Best eSIM for Cambodia in 2026
Some links on this page are affiliate links. We may earn a commission at no extra cost to you. This never determines how we describe or compare plans.
Quick answer
Cambodia’s cities and main temple sites have good 4G, and a travel eSIM keeps you connected without buying a local SIM on arrival. A 5-10 GB plan suits most trips. If you are heading to remote temples or islands, download offline maps for the gaps.
Networks and coverage
Cambodia’s operators are Cellcard, Smart Axiata and Metfone, all offering 4G. Travel eSIMs typically connect to one of them. Phnom Penh, Siem Reap and Sihanoukville have good coverage.
Coverage is reliable in towns and at the main Angkor sites. Remote temples, the northeast and some islands can have limited or no signal.
City and regional notes
- Phnom Penh - good urban coverage including the airport.
- Siem Reap - reliable coverage around the town and Angkor.
- Sihanoukville - coverage in the city and main beaches.
- Kampot and Kep - good in towns; thinner in the countryside.
- Koh Rong and islands - patchy; check before you rely on it.
What to check before you buy
- Regional plans. A Southeast Asia plan can cover Cambodia, Vietnam, Thailand and Laos.
- Hotspot. Confirm tethering if you need it.
- Calls and SMS. Most travel eSIMs are data-only.
- Currency. Plan prices are often listed in USD.
Practical tips
Install the eSIM before departure and enable it at Phnom Penh or Siem Reap airport. Keep your home SIM active for messages and set the eSIM for data. Guesthouses and cafés have Wi-Fi, but a data plan is useful for tuk-tuks and temple days.
