Touch down at Siem Reap or Phnom Penh and your phone is already online, ready to call a tuk-tuk, map your way to Angkor Wat, or message home. That is the magic of a travel eSIM for Cambodia.
Why use an eSIM in Cambodia
A local SIM means queuing at the airport, showing your passport, and swapping out your home card. An eSIM skips all of that. You buy it before you fly, scan a QR code, and switch it on the second you land.
- No roaming charges or surprise bills
- Keep your home number active for calls and texts
- Instant delivery to your inbox, set up in minutes
- Top up or change plans without a physical card

Cambodia has strong, modern mobile networks. The main operators are Smart, Cellcard, and Metfone, and our eSIM connects to the best available signal automatically.
- 4G is fast and widespread in cities and tourist hubs
- 5G is live in Phnom Penh and growing in Siem Reap
- Reliable coverage in Sihanoukville and along the coast
- Rural and temple areas have solid 4G, though remote jungle spots can be patchy
How to get connected
1. Buy your Cambodia eSIM online and receive the QR code by email 2. Scan the QR in your phone settings to install the data plan 3. Enable the eSIM and turn on data roaming for that line when you arrive
That is it. Most travellers are online before they leave the airport.
How much data do you need
- Light (maps, chat, email): 1 GB per week
- Medium (social media, browsing, some video): 3 to 5 GB
- Heavy (streaming, hotspot, video calls): 10 GB or more
Wi-Fi is common in hotels and cafes, so many travellers do well with a mid-size plan.

FAQ
Is my phone compatible? Most phones from the last few years support eSIM, including recent iPhone, Samsung Galaxy, and Google Pixel models. Check your settings for an eSIM or add-data-plan option.
When should I install it? Install at home over Wi-Fi before you fly, then simply switch it on when you land. You can set the activation to begin on arrival.
Can I keep my WhatsApp number? Yes. WhatsApp is tied to your original number, which stays active. The eSIM only carries data, so your account and chats work exactly as before.
