[5] In December 1995, Omnitel Sistemi Radiocellulari Italiani (founded on June 19, 1990, by Olivetti, Lehman Brothers, Bell Atlantic and Telia) and Pronto Italia (made up of Zignago Vetro, AirTouch, Mannesmann, Banca di Roma, Arca Merchant, Comeba, Ersel, Erg, Urmet TLC, Spal TLC, Site, Ponti Radio and Fergia[6][7]) merged into Omnitel Pronto Italia,[8] which launched a mobile telephony service, the second in Italy after TIM (formerly SIP).

[9] Olivetti, the original majority shareholder, through Omnitel and Infostrada (which dealt instead with fixed telephony), thus competed with Telecom Italia, which until then monopolized the entire telecommunications sector in Italy.

On 16 December 2013, following Verizon's sale of the entire share capital held in the company to Vodafone, it was transformed into a besloten vennootschap (B.V.).

On March 15, 2024, Swisscom announced its intention to acquire 100% of Vodafone Italia for €8 billion, with the closing expected to take place in the first quarter of 2025, integrating it with its subsidiary Fastweb.

As part of the agreement, Vodafone will continue to provide certain services to Fastweb, including brand licensing, for up to five years.

[20] Swisscom announced that the European Commission had approved the acquisition of Vodafone Italia under the Foreign Subsidies Regulation.

[22][23] In October 2024, CoopVoce signed an agreement with Vodafone to extend mobile network coverage and implement 5G.

[24] On November 15, 2024, Sabrina Casalta, the company's Chief Financial Officer, was appointed interim CEO, replacing Aldo Bisio, who remained a non-executive board member until the completion of the transaction with Swisscom.

[citation needed] As of June 30, 2016, about 150 of these operators in 100 countries allow customers to reach 4G LTE coverage.
