i received a bogus sms for the first time this afternoon asking for a 5 peso load indicating that it was a new number without stating who it was.  I tried to call the said number but i received a "network busy."  i recalled an issue before where some syndicates were able to make use of a postpaid line triggered by just dialing a number from the end of the phone owner so i inquired through customer service just to prevent the hassle when i receive my phone bill.  they said that it's not possible to control a postpaid line (i have no idea about this) and informed me about these bogus sms just asking for a free load.
