Best eSIM for Cambodia: Real Prices Compared for Siem Reap, Phnom Penh and Beyond

Angkor Wat alone pulls millions of visitors to Cambodia every year, and between temple-hopping in Siem Reap, the riverside energy of Phnom Penh, and the beaches around Sihanoukville, most trips cover more ground than a single city break — which makes a reliable data plan more useful here than almost anywhere else on a typical Southeast Asia itinerary. We checked live pricing across 120 providers we track for Cambodia, so here's what the actual pricing looks like today.

Quick-answer picks

• Cheapest way to get connected: Yesim's 200MB / 1-day plan at $0.50 — a genuinely tiny allowance, more of a "just enough for maps and messaging" option than a real day of use.
• Best value for a week around Siem Reap or Phnom Penh: Signalinks' 5GB / 7-day plan at $6.50 — comfortable for temple photos, navigation, and staying in touch without rationing data.
• Best for two to three weeks touring the country: BNESIM's 10GB / 30-day plan at $6.55 — an unusually strong price for a month's worth of data, more than enough for most multi-stop itineraries.
• Best raw price per GB: BNESIM's 100GB / 30-day plan at $40.33, working out to roughly $0.42 per GB — the best deal by far if you need serious data volume (hotspotting, video calls, heavy uploads) rather than a light travel allowance.
• Best unlimited option: Superalink's Unlimited / 1-day plan at $0.79 — the cheapest genuinely unlimited rate we found, priced per day rather than as a flat weekly bundle.

Provider-by-provider breakdown

Yesim has the lowest headline price in our Cambodia catalog, but at 200MB it's genuinely a minimal, backup-style allowance rather than a plan you'd rely on for a real day of navigation and photo-sharing — useful as a cheap way to confirm your eSIM setup works before committing to a bigger plan.

Signalinks is the strongest all-round pick for a standard one-to-two-week trip: $6.50 for 5GB/7 days, with a 5-day variant at $5.90 if your trip doesn't line up neatly with a week. If you're touring both Siem Reap and Phnom Penh on one trip, this is a sensible default.

BNESIM dominates the higher end of the market — their 10GB/30-day plan at $6.55 undercuts most other providers' month-long options by a wide margin, and their 100GB/30-day plan at $40.33 is the best price-per-GB in the entire catalog. For any trip longer than two weeks, or any traveler who wants a genuinely large buffer, BNESIM is worth checking first. They also currently run a discount code worth applying before checkout:

Superalink offers the cheapest real unlimited rate at $0.79/day — useful for heavy streaming or video calls, though remember to multiply by your actual number of travel days before comparing it against a fixed-data weekly bundle.

Yatelo is a solid budget-weekly pick at $1.75 for 1GB/7 days — genuinely useful if you're mostly relying on hotel or café wifi and just need occasional mobile coverage rather than a full data plan.

co:sim and eSIMGlobe round out the lower-data tier — co:sim now prices its entry option as a genuine Unlimited/1-day pass rather than a small fixed allowance, and eSIMGlobe's cheapest is a 500MB/1-day plan at currently unavailable — both reasonable fallback options if your first-choice provider's network doesn't work well in a specific part of the country.

NXTL prices Cambodia as a metered pay-as-you-go rate (around $1.97 per GB used) rather than a fixed day or weekly bundle — worth knowing if you'd rather pay only for what you actually use instead of committing to an allowance upfront.

Ubigi offers a 0.5GB/1-day plan at $2.00 — pricier than most of the alternatives above for a similar allowance, worth comparing directly against Yesim or co:sim before choosing it specifically.

Why prices vary this much

Plans here are solving completely different problems even though they're all "Cambodia eSIM":

• Minimal top-up tiers vs. real trip-length plans. Yesim's 200MB tier is built for occasional, light use — checking messages and maps between long stretches of wifi — not a full day of active navigation and photo uploads. Signalinks' 5GB weekly tier is the real "normal traveler" plan by comparison.
• BNESIM's bulk-data pricing model. BNESIM's strength across both the 10GB and 100GB tiers comes from pricing large data volumes efficiently rather than optimizing the smallest entry tier — which is exactly why it wins on price-per-GB but isn't necessarily the cheapest single-day option.
• Day-rate unlimited vs. fixed bundles. Superalink's per-day unlimited plan is genuinely competitive for trips under about three days, but a fixed-data plan like Signalinks' usually wins out for anything longer once you do the multiplication.

Which plan fits your trip

• A few days in Siem Reap for Angkor Wat: Signalinks' 5GB/5-day plan at $5.90 keeps you covered for temple navigation and photos without paying for unused days.
• A full week across Siem Reap and Phnom Penh: Signalinks' 5GB/7-day plan at $6.50 is the clear standard pick.
• Two to three weeks touring the country, including Sihanoukville: BNESIM's 10GB/30-day plan at $6.55 comfortably covers a longer, multi-stop itinerary.
• Digital nomad or extended stay with heavy data use: BNESIM's 100GB/30-day plan at $40.33, or Superalink's unlimited day-rate at $0.79/day if you'd rather not commit to a large fixed bundle upfront.

A few practical notes

Cambodia isn't always included in broader Southeast Asia regional bundles at the same rate as neighboring Thailand or Vietnam, so if you're combining Cambodia with other countries on one trip, check a plan's coverage list carefully rather than assuming it's automatically included — our multi-country trip planner can show you real plans that genuinely cover Cambodia alongside your other destinations. Network coverage is generally solid in Siem Reap, Phnom Penh, and Sihanoukville; more rural areas and some border regions can be noticeably weaker regardless of provider.

All prices above come straight from each provider's real, current pricing, checked daily rather than published once and left stale. If this is your first time using an eSIM, our beginner's guide to how eSIMs work covers installation and activation from the very start.
