There was a time when sending SMS in the Philippines was free. It was a good privilege. But, as usual, some scheming and greedy profiteers preyed on Philippine culture. Business and marketing executives capitalized on the importance of family among Filipinos and how communicating with loved ones is equally - if not more - important than eating rice.
A few years ago, I was a Smart pre-paid subscriber. You see, the country is haven to a few oligarchs whose influence reaches almost every aspect of society, from business to politics. There are 2 or 3 (sometimes 4 or 5) companies vying for a considerable market share given a certain industry. In the field of mobile communication, we used to have 3: Smart, Globe, and Sun. Now, it's down to two, with Smart's acquisition of Sun from a rich Filipino-Chinese clan.
I decided to shift to Globe after realizing that Smart was "stealing" my pre-paid credits. There's no way to retrieve these text and call credits or to complain about how seriously bad their business practices are, particularly in duping customers of what they are supposed to have after paying for it.
