The smallest state: timed museum tickets, dress code, Ottaviano metro, and why you use an Italy eSIM — there is no tourist SIM shop here.
Des eSIMs sûres, efficaces et privées partout dans le monde
Vatican City is a walled city-state you enter on foot from Rome. There is no tourist hotel strip, no supermarket run, and no 'Vatican SIM shop' in arrivals — because there is no Vatican airport and no consumer mobile counter for visitors. Your phone will roam on Italian networks the moment you walk past the colonnade. An Italy eSIM is the honest product; a Vatican-branded kiosk is a fantasy.
The Museums are a timed ticket and a one-way shuffle toward the Sistine Chapel. St Peter's is a queue and a dress code: shoulders and knees covered, including in heat. Wednesday mornings can mean a papal audience and a different crowd. Sundays the Museums are typically closed; the basilica is not a substitute for the chapel ceiling.
Eat in Prati or Borgo after you exit, not at the first laminated menu on the square. The euro is the currency — the same notes you used for a Roman coffee an hour earlier. This is a half-day or a full museum day, not a country you 'stay in' unless you have a very specific invitation.

Conseils de voyageurs
De vrais conseils de personnes qui sont allées en Vatican City, sélectionnés par notre équipe avec des liens vers les sources d'origine.
You land at Fiumicino or Ciampino like everyone else. Buy an Italy eSIM. Anyone selling a 'Vatican tourist SIM' on the square is selling a story.
Book on the Vatican Museums site. Street sellers with skip-the-line lanyards are a Rome classic. Screenshot the QR; signal dips in the stone.
Shoulders and knees. A light shirt in your bag beats an argument at St Peter's. The chapel is not a beach.
Do the Museums at opening. Eat a normal Roman lunch a few blocks into Prati. The restaurants facing the colonnade are priced for people who will never return.
Check the calendar. A papal audience moves crowds and closures. Sunday is a basilica day, not a Sistine day. Build the rest of Rome around that, not the other way around.
TripAdvisor Forums
You finish the Sistine, exit, and walk around the walls to a separate security line. There is no tourist door from the chapel into the basilica, and the people selling that shortcut are selling a walk you will do anyway.

St Peter's has no admission ticket. The queue is security, and Vatican regulars keep killing products that promise you will float past it. Timed Museums entry skips the ticket desk, not the basilica scan.

Visitors do not shop a Vatican mobile store. You use Italian coverage. Buy an Italy eSIM (or a Europe plan that includes Italy). Unlocked iPhone XS, Pixel 3 or Galaxy S20+ can install it in Rome or at home.
Usually in courtyards and near the entrance; often weakly in deep rooms. Screenshot tickets and a meeting point. This is a coverage quirk of stone, not a Vatican network product.
Treat it as a Rome day: about 1–2 GB for maps, tickets and photos, so a 10-day Italy stash still applies. The chapel is not a streaming venue.
Airport kiosks want a queue and a passport. An Italy eSIM is online for the Leonardo Express and the Ottaviano walk without that desk.
You want Italy (or Europe-including-Italy) on the product page. A listing that only says Vatican City and nothing about Italy is a label to read twice — your radio will still be talking to an Italian tower.
Forfaits eSIM
You will not find a consumer eSIM counter inside Vatican City. Italian networks cover the walk from Ottaviano to the Museums. Install an Italy eSIM before you fly and Fiumicino becomes a train, not a SIM errand.
Screenshot the timed ticket. Stone walls eat signal. The phone's job is the metro map and the QR — the ceiling does not need a bar.
