I am trying to coordinate 2 different taxis to take me to and from the Cham Yaem border in Cambodia. For anyone who's gone that way, how far does AIS coverage for voice and/or data extend into Cambodia? I will have lots of luggage so communication will be vital at the crossing and maybe a bit beyond it.

If you want to have access further in;

Tap in *125*1# and then press the dial key to enable International Roaming.

If you want to have a data package to keep your communications working; WhatsApp etc

http://www.ais.co.th/roaming/en/package-0.html 99 baht for 2GB over seven days.

 

That will allow you to use up to 2GB of data on
