SIM Cards and eSIMs in Siem Reap

A practical guide to mobile data in Siem Reap using Cambodian SIM cards or eSIMs.

Physical SIM

A local SIM is straightforward if your phone is unlocked.

eSIM

Useful if you want data active before landing or prefer not to swap physical cards.

Coverage

Siem Reap town is easy, but remote day trips can have weaker service depending on the network.

Registration

Physical SIM purchases may require identification, so use official or reputable sellers.

My approach

I would choose the setup that gives reliable data before the first transport or temple day.
