What matters most
Pick Travel eSIM
Solo or two, 5 days: a travel eSIM is close to the right answer. Install it at home, it connects as you land, and it is usually the cheapest per GB.

Mobile networks in Cambodia
Smart AxiataCellcardMetfone
Cambodia runs on three networks — Smart Axiata, Cellcard and Metfone — and travel eSIMs ride on Smart or Cellcard, the two with the strongest tourist-area coverage. Local SIMs are cheap but require passport registration at a counter; an eSIM installed before you land works the moment you clear immigration at Phnom Penh or Siem Reap airport, which matters because ride-hailing (Grab and PassApp) is how you get anywhere from either terminal.
Phnom Penh, Siem Reap and the Angkor temple zone all have solid 4G — you will have signal at Angkor Wat for sunrise. Coastal Kampot, Kep and Sihanoukville are well covered too. It thins out in the countryside: the Cardamom Mountains, stretches of the Mekong north of Kratie, and the Mondulkiri hills can drop to 3G or nothing, and the islands (Koh Rong, Koh Rong Samloem) have patchy signal away from the main beaches.

Will an eSIM work on my phone?
Two things must both be true: the phone supports eSIM, and it is not locked to a carrier. A locked phone can install an eSIM and still never connect.
Most iPhones from the XS and XR on support eSIM; of those sold in mainland China, only a few recent models do, and inside mainland China an eSIM from abroad cannot be installed. Lock status: Settings → General → About → Carrier Lock should read “No SIM restrictions”.
Menu names differ by maker, and the same model can lack eSIM depending on the country it was sold in. No menu? Use the EID check above.
Answer the two questionsAn EID plus an unlocked phone means a travel eSIM will work.

What to look for in a Cambodia plan
- Days first, data second — a plan that expires mid-trip is worse than one that runs a little low.
- Hotspot/tethering allowed, if you travel with a laptop or share with a partner.
- Which local network it uses — see above; coverage beats a small price difference.
- A top-up option, so you can extend without installing a new eSIM.
- Data-only is normal: most travel eSIMs come without a phone number, and calls happen over WhatsApp or FaceTime anyway.
Good to know in Cambodia
- PassApp and Grab both need data from the moment you land — set the eSIM as your data line before leaving the airport arrivals hall.
- Inside the Angkor Archaeological Park signal is good near the main temples but drops on the remote circuits (Banteay Srei, Beng Mealea) — screenshot your ticket QR beforehand.
- Power cuts happen in the provinces; a phone that tethers a laptop through the outage is often the only internet a guesthouse has.

Frequently asked questions
Will WhatsApp and my phone number still work?
Yes. Keep your home SIM installed and WhatsApp stays tied to your usual number while data flows through the travel eSIM.
Can I share the data with my laptop?
Usually yes, via your phone's hotspot — but some plans block tethering, so check the plan details before buying.
When should I buy and install it?
A few days before departure, on home WiFi. Enable it when you land — unless the plan starts at install, which is why you check the activation rule first.
My phone doesn't support eSIM — now what?
A physical tourist SIM on arrival or a pocket WiFi rental still works fine — the comparison above applies the same way.
Why are there no prices on this page?
Because they change weekly. A price table would mislead you within a month, so we link to live pricing instead.
