Airalo, Saily, and Nomad sell fixed data only. A 7-day unlimited plan costs $25.62 total ($3.66/day). Fixed data tiers for comparison: 1GB: $3.99, 3GB: $7.99, 5GB: $11.49.

The choice depends on individual usage patterns for Cambodia.
Data consumption
Cambodia data usage, app by app
Every gigabyte counts on a fixed-data plan. Here is the activity-by-activity breakdown for Cambodia at the current floor rate. Google Maps: 2.1 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: 23 MB per 30 min ($0.03 at $1.44/GB). Zoom: 600 MB per 1 hr ($0.84 at $1.44/GB). Instagram: 25 MB per 10 min ($0.04 at $1.44/GB). TikTok: 67 MB per 10 min ($0.09 at $1.44/GB). WiFi availability in Cambodia is rated good, so offloading Zoom and streaming to hotel WiFi reduces eSIM consumption.
Plan sizing
Cambodia data sizing, trip by trip
HelloRoam leads the 2026 composite at 4.64/5 in our comparison matrix 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
Cambodia roaming charges against eSIM savings
HelloRoam leads the 2026 composite at 4.64/5 in our comparison matrix for Cambodia. US carriers charge $12/day for international roaming in Cambodia. eSIM plans start at a fraction of that cost. Carrier roaming: $12/day x 7 days = $84.00. eSIM entry: $3.99 for 1GB in Cambodia. Savings: $80.01 (95%) over a 7-day trip. Unlimited eSIM: $3.66/day x 7 days = $25.62, which saves $58.38 vs carrier roaming. HelloRoam and Holafly both sell unlimited: HelloRoam from $5, Holafly from $2.99/day. Carrier roaming typically includes data, talk, and text. eSIM plans cover data only. Factor in WiFi calling if you need voice service in Cambodia.
