For Singaporeans heading to Cambodia — whether it’s Angkor Wat in Siem Reap or street food in Phnom Penh — staying connected is key. But roaming fees can be steep, and local SIMs often require passport registration or a trip to a shop. With the best eSIM for Cambodia, you get instant mobile data upon landing, with high-speed 4G/5G data on your iPhone, Samsung, and many more devices.

Stay effortlessly connected as you travel through Cambodia. Let’s dive in!

For the beginner: What is eSIM?

eSIM is an embedded SIM, which can replace the traditional physical SIM card in certain circumstances. We all know that physical SIM cards need to be inserted and removed from devices, but eSIM can be easily added through a QR code remotely and digitally.

eSIMs simplify the connectivity process while travellers are abroad, making network connectivity on the go. Wherever your adventure leads you, eSIM is always the best way to ensure you stay connected.

Must-have Apps for tourists in Cambodia

Cambodia is friendly but still developing in parts — expect spotty Wi-Fi, cash-first payments, and language gaps outside tourist zones. These apps will help you move around, order food, and communicate easily, even in remote areas.

💡 Pro tip for using Apps in Cambodia

Apps like PassApp and Nham24 may show Khmer by default — look for the English toggle in settings. Also, some mobile wallets (like ABA) are tied to local bank accounts, so stick to apps that accept international cards. Most importantly, download and set up your key apps before arriving and activate your eSIM in advance so you’re not stuck searching for Wi-Fi at the airport.
