How much will it cost for your trip?
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.
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.

eSIM — San Marino
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.

VPN, passwords and documents
San Marino has no significant internet restrictions. A VPN can be useful on public Wi-Fi (cafés, hotels, airports) to keep your browsing private from the network operator.
