Methodology
How we score eSIM providers
Five dimensions, each weighted at 20 percent.
Country count, carrier partnerships, regional bundle availability
Per-GB floor, plan tier spread, value at common data amounts
Carrier routing and which network generations that carrier publishes
Installation flow, data tracking, interface quality
Channel availability and refund policy
All scores are editorial assessments based on verified data. Pricing checked weekly. See our full scoring methodology for details.
HelloRoam -- Highest Composite Score
HelloRoam scores 4.64/5 on our rubric overall for Cambodia, with App 5.0 and Support 5.0. Plans price from $3.50/GB, above the country's own $1.44/GB floor but below Airalo's general $4.50/GB rate, built on 186-country reach. Its 204+ carrier partnerships extend into Cambodia alongside Airalo's primary-routing assignment, a comparison point worth pricing against Cambodia's own tiers before checkout.
Dimension scores, 0-5 on our rubric
Pros
- 186 countries with 204+ carrier partnerships for reliable local routing
- Fixed plans from $3.50/GB across popular destinations
- Unlimited plans from $5 for short stays, scaling by duration
- iOS and Android app with in-app top-up, add-destination, and usage alerts
- Live chat, WhatsApp, and email support, including real-time channels
- 31+ local currencies supported at checkout
- 63-language interface for non-English travelers
Cons
- Newer brand (launched August 2025) with shorter track record
- 186 countries, behind Airalo's 200+ catalogue
Airalo -- Widest Coverage Catalogue
Airalo carries the primary-routing assignment for Cambodia and posts this matrix's top coverage score at 4.9/5, backed by a 4.7/5 App score, behind HelloRoam's App 5.0. That breadth costs more than Cambodia's own $1.44/GB floor, with Airalo's general $4.50/GB rate applying once a country-specific plan resets to standard pricing.
Dimension scores, 0-5 on our rubric
Pros
- 200+ countries with the widest coverage breadth in the market
- Regional multi-country bundles (Asialink, Eurolink, Discover Global)
- Automatic in-app install with real-time data tracking and hourly runtime estimates
- Airmoney cashback rewards (5-10% depending on loyalty tier)
- Established brand since 2019 with proven reliability
Cons
- Per-GB pricing higher than budget alternatives
- Unlimited plans available in select markets only, not all 200+ destinations
- No live chat or WhatsApp channel: support runs on email and in-app messaging
Saily -- Best for Privacy
Saily does not carry the primary-routing assignment for Cambodia in this dataset, and its general $3.99/GB rate runs well above the country's own $1.44/GB floor. Its bundled NordVPN remains a real feature on Cambodia's public Wi-Fi, rated good across hotels and cafes in Phnom Penh and Siem Reap, a layer Airalo and HelloRoam do not include by default.
Dimension scores, 0-5 on our rubric
Pros
- Backed by NordVPN parent company Nord Security with proven privacy infrastructure
- Integrated VPN protection included on every plan at no extra cost
- Clean, privacy-focused app with VPN toggle inside the eSIM interface
- 200 countries with strong European coverage
- 30-day refund policy
Cons
- Email-only support with no live chat or WhatsApp for urgent help
- Fixed data plans only; no unlimited daily tier
- 200 countries, just behind Airalo's 200-plus
Holafly -- Best Unlimited Daily Rate
Holafly's unlimited plans start at $3.66 a day for Cambodia, dropping to $3.00 a day on the 30-day tier, an 18% cut that undercuts a fixed 20GB plan for a stay past three weeks. A 2GB daily fair-use threshold applies before speeds reduce sharply, a real limit against Cambodia's own $1.44/GB fixed-tier floor for shorter trips.
Dimension scores, 0-5 on our rubric
Pros
- Unlimited daily data from $2.99/day with no data caps
- 160+ countries covered including all major destinations
- Simple per-day pricing: know exactly what you pay before you leave
- 180-day refund policy on unused plans
- 24/7 chat support alongside email
Cons
- Speeds reduce after the daily fair use threshold on most plans
- Hotspot tethering limited to 1 GB/day on select destinations
- Not cost-effective for light data users (under 3 GB/trip)
- Fewer countries than Airalo
Nomad -- Best Budget Per-GB Rate
Nomad's discounted pricing tier concentrates in Southeast Asia, the same region Cambodia sits in, though this dataset does not list Nomad as the primary-routing provider for the country. Its 200-country footprint, behind only Airalo's 200-plus, leaves Airalo carrying the primary assignment here despite Nomad's regional pricing strength.
Dimension scores, 0-5 on our rubric
Pros
- Competitive pricing starting from $3.00/GB in Southeast Asia
- Simple, fast checkout with no account required in many cases
- Lowest per-GB rates for Thailand, Vietnam, South Korea, and Japan
- Plans start at a low entry price for short trips
Cons
- Email-only support with no live chat, WhatsApp, or phone channel
- Basic app compared to Airalo and Saily
- 200 countries, behind only Airalo among the five providers
- Limited plan variety in some countries

Which eSIM provider covers Cambodia as the primary carrier?
Airalo carries the primary-routing assignment for Cambodia in this dataset, posting the matrix's top coverage score at 4.9/5 and a 4.7/5 App score.

How much does eSIM data cost in Cambodia?
Cambodia's own per-GB floor lands at $1.44 on the 20GB tier, among the cheapest rates in this five-way matrix, rising to $3.99 on the smallest 1GB tier for a short trip. HelloRoam prices the country from $3.50/GB and Airalo from $4.50/GB as general rates, both above Cambodia's own country-specific floor.
Does Cambodia have an unlimited eSIM option?
Does Cambodia have an unlimited eSIM option?
Yes. Holafly's unlimited plans start at $3.66 a day for Cambodia, dropping to $3.00 a day on the 30-day tier, an 18% cut for longer stays. A 2GB daily fair-use threshold applies before speeds reduce sharply, a spec worth weighing against Cambodia's own $1.44/GB fixed-tier floor.
Does Cambodia have 5G eSIM coverage?
Does Cambodia have 5G eSIM coverage?
No. Commercial 5G has not launched in Cambodia, so every provider in this five-way matrix runs on the same 4G LTE ceiling. That fixed spec holds regardless of which e-sim supplies the connection or which of the five brands sells the plan.
Do I need a passport to activate an eSIM in Cambodia?
Do I need a passport to activate an eSIM in Cambodia?
No. Cambodia's passport requirement applies to a local physical SIM bought at a carrier counter, a step every e SIM in this comparison skips by activating before the flight lands. The five providers compared here confirm activation through email or app delivery instead.
Which carrier has the widest coverage in Cambodia?
Which carrier has the widest coverage in Cambodia?
Metfone, a Viettel subsidiary, carries the widest reach among Cambodia's three networks in this dataset, ahead of Cellcard and Smart Axiata. Metfone also carries the assigned data-eSIM connection for the five providers compared here, running on 4G LTE.
Is an eSIM cheaper than a local SIM in Cambodia?
Is an eSIM cheaper than a local SIM in Cambodia?
Close in price. A local SIM at Phnom Penh or Siem Reap airport costs $2 to $5 for 5GB to 20GB over 28 days, similar to Cambodia's own eSIM pricing at $3.99 for 1GB. The difference is the passport check at the counter, a step an e-sim installed before departure skips.
