Internet in Cambodia: everything you need to know
Cambodia has roughly 70% internet penetration and over 90% 4G mobile coverage (source: ITU DataHub, 2024). 5G is rolling out in Phnom Penh by Smart Axiata. Smart, Cellcard and Metfone (a Viettel subsidiary) share the market.
- ●4G coverage in all major cities (Phnom Penh, Siem Reap, Battambang, Sihanoukville, Kampot) and along main highways. Decent on the Angkor site (Smart has the best footprint around the temples). Patchier in the Cardamoms, Mondulkiri (Sen Monorom OK, jungle weak) and some islands (Koh Rong, Koh Rong Sanloem : resort Wi-Fi more than mobile).
- ●Average mobile speed ~30–50 Mbps download per Ookla (Q1 2025).
- ●No Western services blocked : Google, WhatsApp, Instagram, X, YouTube, Netflix work normally. Telegram and WhatsApp are dominant for hotel / tuk-tuk contacts.
- ●Great for PassApp / Grab (tuk-tuks and taxis), Google Maps, Foodpanda, ABA Mobile and Wing (widely used local mobile money).

Cambodia runs three seasons rather than two: cool and dry from November to February, dry and punishing from March to May, then the monsoon. Only the first lets you set the pace at Angkor instead of the heat setting it for you.
Two currencies, one price
The US dollar circulates alongside the riel and ATMs dispense both; small change comes back in riel. Carry clean, untorn notes, since damaged dollars are routinely refused.
Overland is slower than the map suggests
Phnom Penh to Siem Reap is six hours by road for 320 km, and the southern coast adds another five. Night buses exist but a short domestic flight often buys back a whole day.
The lake that reverses
During the monsoon the Mekong pushes the Tonlé Sap river backwards and the lake grows fourfold. August to October is when the floating villages are genuinely afloat and the flooded forests are navigable.
Buy the Angkor pass separately
Passes are sold at the official ticket centre, not at the temples, in one, three or seven-day versions. One day covers the headline three; three days is what makes the site legible.
Iconic sites and coverage
Angkor Wat
The largest religious monument in the world, built in the twelfth century for Vishnu, later Buddhist, and still on the national flag. Well covered, and while everyone crowds the northern reflecting pool at sunrise, the southern one is nearly empty.
Ta Prohm
The temple left under its silk-cotton and strangler figs, whose roots hold the stones up and prise them apart at once. Patchy signal under the canopy, and a queue at the most photographed tree.
Bayon
216 stone faces across 54 towers, at the exact centre of old Angkor Thom. Signal struggles between the galleries, so agree a meeting point before going in.
Tonle Sap Floating Villages
Houses, schools and markets built entirely on water, whose level shifts by eight metres across the year. Little to no signal offshore; pick a community-run operator over a cut-price tour.
Koh Rong
The largest Cambodian island in the Gulf of Thailand, with bioluminescent plankton on some beaches and bungalows without continuous power. Weak signal, so tell people you will be out of reach.
Royal Palace, Phnom Penh
The royal residence since 1866, with the Silver Pagoda and its floor of 5,000 solid silver tiles. Well covered, modest dress required, and closed over lunch.
Tuol Sleng Genocide Museum
The school the Khmer Rouge turned into S-21 prison, now a memorial. The audio tour runs two hours and needs time afterwards: do not schedule it before a flight.
Kampot Pepper Farms
A protected-origin pepper grown on quartz soils below the Cardamom hills, with farms open to visitors. Signal is unreliable on the tracks between plantations.

Price per GB in Cambodia: what our data shows
According to the Datadopt Observatory, the lowest price per GB recorded in Cambodia comes down to 0.15 €/GB, across a sample of 1,787 fixed-volume offers retained for the measurement. That floor is reached on large data bundles : a 5 GB plan over 30 days costs noticeably more per GB. The real differentiator is still the depth of the offer : the more plans compete, the easier it is to find the duration and data volume that fit your trip.

Frequently asked questions
Does the eSIM really work in Cambodia?
Yes. International eSIMs connect to Smart, Cellcard or Metfone on landing at Phnom Penh (PNH), Siem Reap-Angkor (SAI) or Sihanoukville (KOS).
How much data for 10 days in Cambodia?
For Phnom Penh + Siem Reap (Angkor) + coast, plan 5–8 GB : Maps, PassApp/Grab, cloud photos, WhatsApp/Telegram, some streaming. More if you do lots of video calls.
Is there signal around the Angkor temples?
Yes on the main circuit temples (Angkor Wat, Bayon, Ta Prohm) with Smart Axiata. For remote temples (Beng Mealea, Banteay Srei, Koh Ker), expect weak signal : download offline Maps and the digital Angkor pass before entering.
Can I use my European plan in Cambodia?
Non-EU roaming is charged at premium rates (up to €10/MB). Check ; otherwise a travel eSIM is much cheaper.
Can I share the connection with other devices?
Most Cambodia eSIM plans allow hotspot : the field is listed on each Datadopt offer detail page.
