^^^Yeah. Can't do unlimited pag postpaid subs ka. They have 2 kinds of postpaid accounts- Gold and Consumable.
Pag consumable, yung services such as text, calls, and yung mga texts sa Chikka, YM, mga games, downloads, contests, etc., covered na nung plan. Bale yung plan mo kino-consume mo lang for a fee depending on your plan. Halimbawa, pag naka-Plan 800 ka, ang text is more than P/1.00, so lugi diba?
Whereas sa Gold naman, for example, Plan 500 ka, meron kang 500 na text tapos may 20mins na free call, then yung ibang services such as texts to Chikka, mga contests, downloads, GPRS, etc., will be added to your bill, on top of the plan.
Pasaload is on top of Plan, and for roaming, you will have to pay P/2,500.00 as deposit, tapos lahat ng transactions pag naka-roaming, on top of plan lahat. Luging-lugi as compared pag naka-prepaid.
Ang advantage lang ng naka-plan is mas mura ang International SMS. Pag prepaid diba P15.00, pag naka-plan, 10.00 lang.
