Mobile coverage in San Marino
San Marino's mobile network is served by San Marino Telecom and benefits from proximity to Italian network infrastructure, with operators including TIM and Vodafone Italy also providing coverage across parts of this tiny landlocked republic. 4G LTE coverage is available across the City of San Marino, Serravalle, Borgo Maggiore, and the main accessible areas of the country. San Marino covers just 61 square kilometres and sits on Monte Titano entirely surrounded by Italy, meaning coverage is generally consistent across the main settled and tourist areas. The higher fortress towers and some cliff-edge paths may have slightly variable signal. MobiSIM connects through supported local networks to deliver reliable data throughout San Marino's main areas during your visit.
