Best eSIM for Cambodia
Angkor, the coast and a lot of road in between. Metfone is the network that covers all three, and Cambodia is one of the few countries where the local SIM is so cheap it deserves a real look.
The picks for Cambodia network breadth wins
Airalo
All three networks, sensible price $21.00 10GB / 30 days, Connect Cambodia- Permitted on Cellcard, Smart Axiata and Metfone, every network that matters here
- Sizes for a short temple trip: $4 for 1GB, $9 for 3GB
- Unlimited option with a published 3GB per day cap
Watch out: Cambodia is not cheap on any travel eSIM, and this is more than double the same data in Thailand next door.

Best record, middle price $23.99 10GB / 30 days- Trustpilot 4.7 across 30,000 reviews, the best of any provider here
- Clean ladder from $5.99 for 1GB to $23.99 for 10GB
- Refunds that actually process, which matters in a country where coverage is uneven
Watch out: Saily publishes no Cambodian network list, so you cannot check whether you will land on Metfone or on something thinner.

- Runs on Cellcard and Metfone
- Sensible for a two-day Angkor stop where you need maps and nothing else
Watch out: It scales badly: $36.01 for 10GB is the second-worst price on the page, and Trustpilot suspended its score during a fake-review cleanup.

Metfone, Smart and Cellcard who reaches where
Metfone, the Viettel network, has the widest rural footprint: the road to Siem Reap, the temple complex itself, the Cardamoms and the coastal provinces. Smart Axiata is strong in Phnom Penh, Siem Reap and Sihanoukville and is usually the fastest in the cities. Cellcard is the local incumbent, solid in the urban areas and thinner on the back roads.
Angkor Wat is better covered than people expect, but the outlying temples, Beng Mealea and Koh Ker, are where a Metfone-capable plan earns its money.

Permissions from each provider's published Cambodia coverage record, 2026-08-31. "Metfone (Viettel)" appears under both names in provider data; it is one network.
Our pick for Cambodia is Airalo on Cellcard and Smart Axiata and Metfone (Viettel), 10GB for $21 over 30 days.

GigSky's unlimited is the one part of its Cambodia catalogue that is priced normally, at $14.99 for 3 days. For a short heavy-use trip it is worth a look even though its fixed plans are not.
The largest cap you can read before buying in Cambodia is GigSky's 3.5GB a day, from $14.99 for 3 days.
See GigSky unlimited How every cap comparesThe local SIM is genuinely cheap here an honest comparison
Cambodia sells some of the cheapest mobile data in the world, and it sells it to tourists without much ceremony.
Smart, Cellcard and Metfone all run counters at Phnom Penh and Siem Reap airports, and tourist packs typically run $5 to $12 for large data allowances over a week or a month, with a Cambodian number included. Registration takes your passport at the counter.
Against that, a 10GB travel eSIM is $21. The gap is not a rounding error, it is three to four times the price.
What the eSIM buys you: landing connected at an airport where the counter may be closed for a late flight, no passport photocopy, and a plan that already works when you cross from Thailand or Vietnam. For a week or less, or as one leg of a longer Southeast Asia trip, that is a fair trade. For a month in Cambodia, buy locally.
Cambodia questions the ones people actually search
Which eSIM is best for Cambodia?
Airalo Connect Cambodia at $21 for 10GB, because it can use Cellcard, Smart and Metfone, and Metfone is what reaches the outlying temples and the coast. Saily at $23.99 for the better support record. Avoid GigSky here at $54.99. Checked August 2026.
Is there mobile signal at Angkor Wat?
Yes, at the main temples and along the circuit roads, on all three networks. The outlying sites like Beng Mealea and Koh Ker are where coverage thins and a Metfone-capable plan is worth having. Download the offline map for the whole park before you go.
Is a Cambodian SIM cheaper than an eSIM?
Yes, by a lot: tourist packs from Smart, Cellcard or Metfone typically run $5 to $12 with generous data, against $21 for a 10GB eSIM. The eSIM buys you arriving connected and no passport paperwork. For a month-long stay, buy locally.
Can I use one eSIM for Thailand and Cambodia?
Yes, with a regional plan: every regional Asia plan in our comparison covers both. Two local packs are still cheaper if your itinerary is settled, and a regional plan is worth the premium if it is not. The comparison is here.
How much data do I need for a week in Cambodia?
Around 3 to 5GB for maps, messaging, ride-hailing and photos. Guesthouse and cafe wifi is widespread and reasonably fast in the cities, less so on the islands and in the countryside.
