- TIM San Marino (Telefonia Mobile Sammarinese): The republic's own operator, 51 percent owned by Telecom Italia and 49 percent by the state. It runs the network that made San Marino the first state in Europe fully covered by 5G.

eSIM or a local SIM at the airport in San Marino?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter. Data for San Marino starts at $5.99 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your San Marino eSIM
Buy your planYou get a QR code by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Airport and hotel wifi can be weak.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to find the network.
Check the validity clockSome plans start counting at purchase, not at first use. Check before you buy.
Good to know before you land in San Marino
San Marino is not in the EU, and EU roam like home does not officially cover it. Some EU plans bill it as a separate country even though it sits inside Italy, and phones can hop from an Italian network to the Sammarinese one without warning.
There is no airport or railway. The nearest airport is Rimini's Federico Fellini Airport about 10 km away, and a bus runs from Rimini's train station roughly hourly, 7 euros one way as of May 2026.
If your plan covers Italy but not San Marino, lock your phone manually to TIM, Vodafone or WindTre before you arrive. Otherwise pick an eSIM that lists San Marino by name.
