You used to kolmi on my cell phone by João Campolargo Teixeira and Guilherme Sousa consists of a telephone number crafted in argon and a set of 58 audio recordings created as voicemail greetings. The piece is activated when the viewer dials the telephone number. The greetings were recorded daily between February 12 and April 10, 2026, during the exhibition “My Mind is Not a Cage” at Galeria Nave in Lisbon. The call is never answered, and the audio content of the piece changes daily.

You used to kolmi on my cell phone by João Campolargo Teixeira and Guilherme Sousa is part of the series Telephone Sculptures by João Campolargo Teixeira, which references László Moholy-Nagy's Telephone Pictures. You used to kolmi on my cell phone continues the premise of using the telephone as a medium to construct a artwork.

Previously displayed at Cosmos Campolide and Zaratan, in Lisbon.
