Cambodia is the majestic temples of Angkor, a moving modern history, riverside capitals and easygoing island beaches. A travel eSIM connects you before you land at Siem Reap (SAI) or Phnom Penh (PNH): buy online, scan a QR code from your email, done. New to eSIMs? Start with what an eSIM is and how it works.
Why an eSIM beats roaming in Cambodia
Roaming from home can mean punishing daily fees or per-megabyte billing. A local-network eSIM is one fixed price for a data bundle, paid up front — nothing to settle later. See eSIM vs roaming: what international data really costs.
Mobile networks & coverage in Cambodia
Cambodia is served by Cellcard, Smart and Metfone. Turnaa plans connect through partners and lock onto the strongest available signal automatically; the operator is shown in each plan’s details drawer. Coverage is good in towns and tourist areas, easing in the countryside.

What to eat in Cambodia
Khmer food is subtle and fragrant. Try fish amok (the national dish), lok lak stir-fry, num pang sandwiches and fresh Kampot-pepper crab.
Local customs, rules & sensitivities
- Dress modestly at Angkor and temples — cover shoulders and knees.
- Greet with a sampeah (palms together); the head is sacred, feet are not.
- Treat the Khmer Rouge history sites with solemn respect.
- Tipping — small amounts are appreciated; US dollars are widely used.
Cambodia data tips from the road

- An eSIM skips the airport SIM counter.
FAQ
How much data do I need for a Cambodia trip?
Maps, ride-hailing and social sit around 5–8 GB for a one-to-two-week trip. See our data guide.
Does it work around Angkor?
Yes — Siem Reap and the temple complex are well covered; remote countryside can drop out.
Do I keep my regular phone number?
Yes — the eSIM is a data-only line; your home SIM stays active for calls and texts, bank codes included.
What if it doesn’t work when I land?
Usually two settings: select the eSIM for data and enable data roaming (see troubleshooting). Support replies fast, and unactivated plans are refundable within 24 hours.
