Best eSIM for Cambodia in 2026
A real review and setup guide for staying online across Cambodia.
I wound through Cambodia over a couple of weeks, all on one eSIM. Phnom Penh first, up to Siem Reap for the temples around Angkor, a slow detour through Battambang, and a final stretch on the coast at Sihanoukville.
Phnom Penh and Siem Reap ran on solid 4G, and the ride between them held signal the whole way. Cambodia has not switched on commercial 5G yet, so LTE is what everyone gets, and Metfone's LTE was quicker than I expected. It thinned to 3G on some back roads around Battambang and came back near every town.
What I actually used it for
- Booking a Grab from Phnom Penh airport before I'd properly found the exit.
- Offline maps and navigation around the Angkor temples and out to the floating villages on Tonle Sap.
- Translating Khmer menus and signs, and sorting out prices at the markets.
- Tethering the laptop for work in Phnom Penh, and video calls home from the coast in the evenings.

Why travelers carry an eSIM in Cambodia
Skip the SIM registration
Local Cambodian SIMs need passport registration in a shop. Your eSIM activates online, so you skip it.
Runs on the top network
We route through Metfone, Cambodia's largest network, not a budget reseller.
Cheaper than roaming
Daily roaming rates in Cambodia outrun a whole eSIM plan within a day or two.
Keep your home number
Run both lines at once: home SIM for texts and bank logins, Cambodia eSIM for the internet.
Online the moment you land
Book a Grab and open maps at Phnom Penh airport without hunting for WiFi.
Covered at Angkor and the coast
Solid signal around the Angkor temples, Phnom Penh, and the Sihanoukville coast.
Coverage in Phnom Penh, Siem Reap, and beyond
From Phnom Penh outwards, this is what the signal actually looks like on the ground:
- 4G LTEPhnom PenhQuick 4G LTE across the capital
- 4G LTESiem Reap & AngkorStrong across the temple complex
- 4GSihanoukville & the coastBeaches, port, and the ferry piers
- 4G*Battambang · Koh Rong · countrysideSolid in towns, patchy on remote roads and islands
Metfone reaches most of the populated country on 4G LTE; commercial 5G has not launched in Cambodia yet. On remote back roads and the smaller islands, expect the signal to drop for a while, the same as it does for any local SIM.
Before you fly: a ten-minute checklist
A short list worth doing on home WiFi, so nothing is left for the arrivals hall in Phnom Penh:
- Scan the QR code at home and make sure the Cambodia eSIM is visible in your settings before you pack.
- Download offline Google Maps for Phnom Penh, Siem Reap, and the Angkor temple area.
- Install Grab and PassApp, the main ride-hailing apps in Cambodia, so a tuk-tuk or car is one tap away.
- Save your accommodation address and a few Khmer phrases. English is common in tourist areas, less so on the back roads.
- Pack a power bank. Maps and photos on long temple days drain a battery faster than usual.
How to set up your Cambodia eSIM
The whole flow takes about two minutes. Do it on home WiFi before you fly and arrive in Cambodia already connected.
- 1
Buy a Cambodia plan
Match the plan to your trip length. The Cambodia eSIM is delivered to your email and dashboard the moment you pay.
- 2
Scan the QR code at home
Scan the QR code from your dashboard on home WiFi. Your phone adds the Cambodia eSIM in about a minute, ready to switch on when you land.
- 3
Turn on Data Roaming when you land
Land in Phnom Penh or Siem Reap, switch Data Roaming on for the eSIM line, and you are online before you reach the baggage belt. This is the step most people miss.
- 4
Top up any time during your stay
Run low halfway through Cambodia? Buy more data in the app. It lands on the same eSIM with nothing to scan or reinstall.
Remember: after landing in Phnom Penh, flip Data Roaming on for the eSIM line. That is expected behaviour for travel eSIMs, not a hidden charge.
