The Transformation Cellular Go-Phone (変身携帯ゴーフォン Henshin Keitai Gōfon?) is a device that only Sosuke (Go-On Red), Saki (Go-On Yellow) and Renn (Go-On Blue) can use during the series. It has various functions such as transforming them to the Go-ongers by inserting the blue Change Soul in the phone and by saying the transformation phrase "Change Soul, set! Let's Go-On!" (チェンジソール、セット！レッツゴーオン！ Chenji Sōru, setto! Rettsu Gō-On!?) and combining their respective Engines into Engine-O, as well as Engine-O G6 and Engine-O G12.
