Hi I'm Just A student and Internet is a must since Computer Science is my degree, and I would like to ask How to Bypass The Captive Portal In PLDT Since They Sell a tickets 2 hours in worth of 20 pesos which are not enough to load web pages. I would like to ask How do they generating a user name and password so I can Log in to their hotspot. Ang Mahal po kasi ng Pakonek tapos mabagal naman, and everyday halos B-out Sayang lang binabayad ko. I Hope someone could hep me
