Summary
For a week in Rome, a 10GB Italy eSIM at ~US$12 riding TIMor Vodafone covers maps, Colosseum and Vatican bookings, and day trips to Florence or Pompeii — one nationwide plan, far cheaper than US roaming. Coverage across central Italy is predominantly 4G/5G via TIM and Vodafone, the same networks a local SIM uses.
How Italian networks work in 2026
Three big operators run Italy: TIM, Vodafone, and WindTre. TIM and Vodafone post the widest 4G/5G coverage across Rome and the surrounding Lazio region, with strong 5G in the city centre. Most travel eSIMs ride TIM or Vodafone under the hood, so you get the same towers as a local SIM — plenty for Maps, the Roma metro, museum apps, and video calls.
