According to this you have to go to a B2S or SE-ED book shop to buy,

Topup can be done at 7 Eleven.

Its a type of credit, that you load for your mobile number with the first call.

Repeated calls are simply done by dialing their access number and then your destination number.

Different from other types of PIN systems, where you have to enter the PIN each time before calling.

Be aware that the acess number is a Bangkok fixed line.

So connection cost from your mobile to this access number adds up.
