HelloRoam -- Best Coverage + Value
HelloRoam prices Cambodia from $3.50/GB, above the country's own $1.44/GB floor but below Airalo's general $4.50/GB rate, inside an 8.6/10 composite score 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.
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
- 31+ local currencies supported at checkout
- 63-language interface for non-English travelers
Cons
- Email-only support with 12-24 hour response times
- Newer brand (launched August 2025) with shorter track record
- App store ratings still building compared to Airalo
Airalo -- Best Overall Coverage
Airalo carries the primary-routing assignment for Cambodia and posts this matrix's top coverage score at 4.9/5, backed by a 4.8/5 iOS app rating, the highest of the five providers compared. 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.
Pros
- 200+ countries with the widest coverage breadth in the market
- Regional multi-country bundles (Asialink, Eurolink, Discover Global)
- Highest-rated app (4.8/5 iOS, 4.6/5 Android) 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
- Customer support slower than premium providers (4-6 hour email response)
Holafly -- Best Unlimited Data
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 to 256 Kbps-1 Mbps, a real limit against Cambodia's own $1.44/GB fixed-tier floor for shorter trips.
Pros
- Unlimited daily data from $2.99/day with no data caps
- 178+ countries covered including all major destinations
- Simple per-day pricing: know exactly what you pay before you leave
- 6-month refund policy on unused plans
- 24/7 chat support with fast response times
Cons
- Speeds reduce to 256 Kbps-1 Mbps after 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
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.
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
- 150 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
- 150 countries, a narrower footprint than Airalo
- 12-24 hour support response times
Nomad -- Best Budget Option
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 112-country footprint, the narrowest of the five providers, leaves Airalo carrying the primary assignment here despite Nomad's regional pricing strength.
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 24-48 hour response times
- Basic app compared to Airalo and Saily
- 112 countries, the narrowest footprint among the five providers
- Limited plan variety in some countries
FAQ
Frequently asked questions about eSIMs for Cambodia
Which eSIM provider covers Cambodia as the primary carrier?
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 4.8/5 iOS app rating. HelloRoam, Holafly, Saily, and Nomad all list the country as a secondary option, with HelloRoam's 204+ carrier partnerships extending in at a lower $3.50/GB floor.
How much does eSIM data cost in Cambodia?
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 to 256 Kbps-1 Mbps, 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, documented at a 20 Mbps average download speed. 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 at a 20 Mbps average download speed.
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.
