Direct answer

What is the best eSIM for Cambodia?

The strongest travel eSIM for Cambodia is whichever brand rides Metfone, Smart or Cellcard with the broadest verified coverage for your route, honest fair use terms, working hotspot, and a clear position on the country's mandatory SIM-registration rule. Unlike much of Europe, Cambodia does compel SIM registration: by law a passport or ID is recorded against every SIM, so a local prepaid SIM is registered at the kiosk, while a travel eSIM usually settles that step inside its own checkout. Coverage is strongest around Phnom Penh, Siem Reap and Sihanoukville and thins across the Cardamom highlands and remote provinces. Weigh the brands in the ranking below.

Local networks

Which local network does each travel eSIM use in Cambodia?

A travel eSIM brand sells the plan; a Cambodian carrier carries the signal. Whichever of the national networks a brand rides is what fixes your real-world coverage, your reach beyond the towns, and whether 5G appears. The grid further down maps each brand to its host carrier in Cambodia.

Cambodia is served by three dominant mobile networks: Metfone, run by the Vietnamese military-owned Viettel group, which carries the widest rural and remote-province footprint and the largest subscriber base; Smart (Smart Axiata), part of Malaysia's Axiata group, known for fast urban 4G across Phnom Penh, Siem Reap and Battambang; and Cellcard, the country's only homegrown operator, launched in 1997 and strong across the main cities and tourist towns. Smaller operators such as Yes and Cootel also exist. All three majors switched on 5G at the start of 2025. Most travel eSIMs sold for Cambodia host on Metfone, Smart or Cellcard.

ID and SIM registration

Does Cambodia require ID to register a SIM? (KYC)

Whether you must show identity papers comes from national law, not from the eSIM brand. Here is the verified position for Cambodia.

Yes, Cambodia requires prepaid SIM registration. Registration is overseen by the Telecommunication Regulator of Cambodia (TRC) under the Law on Telecommunications, promulgated by Royal Decree NS/RKM/1215/017 on 17 December 2015, and tightened by later sub-decrees. Operators and resellers must record valid identity details against every SIM before activation; for a visitor a passport is the accepted document, and the SIM is registered in your name at the point of sale. The TRC has run repeated crackdowns on unregistered and improperly registered SIMs, so an anonymous local prepaid is not an option. With a travel eSIM the picture is simpler, as the brand typically captures any required identity step inside its own online checkout and you rarely register at a counter. Confirm each brand's flow before buying. Sources [4] [5].

Region context

How Cambodia compares to its Southeast Asian neighbours

Cambodia sits on the Indochinese peninsula, bordered by Thailand to the northwest, Laos to the north, and Vietnam to the east, with a Gulf of Thailand coastline to the southwest.

Cambodia is not part of any roam-like-at-home zone, so unlike the EU there is no bloc-wide rule that keeps one local plan alive across the border into Thailand, Vietnam or Laos; a Cambodia-only plan stops at the frontier and a regional or Asia-wide eSIM is the usual way to cross. The country's terrain shapes coverage: a low central plain built around the Mekong river and the Tonle Sap, Southeast Asia's largest lake, carries the densest signal, while the Cardamom Mountains in the southwest and the remote northeastern provinces thin it out. The big draws cluster tightly, the temples of Angkor at Siem Reap, the capital Phnom Penh, and the coast and islands off Sihanoukville, all of which sit inside the well-served zone. On money, Cambodia runs a deeply entrenched dual-currency economy: the official Cambodian riel (KHR) handles small change while the US dollar is used for most larger payments, so eSIM checkouts are commonly priced in USD.

Plans by brand

Travel eSIM plans for Cambodia, by brand

The full grid of every brand and plan offered for Cambodia, with data, validity, price, host network, hotspot, KYC and top-up. Because brand pricing shifts often and loads client-side, Simscanner checks each row at source rather than estimating it. Every cell sits in a pending state until that check is done.

No invented prices. Simscanner will not print a plan price, data amount, validity or fair use cap it has not confirmed at the brand. Each field below holds at pending until a real source backs it.

Cambodia eSIM plans are commonly priced in US dollars (USD $), reflecting the country's dual-currency economy. A plan row goes live only after its brand source is checked. We never make up a price or a data figure.

FAQ

Frequently asked questions about Cambodia eSIMs

Straight answers to what Cambodia-bound travellers ask most. The wording lives in the page itself so both search engines and AI readers can lift it.

Do I need ID or a passport to use an eSIM in Cambodia?

Cambodia requires every SIM to be registered against valid identity details, so a local prepaid SIM is registered in your name at the kiosk using your passport. The rule is enforced by the Telecommunication Regulator of Cambodia. With a travel eSIM the brand usually handles any identity step inside its own online checkout, so you rarely register at a counter. Confirm the brand's process first, and carry your passport.

Which local networks do Cambodia eSIMs use?

Cambodia has three dominant networks: Metfone (Viettel-owned, the widest rural reach and largest subscriber base), Smart (Smart Axiata, fast urban 4G), and Cellcard (the only homegrown operator, launched 1997). Smaller players such as Yes and Cootel also exist. Most travel eSIMs ride Metfone, Smart or Cellcard. The local networks table on this page maps each brand to its Cambodian carrier once that mapping is verified.

Can I use a Cambodia eSIM in Thailand or Vietnam?

Usually not. Cambodia is not in any roam-like-at-home zone, so a Cambodia-only plan generally stops working at the Thai, Vietnamese or Lao border. If your trip crosses several countries, look for a regional Southeast Asia or Asia-wide eSIM rather than a single-country Cambodia plan. Always check each brand's coverage list before you set off.

Is there 5G coverage for eSIMs in Cambodia?

5G depends on the Cambodian network the eSIM rides and whether the plan includes it. Metfone, Smart and Cellcard all switched on 5G at the start of 2025, with the densest coverage around Phnom Penh, Siem Reap and other main cities. Simscanner does not yet publish a verified per-brand 5G figure for Cambodia; the speed section fills in once verified.

How do I activate an eSIM before arriving in Cambodia?

Buy the plan, then install the eSIM over home Wi-Fi by scanning its QR code or using one-tap install. Leave it set to start on first contact with a Cambodian network, switch data roaming on for that line, and make it your data line as you land in Phnom Penh or Siem Reap. Exact prompts differ by brand and device.

What is FUP on a Cambodia eSIM?

FUP is the fair use policy: the threshold past which a brand may slow an unlimited plan. On a Cambodia eSIM this often appears as a daily high-speed allowance before throttling. The plans table on this page lists each brand's allowance and throttle once verified, and never carries an invented limit.
