming in Cambodia. eSIM plans start at a fraction of that cost. Carrier roaming: $10/day x 7 days = $70.00. eSIM entry: $3.99 for 1GB in Cambodia. Savings: $66.01 (94%) over a 7-day trip. Unlimited eSIM: $3.66/day x 7 days = $25.62 — saves $44.38 vs carrier roaming.

FAQ
Common questions about eSIMs in Cambodia
How do you score eSIM providers for Cambodia?
We score each provider on five weighted dimensions for Cambodia: Pricing (25%) — per-GB cost and plan range; Coverage (25%) — carrier routing quality and 4G LTE network reach via Metfone; Speed (20%) — measured download speeds on the local network; App quality (15%) — installation flow, eSIM management, and support response time; Support (15%) — refund policy length and issue resolution speed. Airalo, Holafly, Saily, and Nomad are scored independently for each destination. The same provider can rank differently for Cambodia versus other countries depending on local carrier partnerships and pricing.
Which provider has the highest coverage score in Cambodia?
Airalo leads on coverage breadth for Cambodia with a 5.0/5 coverage score and 200+ country network footprint. Coverage routes through Metfone. For Cambodia specifically, all four providers access the same 4G LTE infrastructure, so urban coverage is comparable between them. Airalo's coverage advantage matters most for multi-country itineraries extending beyond Cambodia — Holafly, Saily, and Nomad score equally for single-country trips.
What criteria does the comparison matrix use for Cambodia?
Five scoring dimensions drive the Cambodia matrix. Pricing (25%) compares per-GB cost at each tier — the lowest rate for Cambodia is $1.44/GB. Coverage (25%) measures carrier routing breadth: all four providers access 4G LTE via local operators. Speed (20%) reflects measured download averages, not theoretical peaks. App quality (15%) grades installation flow and data management features. Support (15%) weighs refund windows: Holafly's 6 months leads, Airalo's 14 days trails. Each dimension is scored 1-5, then weighted to produce the composite ranking.
How much data do I need for Cambodia?
Most travelers to Cambodia use 1-2GB per day on cellular. Maps, messaging, and social media consume 500MB-1GB daily. Streaming video pushes usage to 3-5GB per day. For a 7-day trip with good WiFi availability, a 5GB fixed plan covers light-to-moderate usage comfortably. Heavy users should consider Holafly's unlimited daily plan at $3.66/day. WiFi at hotels and cafes in Cambodia reduces cellular consumption by 30-60% depending on usage patterns.
Is unlimited data worth the cost in Cambodia?
Unlimited data in Cambodia costs $3.66/day through Holafly — $25.62 for a 7-day trip. A 5GB fixed plan costs $11.49. The breakeven point: if you use more than 8GB during your Cambodia trip, unlimited becomes cheaper per-GB. Remote workers streaming video or on daily video calls easily exceed 5GB per day, making unlimited the clear value play. Casual travelers using maps and messaging rarely need unlimited.
When should I activate my eSIM for Cambodia?
Install your Cambodia eSIM 24-48 hours before departure while you have stable WiFi. Do not enable data roaming until you land. Most providers start the plan validity clock at first data use, not at installation. Airalo and Holafly both confirm this policy for Cambodia. Saily and Nomad start validity on first connection. Install early to troubleshoot any QR scanning issues while you still have home internet. Enable data roaming in Cambodia only after landing and clearing customs.
How do I set up dual SIM for Cambodia?
Set your travel eSIM as the data line and keep your home SIM for calls and texts. On iPhone: Settings > Cellular > select the Cambodia eSIM line > Turn On This Line > set as Cellular Data. On Android: Settings > Network > SIM Manager > set eSIM as mobile data. Disable Data Roaming on your home SIM to prevent charges. Enable Data Roaming on the Cambodia eSIM only. All four providers — Airalo, Holafly, Saily, Nomad — work in dual SIM mode.
What speeds can I expect from a travel eSIM in Cambodia?
Cambodia travel eSIMs run on 4G LTE. Average measured download speed is 20 Mbps. All four providers — Airalo, Holafly, Saily, Nomad — access the same Metfone infrastructure, so the speed difference between providers is minimal under normal conditions. Peak-hour slowdowns affect all providers equally in dense urban areas. The speed column in our comparison matrix reflects measured averages, not carrier specifications.
Do all providers have the same speed in Cambodia?
All four providers deliver nearly identical speeds in Cambodia — 20 Mbps average — because they route through the same Metfone infrastructure. eSIM providers do not own towers; they lease capacity from Cambodia's carriers. Speed differences between Airalo, Holafly, Saily, and Nomad are negligible under normal conditions. Peak-hour congestion in Cambodia cities affects all providers equally. Our Speed dimension (20% weight) scores them within 0.2 points of each other for most destinations.
How do I choose the right eSIM provider for Cambodia?
For Cambodia, the four providers split into clear use cases. Airalo scores highest for multi-country itineraries — 200+ destinations on a single account. Holafly scores highest on unlimited daily data if you stream or work remotely. Saily scores highest on privacy with built-in VPN protection (NordVPN infrastructure) at no extra cost. Nomad has the lowest per-GB price if cost is the deciding factor, starting from $3.99 for 1GB. Fixed data plans suit trips under 14 days; unlimited daily makes sense when you burn 5+ GB per day.
Can I add more data mid-trip in Cambodia?
Airalo supports in-app top-ups for Cambodia — purchase additional data without installing a new eSIM. Holafly's unlimited plan eliminates top-up need entirely. Saily requires a new eSIM purchase for more data. Nomad also requires a separate purchase. Top-ups need an internet connection: WiFi (good availability in Cambodia) or remaining cellular data. Buy top-ups before your current plan runs out to avoid being offline in Cambodia while trying to purchase more data.
What are the refund policies for eSIM providers covering Cambodia?
Refund policies differ across the four providers for Cambodia plans. Holafly offers the most generous policy: 6 months to request a refund on unused plans. Saily and Nomad both offer 30-day refund windows for unused eSIM profiles. Airalo provides a 14-day refund period. All four require the plan to be unused — no data consumed — to qualify. If you have already activated and used data in Cambodia, refunds are at provider discretion.
Can I switch providers mid-trip in Cambodia?
Switching eSIM providers mid-trip in Cambodia requires WiFi and 5-10 minutes. Steps: connect to WiFi, purchase a new plan from the alternate provider, scan the QR code, set the new eSIM as your data line. iPhone 13+ holds multiple eSIM profiles — no deletion needed. Older devices may require removing the old profile first. Refund the unused plan: Holafly gives 6 months, Saily and Nomad 30 days, Airalo 14 days. All four providers connect to the same Cambodia 4G LTE carriers.
How much does an eSIM for Cambodia cost?
Cambodia eSIM prices range from $3.99 for 1GB (entry level) to $28.80 for 20GB (largest fixed plan). Unlimited daily data is available from $3.66/day. The lowest per-GB rate is $1.44 on the highest-volume fixed tier.
