Does the Light Phone III work on TIM?
Yes, it works.
WorksLight's own compatibility checker says the Light Phone III will work with TIM in Italy (it lists TIM, Vodafone, Wind / Tre and Fastweb; checked 23 Oct 2026). Light's spec sheet lists 4G and 5G only, so calls go over 4G Calling.
You should be able to put a TIM SIM in the Light Phone III and make calls, send texts and use data.
