The Chosen Children recieved their Digivices: when they met with their Partner Digimon. They materialized out of nowhere, and were then used by them for their various abilities, most importantly to evolve their Partner Digimon.

After learning of the secret of the Crests from Wisemon in "The Mystery Hidden Within the Crests", the Digivices: showed arrows, pointing the Chosen Children in different directions which they followed in order to find said secret.

While normally white with coloured lights upon being used, the Digivices: turn into the colour of the Chosen Child's respective Crest once they get closer to figuring out the secret of said Crests, normally when they obtain their Ultimate-level evolutions. As well, while the Digivice: normally merely shows the Chosen Child's Crest in its screen when they show their Crest's trait, once they change colours, the Crest is projected from the Digivice: instead.
 * 1) It first happened to Tachikawa Mimi in "The Digimon School Under Attack", after Lilimon evolved into Rosemon and defeated Bancho Mamemon.
 * 2) It happened to Ishida Yamato in "The Gold Wolf of the Crescent Moon" after him and Were Garurumon: Sagittarius Mode managed to reawaken the gold sword fighter's weapon, which then caused the latter to evolve into Cres Garurumon to fight Zanbamon.
 * 3) Yagami Hikari accomplished it in "Hikari, New Life", after the Digitama she was protecting hatched into Nyokimon. This caused Angewomon to project an Ofanimon aura, powering her up to the point where she could defeat and purify the Skull Baluchimon who had beat her earlier, as well as a group of Soulmon, returning them all to Digitama.
 * 4) Izumi Koshiro accomplished it in "Bolt, Herakle Kabuterimon", after realizing that his friendship with Tentomon was knowledge. This allowed Atlur Kabuterimon to Ultimate Evolve into Herakle Kabuterimon, giving him the strength to easily defeat Nanomon and Gran Kuwagamon.
 * 5) It happened to Kido Joe after his leadership qualities were recognized by Olegmon and his crew, alongside the hot spring crew, Bancho Mamemon and Gomamon in "Vikemon Ventures the Glaciers".

Adventure:'s Yagami Taichi has his Digivice: with him when he's transported to the V-Tamer Digital World. After he and Agumon decided to keep fighting in spite of being overpowered, the Crest of Courage appeared in the eyes of both himself and V-Tamer's Yagami Taichi. This filled the Digivice: with energy, causing it to glow. Adventure:'s Taichi then raised the Digivice: to the sky and called out that it was time to evolve, which created a massive Crest of Courage in the sky that evolved Zeromaru and Agumon into Ulforce V-dramon Future Mode and an incomplete War Greymon, respectively, which gave them enough power to destroy the polyhedron.
