Italy’s 5G coverage in 2026 covers all major cities and many medium towns. In practice, 4G is fast enough for everything a tourist needs.
Plan your trip →TIM: best 5G coverage (Rome, Milan, Turin, Naples, Bologna, Florence, Palermo, Catania + 200+ cities). Vodafone: major cities, expanding. WindTre: major cities. Iliad: limited 5G. In practice: 4G covers 99% of populated Italy at 30–80 Mbps — more than enough for maps, streaming, video calls. 5G adds speed (100–500 Mbps) but you won’t notice the difference on a phone.
Mountain valleys (some Dolomites valleys, Sardinia interior, Abruzzo/Molise mountains). Tunnels (trains lose signal in tunnels for 1–10 min). Some islands (Aeolian, Pontine — coverage exists but can be spotty). Download offline Google Maps for your area before going rural.
