Rome layers 2,800 years of city on top of itself, and modern navigation is how you thread it, Colosseum time slots, Vatican queue intelligence, and the eternal question of whether that trattoria is a gem or a trap (reviews know). TIM and Vodafone cover the historic center completely, catacombs excepted.

FCO's SIM counters involve passport registration and €25-30 starter packs, the full Italian bureaucratic experience as a welcome. The Leonardo Express into Termini is covered; an installed eSIM has your first carbonara researched before the train moves.
Mobile coverage in Rome: what to expect
Strong across the centro storico, Colosseum, Forum, Trastevere, Vatican City (Italian networks cover the world's smallest country seamlessly). Metro lines A and B have station coverage with brief tunnel gaps. The catacombs and the Vatican Necropolis are offline, as befits their residents.
Rome data tips from the ground
- Colosseum and Vatican tickets are timed-slot warfare, official-site drops and last-minute returns need live data and reflexes; the walk-up queue is where holidays go to die.
- Rome's traffic makes buses unpredictable, live transit apps or walking (the center is compact) beat schedule fiction.
- The water fountains (nasoni) are mapped in apps, free ice-cold refills across the city, the Roman Empire's best surviving infrastructure.

Does my Italy eSIM work inside Vatican City?
Yes, the Vatican has no mobile network of its own; Italian carriers cover St. Peter's and the museums seamlessly. The Sistine Chapel's no-photo rule is enforced by guards, not signal blockers.
Is there signal in the Colosseum's underground and the catacombs?
The Colosseum's arena and stands: full signal. The recently opened hypogeum (underground): patchy. The catacombs along the Appian Way: none at depth, surface for the map check.
How much data for 4 days in Rome?
1.5-2GB, navigation through the tangled center, ticket apps, translation and reviews. Roman hotel Wi-Fi ranges from excellent to 'the palazzo's walls are 500 years thick'; the eSIM bridges the gaps.
