Touch down in Phnom Penh or Siem Reap, switch off airplane mode, and your Lumbus eSIM connects on its own — no SIM counter, no paperwork at arrivals. The QR code lands in your email the moment you buy, so you can install it at home and walk out of the airport already online, hotel pinned and ride booked.
Compare plans and find the perfect fit for your trip

Your Cambodia eSIM connects to 2 mobile networks, automatically switching to the strongest signal — with speeds up to 4G.
Data does real work in Cambodia. Travelers hail tuk-tuks with PassApp and Grab, follow Google Maps to the Royal Palace in Phnom Penh, and point a translate app at Khmer menus. At Angkor Wat, you'll want signal to share the sunrise and find your driver at the temple gate.
An eSIM for Cambodia keeps it simple: buy before you fly, tap the install link from your email and your phone sets the eSIM up itself — or scan the QR code if you prefer — and skip the store visit entirely. Your home SIM stays in your phone, so you never lose your regular number.
The real networks your Lumbus eSIM connects to in Cambodia.
Your Cambodia eSIM runs on Metfone's 4G network, and there's nothing to configure: once installed with data roaming on, your phone finds the strongest available signal and connects by itself. 4G is the top speed here, and it handles maps, ride hailing, messaging, and photo uploads — from Phnom Penh's riverside to Siem Reap's temple roads.

Practical advice for using mobile data in Cambodia.
Buy your eSIM at home, tap the install link in your email so your phone sets it up on its own — or scan the QR code — and set it as your data line, so you land in Phnom Penh or Siem Reap already connected.
PassApp and Grab both run in Phnom Penh and Siem Reap, with fares shown up front — no haggling outside the Night Market at midnight. You just need data to book.
The Angkor Archaeological Park is enormous, and temples like Banteay Srei and Beng Mealea sit far from town. Save the Siem Reap offline map before you head out.
Khmer script is beautiful but unreadable to most visitors. Download the Khmer pack in Google Translate, then point your camera at menus in Kampot or street signs in Battambang.
The bus between Phnom Penh and Siem Reap is a long ride. Turn on your hotspot so the whole row can stream, message, and map the Tonle Sap.
