We saw some of their sister telco's latest moves of their prepaid promos with landline calls to PLDT. No wonder that Sun Cellular also had that move recently when I saw this both on some tarpaulins and online ads.
This is the 2017 edition of Sun Cellular TU200 which is for 200 pesos, you will get a thousand of all-net texts, unli Sun texts, free access on some chat apps like Facebook and five hours of calls which you can use to call to PLDT landline, Sun, Smart and TNT valid for 30 days
To register, just text TU200 and send to 247. No official words yet on the end of the promo date of TU200
