TRIO 20 Unli Service Introduced, Lets You Call and Text to Smart, Sun Cellular and Talk N Text


After Smart Sun Dual 549, the Smart-Sun Cellular merger has introduced another service involving both networks, and this time Talk N Text is joining.

The new service is called Trio 20 and it’s a form of an “unli” service involving the three afore-mentioned networks.  This is the first such service in the Philippines and it’s made possible only because of the PLDT-Sun or Smart-Sun merger.

Trio 20 is a prepaid package that lets subscribers send texts and make calls to Smart, Sun and TNT networks for only P20 in a single day.  This package includes 200 text messages and 15 minutes of calls to any of the three networks.  To avail of the service, you only need to text “Trio20” to 2477.

We should probably expect more services and products like this following the Smart-Sun merger.  The first one was Smart Sun Dual Plan 549, a postpaid offering, which offered unlimited Smart-to-Smart and Sun-to-Sun text messaging, 6 hours of free voice calls, and a free Nokia C2-03 phone. is one of the most active tech sites in the Philippines.

  1. nag register po ako…bakit nman di nakakatawag? lagi sinasabi ng phone” rejected” or disconected… nagtry ako tumawag to my sun#, smart# for a test, and sun & smart friends number…nag expired nlang po….”Hindi ko nagamit”..15mins call was not working..

  2. dali nga magregister ng unli sa smart, dka naman makatawag.. sayang lang pinag register mo.. buti pa globe, hirap mag register, pro once nakapasok, pasok lahat ng tawag.. sulit na sulit..
