Your Cambodia eSIM in two questions
Which Cambodia eSIM plan do I need?
Cambodia's networks run on 4G, so pick your plan by how many days you'll stay and how much you'll use your phone.
- A three-day city break in Siem Reap: Pick 2 GB for 15 days. That gives room for maps, messages and a few video clips while you explore by day.
- A fortnight touring Phnom Penh, Kampot and Battambang: Pick 10 GB for 30 days. You get room for maps, social media and some video as you move from city to city.
- A trip that also takes in a neighbour: The South East Asia bundle covers Cambodia and seven other countries, so one eSIM can take you across the border. Check the South East Asia bundle.
- A month-long stay: Pick 20 GB for 30 days. That leaves room for social media, music and some video across the month.
Most plans can be topped up, and the longest plan lasts 30 days, so you can top up your eSIM if needed.

Will my eSIM have signal in Cambodia?
Your eSIM joins Cellcard or Metfone, the two networks you'll find across Cambodia. Both run on 4G, so that's the connection you'll get, and your phone picks between them by itself. Cities and main tourist areas are well covered, though signal can be patchy in remote rural areas. Once you're connected, Grab and PassApp are the ride apps to have ready.
Your data reaches the internet through Singapore, a normal setup for travel eSIMs, and you can read more on the IP address page. Daily plans slow to 512 Kbps once you've used that day's allowance.
How much data do you need in Cambodia?
Light: maps, messages, email (about 0.25 GB a day). Standard: plus social, music, some video (about 0.7 GB a day). Heavy: plus streaming, video calls, hotspot (about 1.8 GB a day).

Cambodia eSIM questions
How much is an eSIM for Cambodia?
Cambodia eSIMs start at £3.99 for 100 MB over 7 days. A 5 GB plan for 30 days costs £9.99. Prices include any taxes and show in pounds, euros or dollars.
Which networks does the Cambodia eSIM use?
Your eSIM connects to Cellcard and Metfone in Cambodia. Your phone picks the strongest signal automatically.
When does my Cambodia eSIM start?
Most plans start the moment your eSIM first connects to a network in Cambodia, so you can buy and install it at home before you fly. Install it within 180 days of buying.
Can I top up my Cambodia eSIM?
Yes. Most Cambodia plans can be topped up from your eSIM page in two taps, with no new QR code. The plan table on this page shows which ones.
Why does my IP address show another country?
Cambodia plans route your data through Singapore, a normal setup for travel eSIMs. Websites and apps may show that country's content; your speed and coverage in Cambodia are not affected.
Does it come with a phone number?
Every eSIMology plan is data only. Keep your own SIM switched on for calls and texts, and use WhatsApp, FaceTime or any calling app over your eSIM's data.
What if my plans change?
Cancel an eSIM you haven't installed within 30 days for a full refund to your card, in two taps from your eSIM page.
Is there 5G in Cambodia?
No, Cambodia's networks run 4G rather than 5G, so your eSIM will connect on 4G. That's plenty for maps, messages and booking a ride in Siem Reap or Phnom Penh.
Does Grab work with an eSIM in Cambodia?
Yes. Grab and PassApp both need mobile data to book, so your eSIM is what gets you from Siem Reap-Angkor (SAI) to your hotel. Set your pickup pin before you head out.
Which eSIM covers Cambodia and the countries around it?
The South East Asia eSIM covers a group of 8 countries that includes Cambodia, so one plan can cover a trip that crosses borders. Buy one for the whole route rather than a new one at each border.
What happens when my daily data runs out in Cambodia?
On a daily allowance plan, your data drops to 512 Kbps once you've used that day's amount. That's still fine for messages, so save big downloads and video for hotel Wi-Fi.
Do I still need an eSIM if hotels in Cambodia have free Wi-Fi?
Yes, you do. Free Wi-Fi is common in hotels, cafés and restaurants in tourist areas, but it stays put. Your eSIM covers the in-between moments, like messaging a friend or checking a map on the street.
Which messaging apps should I have ready in Cambodia?
Telegram and Facebook Messenger are the ones to have ready in Cambodia, for chatting with locals, guides and hosts. Both need mobile data, so your eSIM keeps them going once you're out and about.
Ready for Cambodia?
Buy now, install today, and your plan waits until you land. Full refund if not installed.
