Our Method
San Marino eSIM scoring, category by category
We score five eSIM providers for San Marino, all of which sell plans on TIM's 5G network. Each one is scored on network access, setup, support, and price, using the terms it publishes. San Marino presents a 4G-dominant connectivity environment, so the carrier a provider routes through matters more here than the brand on the checkout page.
Methodology
How this San Marino guide is built
Where the data comes from
This guide covers 4 eSIM providers that sell plans for San Marino. Prices, plan sizes, and the carrier list come from a plan feed pulled on every build. Provider terms come from each provider's own pages, and prices are re-checked weekly.
What we do not publish
We run no speed tests, so this page has no Mbps figure for any provider in San Marino. We do not time support desks either, so no reply window appears here. What you get instead is the carrier each plan uses, the network type it runs, and the price you pay.
Network Data

Operator Data
Operators carrying your eSIM: San Marino
One network or several changes what happens when the signal drops. Here is the list, straight from the source.
HelloRoam publishes four local operators for San Marino: Iliad, TIM, TIM maritime or Wind. Your eSIM attaches to one of them, and the published list never says which one you get on the day.
HelloRoam labels three of them 5G in San Marino and the rest 4G. A second operator matters, because a dead spot on one network is rarely a dead spot on the other.
| Local operator | Network listed |
|---|---|
| Iliad | 5G |
| TIM | 5G |
| TIM maritime | 3G |
| Wind | 5G |
Operators are listed alphabetically. The order is not a ranking and not a routing order.

Arrival
San Marino arrival with the eSIM already installed
Install the profile before you fly, then turn airplane mode off after landing at the international airport and the eSIM attaches to TIM. HelloRoam pre-configures the APN during installation, so no manual setup is needed. Some providers ask you to pick the network by hand on Android. Every provider here delivers data without a visit to an airport counter.
Networks
San Marino carrier network analysis
San Marino's mobile infrastructure runs on TIM, WindTre, and Iliad, with 5G as the top network type in our plan feed. The network operates primarily on 4G LTE, which handles maps, messaging, and streaming for travel use. Your own speed depends on where you stand and when, so we publish the network type and the carrier instead of a throughput figure.
Network Type
What 5G Means for Your Trip to San Marino
A 5G connection on TIM in San Marino covers what travelers actually do: video calls, maps, messaging, social media, and streaming. A travel eSIM on TIM rides the same towers as a local SIM on TIM, so neither format has a network advantage over the other.
Southern Europe
Southern Europe Connectivity: San Marino in Context
Southern European destinations attract massive tourist volumes that strain mobile networks during peak season. Beach resorts, historic city centers, and popular islands in San Marino experience network congestion from June through September. TIM's network handles the load but speeds drop 15-25% in the most visited areas during peak hours.
Coastal and island coverage in San Marino is generally good at established resort areas. Smaller islands and remote beaches may have weaker signal. TIM's tower density along popular coastlines is sufficient for navigation, messaging, and social media. Streaming quality depends on proximity to the nearest tower.
Rural Coverage
San Marino coverage beyond the big cities
TIM provides the widest rural coverage in San Marino. Rural areas have adequate but slower coverage. Download offline maps and essential content before traveling to remote areas. A travel eSIM rides whichever carrier its provider has an agreement with, and no carrier in San Marino eliminates every rural dead zone.
eSIM vs Local SIM
San Marino local SIM card against an eSIM
Local prepaid SIMs in San Marino cost a comparable rate and are available at local shops. A travel eSIM at $0.86/GB removes the queue, passport requirement, and SIM swap. No SIM registration is required, but the convenience advantage of eSIM remains significant. For trips under two weeks, a travel eSIM is the more practical choice.
Timing
Tourist Season Impact on San Marino Connectivity
Network performance in San Marino varies by season. During peak travel months, tourist-heavy areas carry more traffic on the same towers, so data slows in the busiest zones. Buy one data tier above your estimate for a peak-season trip. Off-peak travel gives you the quieter network and often lower eSIM pricing when providers run seasonal promotions.
