Travellers who want a simple, short tourist package and are staying on the main routes.
Cellcard is Cambodia's home-grown network, operated by CamGSM, and the third largest of the four. It has a presence in every province with its strongest coverage in the cities, sells a straightforward tourist package at airport counters, and supports eSIM.

Cellcard is the Cambodian one. Operated by CamGSM, it is the only major network in the country that is not foreign-owned, and it has held its third place through a market where its two larger rivals have far deeper pockets.
For a traveller, the practical case for Cellcard is the simplicity of its tourist pack: one purchase at the airport, a set number of days, and no daily top-up decisions. If your trip is a week in Siem Reap, or the standard Phnom Penh to Angkor run, it does everything you need.
Cellcard is present in all provinces, but presence and depth are different things. Off the main roads its signal thins out sooner than Metfone’s. For a trip built around remote provinces, choose differently.
The tourist pack is sold at the airport counters, which is where most visitors buy it. Cellcard shops in town sell the same SIM, and minimarts carry top-ups. Bring your passport for registration.
