Terms & Conditions

  • Subscribers must activate roaming service before they leave Cambodia. To activate, dial *1700*313#.
  • The SmartRoam service follows Cambodian time, regardless of the country a subscriber is in.
  • If you live close to the border of a neighboring country, you may attach to that country’s network automatically.
  • You must use the country code to call within the country you’re visiting, or back to Cambodia. Just remember to remove the ‘0’ at the start of the phone number. For example:
  • Available for incoming calls, local calls and calls back to Cambodia. Calls to other countries are charged between 1 USD/minute and 6.60 USD/minute.
  • If you enter a new country, you will need to reach the price cap again to enjoy free data (even if you enter a country on the same day you have already reached a price cap).
