What is the name of the Yo-kai that is a smartphone spirit? The answer is Treetter. Treetter is a Yo-kai associated with mobile-phone technology and is depicted carrying a cell phone.

Treetter belongs to the Shady Tribe and has a tree-based design. The character is listed among the Yo-kai introduced in the franchise's later material, rather than being one of the central characters from the original game.

Tattletell is a different Yo-kai. Her name and abilities relate to revealing secrets and influencing relationships, not to smartphones or cell phones. The alternative names Chatterbox, Telepathy, and Cellphone do not identify the canonical Yo-kai.
