These include parts of Sarangani (Malungon, Alabel), Davao Oriental (Governor Generoso, San Isidro, Mati City, Banaybanay, Lupon, Baganga, Cateel, Boston), Surigao del Sur (Hinatuan, Bislig City, Lingig), Agusan del Sur (Trento, Bunawan, Rosario), Surigao del Norte, Zamboanga del Norte, Zamboanga del Sur, Misamis Occidental, Zamboanga Sibugay, Sultan Kudarat, Maguindanao del Norte and del Sur, North Cotabato, Cotabato City, Davao City, Dinagat Islands, and Lanao del Norte (Kolambugan, Maigo).
