TIM, Wind, TIM maritime and Iliad coverage in San Marino
HelloRoam sells eSIM plans for San Marino. San Marino has no visitor mobile network of its own, which is why the Italian partner list decides what you get here: HelloRoam runs its San Marino eSIM on TIM, Wind and Iliad, with TIM maritime covering the coastal edge on 3G. TIM, formerly Telecom Italia Mobile, and Wind carry the bulk of the 5G capacity, and Iliad adds a third layer.
The republic does run its own operator, SMT, for domestic lines, but international visitors ride the Italian carriers exclusively. All of it is European-standard service across the whole territory, because every tower sits within a few kilometers of the border.
Coverage analysis
Coverage reaches every part of San Marino from Italian towers just across the frontier. The historic center on Monte Titano, the Three Towers of Guaita, Cesta and Montale, and the lower towns of Borgo Maggiore and Domagnano all carry strong signal. Piazza della Liberta, the duty-free shopping district and every tourist site hold steady service.
The switchback road up from Borgo Maggiore keeps signal on every bend, and the cable car between the two levels stays connected end to end. No dead zone exists, because the country is 61 sq km of open hillside ringed by Italian infrastructure.
Activation
Install the eSIM QR code before you travel to Italy, which is the gateway country for San Marino. TIM, Wind, TIM maritime and Iliad register on Italian towers well before you cross the frontier, so there is no border formality and no local registration to complete. The profile works from Rimini through the countryside and up into San Marino on one plan. iPhone XS or newer, Pixel 3a or newer, and Galaxy S20 or newer all support eSIM.
Your device must be carrier-unlocked before departure. No local SIM registration exists in the republic, so the SIM question is settled in Italy before you arrive.
Data usage tips
San Marino visits are usually day trips from Rimini or the Italian Adriatic coast, running 3 to 6 hours. Most visitors use 200 to 400 MB in total for Google Maps up the switchback road, TripAdvisor for tower tickets, and photo uploads from the battlements. The 1 GB plan at $1.14 covers a day trip several times over.
The 3 GB plan at $3.20 suits travelers adding San Marino to a wider Italy itinerary, since the same Italian networks carry them across the region.
eSIM plan pricing in San Marino
San Marino sits at the low end of European eSIM pricing, because the plans ride Italy's competitive network market. The 1 GB plan costs $1.14 for 7 days, 3 GB costs $3.20, 5 GB costs $4.78, 10 GB costs $8.56, and 20 GB costs $18.08. A 1-day plan costs $2.40 and carries a 2 GB daily allowance with a fair-use speed reduction past it.
Across all 6 plans the rate bottoms out at $0.86/GB.
No verified Airalo, Holafly or Saily price for San Marino exists in this repository, so this page publishes no head-to-head price claim.
