San Marino: Mobile Coverage & Carriers
ESIMBYCOUNTRY at checkout · See all codes →San Marino has mobile coverage provided by two operators: TIM San Marino and San Marino Telecom. The country supports 3G, 4G/LTE, and 5G services. Roaming eSIMs typically connect to LTE band B3 (1800 MHz) and 5G band n78 (3.5 GHz), which are the primary frequencies used for mobile data in the territory.
Some local carriers in San Marino issue eSIMs, though information on this capability is limited. Visitors relying on eSIM connectivity should verify coverage and compatibility with their provider before arrival, as detailed network specifications and carrier eSIM policies remain unclear.

Compiled from public-record telecom facts (the MNO roster, commercially-launched 3G/4G/5G generations, deployed travel-relevant bands and local-eSIM support) and verified June 2026; see the source we compile this country from. Local-eSIM availability checked July 2026 against the major carriers' own pages. This country's connectivity row is low-confidence (small / island / single-operator / fast-changing market): some details could not be confirmed from official sources in our July 2026 check, so treat the carrier, band and 5G specifics as a starting point. How we compile this. Plan prices are supplied by the eSIM provider feed at publish time, not stored here.
