Italy’s telecoms regulator Agcom has opened an investigation into integrated fixed-mobile services which some local operators, including Telecom Italia, plan to launch. The authority says its probe will last 120 days and it will examine whether firms such as TI, which operates both wireline and wireless networks, gain a competitive advantage over pure fixed line or cellular operators. TI plans to introduce an integrated handset dubbed Unico in July, which will function like a cordless handset in the home and like a GSM phone outside. Subscribers will pay EUR15 a month for unlimited free calls from home, with GSM calls to two wireline and one cellular number also being free of charge. Operators such as Vodafone and FastWeb have also expressed an interest in offering fixed-mobile packages.
