The day-long program, called Champions Together, will feature interactive booths, activity zones, and meet-and-greet sessions with players and coaches from both teams.
Activities open at 12:00 p.m., while the main program starts at 6:00 p.m.
Fans who complete activity passports will have the chance to claim merchandise and secure autographs.
PLDT said the event underscores its continuing support for Philippine sports, with the gathering also available via livestream on PusoP.com.
“Sports have the unique power to connect and inspire communities,” said Jude Turcuato, PLDT and Smart’s first vice president and head of sports.
TNT Tropang 5G, an 11-time PBA champion, and the PLDT High Speed Hitters, reigning PVL Invitational and On Tour champions, are expected to draw thousands of basketball and volleyball fans.
