Field tip — Italian SIM likely works without extra charge

Italian SIM cards (especially TIM and Wind Tre) typically work in San Marino without additional charges due to roaming agreements and TIM's physical network presence in the territory. For other EU nationalities, EU RLAH does not apply in San Marino. A San Marino eSIM from Airalo or an Italy-covering plan is the most predictable solution for non-Italian visitors.

Field tip — San Marino is tiny (61 km²); any provider covers all tourist sites

Coverage is complete throughout San Marino — the Three Towers, Piazza della Libertà, Borgo Maggiore and all historic sites have strong 4G/5G. A 1 GB plan is typically sufficient for a full day trip. Most visitors to San Marino use the same eSIM that covers their Italian mainland trip — check that your Italy eSIM covers San Marino specifically.

Network coverage in San Marino

San Marino is a microstate entirely surrounded by Italy. Mobile coverage comes through Italian networks — TIM, Vodafone Italy and WindTre — giving the republic essentially 100% 4G and 5G coverage; Mount Titano (739m) aids signal propagation. There is one catch: San Marino is not in the EU, and it has its own local network that a phone can silently latch onto when you cross the border, triggering international roaming charges even on an EU SIM.

On this page, Roamless and Saily both cover San Marino as part of their Europe/Italy plans and switch to an Italian network automatically — no separate San Marino plan is needed. If you instead rely on a home-carrier SIM, lock the network manually to an Italian operator (TIM, Vodafone IT or WindTre) to avoid the local non-EU network and its roaming charges. Signal is consistent throughout the walled city and along all main roads.

Common questions about eSIM in San Marino

Do EU roaming rules apply in San Marino?
Partially. San Marino has a customs union with the EU but is not an EU or EEA member, so EU Roam Like At Home does not formally apply. Some EU carriers extend Italian coverage automatically; others charge separately. Your phone may auto-connect to an Italian carrier (TIM, Vodafone, WindTre, Iliad) given the enclaved geography. Check your carrier's San Marino terms.
Which network covers San Marino?
San Marino has a local operator (San Marino Telecom) but TIM of Italy is the dominant network due to roaming agreements and geographic coverage. Most travel eSIMs partnering with TIM work seamlessly in San Marino. Coverage is strong throughout the compact 61 km² territory.
