Travel eSIMSan Marino
San Marino is the world's oldest republic, a mountain with three towers rising out of the Romagna hills, entirely surrounded by Italy — and not in the European Union. That last detail is the one that catches phones out: a European plan that was free in Rimini may be roaming at full price half an hour up the road. A travel eSIM is a fixed price whichever mast answers.

eSIM plans for San Marino
Online before the bus climbs
There is no airport and no railway: almost everyone comes up from Rimini by bus or car, leaves the vehicle in Borgo Maggiore or at the car parks under the walls, and rides the cable car or walks into the old city. The ticket, the parking payment and the map are all on the phone.
- Before you travel: buy a plan and scan the QR code at home, on Wi-Fi. It takes about a minute.
- On arrival: switch mobile data to the travel eSIM and turn data roaming on for that line.
- Your own number stays active for calls and the SMS codes from your bank. WhatsApp keeps your usual number.
A mountain with a view — and masts on all sides
The republic is sixty-one square kilometres, and the historic centre sits on the ridge of Monte Titano, in plain sight of the plain below. Coverage in the old city, in Borgo Maggiore and in Serravalle on the road down is solid, with 5G on the busier stretches.
It is patchier inside the stone — in the towers, in the narrow lanes under the walls — and on the wooded eastern flank of the mountain, where the cliff itself stands between you and the signal.
Città di San Marino
Piazza della Libertà, the Palazzo Pubblico and the changing of the guard. Good coverage on the squares, thinner in the lanes between them.
The Three Towers
Guaita, Cesta and Montale along the cliff-top path. Fine in the open, weak inside the towers themselves.
Borgo Maggiore
The market town at the foot of the mountain and the lower cable-car station. Reliable signal, and where most visitors park.
The view to the sea
From the terraces the Adriatic coast is laid out from Rimini to Cattolica — a day trip most people combine with the beach.

Inside Italy, outside the EU
San Marino uses the euro and has an open border, so it feels like Italy — but it is not a member of the European Union, and EU roam-like-at-home rules do not reach it. The republic has its own mobile operators, and a European SIM that connects to one of them can be billed at non-EU rates; many travellers find out from the bill.
A travel eSIM costs what it cost when you bought it, on the hill as on the coast.
Check which network your home SIM is on
If you keep a home SIM active, look at the operator name at the top of the screen as you climb. If it changes to a San Marino network, your operator's non-EU rates may apply — turn data roaming off on that line and leave it on only for the travel eSIM.
Coming from Rimini for the day?
If the rest of the trip is on the Adriatic coast, take an Italy plan as well — it covers the beach days, the bus and the drive up.

San Marino: questions before you buy
Is San Marino covered by EU roaming?
Not by law. San Marino is not an EU member, so roam-like-at-home rules do not apply. Some operators include it voluntarily, many do not — check your price list before you go up.
Why was I charged for roaming in San Marino?
Most likely your phone connected to one of the republic's own networks, which your operator bills as a non-EU country. It happens automatically when that mast is the strongest.
Does San Marino have its own mobile networks?
Yes, alongside the Italian networks whose signal reaches the mountain from the plain. Which one a phone picks depends on where you stand.
How do I get to San Marino?
By bus or car from Rimini, about forty-five minutes. There is no railway station and no airport; the nearest are in Rimini.
Is there signal inside the towers and museums?
Weak to none inside the thick-walled towers; fine on the paths, squares and terraces outside.
Do I need a passport or a different currency?
There are no border checks coming from Italy, and the currency is the euro. Cards and phone payments are accepted throughout.
Going further?
