I think the text is clear in the article: You pay 199 THB for the Traveller SIM of AIS.

You get:
 * 7-day "Unlimited" Internet with free 500 MB high speed usage
 * 7-day Unlimited Calls between TRAVELLER SIM 199 Baht users
 * Free 15 Baht bonus with 30 days validity

So whats the credit: 15 THB, 500 MB and free calls.
