Here’s how you can register to the unlimited text to all networks of Sun Cellular Philippines:
Featuring TextAll20 where you can send unlimited text messages to your friends using Globe, TM, Smart, Talk ‘n Text, Sun and Red Mobile. All that for 20 pesos valid for 1 day. Just text UTEXTALL20 to 247. Promo is until December 31, 2011. This is 5 peso cheaper than the promo of Smart and Globe but this doesn’t come with free calls and free internet.
