How to install your San Marino eSIM in 3 steps
San Marino has no airport of its own, so travelers usually arrive by road from Italy - which makes it worth having data ready before you cross the border rather than hunting for a shop once you're on Monte Titano.
- Buy your San Marino eSIM online from £0.99 and get a QR code by email - no shop visit and no ID check required, unlike a local SIM.
- Scan the QR code in your phone's eSIM settings while you still have Wi-Fi, ideally before you leave home or while passing through Rimini or Bologna airport on the way in.
- Enable data roaming for the new eSIM profile once you're in San Marino, and your phone will pick up a signal as it settles onto the local network around San Marino City or Borgo Maggiore.
Because the whole country covers just 60 square kilometres, once your profile is active you're rarely more than a short walk from a working connection, whether you're touring the historic center or riding the cable car down to Borgo Maggiore.
Coverage in San Marino
Mobile service in San Marino runs through TMS (Telefonica Mobile Sammarinese), the sole domestic operator, majority-owned by Telecom Italia. Rather than building fully independent infrastructure, TMS leans heavily on the Italian TIM network, which lets it reach nearly the entire population across this small, mountainous territory. Vodafone Italy and Wind Tre also broadcast into San Marino from towers just across the Italian border, adding extra 5G and 4G/LTE coverage in and around the capital.
5G is available across the whole territory and reaches all of San Marino's populated centres, including the UNESCO-listed historic center on Monte Titano. Vodafone Italy layers in additional 5G coverage specifically in the main City of San Marino urban area.
The catch is the terrain: Monte Titano's peaks rise to around 756 metres, and San Marino's compact size means phones frequently hand off between the Sammarinese TMS network and Italian towers as you move between the old town, Borgo Maggiore, and the surrounding hillsides. This handoff is generally seamless for data, though it can occasionally trigger unexpected roaming charges on a plan that isn't built for the mix of networks. There are no rural dead zones in the usual sense, but coverage on exposed ridge walks can vary with the rock face rather than staying constant.
How much data do you actually need?
Match your trip to a plan size using how you expect to use your phone day to day:
| Usage level | Typical daily use | Suggested plan | Good for |
|---|---|---|---|
| Light | ~300MB/day (maps, messaging) | 1GB / 7 days | A short weekend around the historic center and Guaita Tower |
| Moderate | ~750MB/day (social media, some calls) | 3GB / 30 days or 10GB / 30 days | A week or more exploring San Marino City and Borgo Maggiore |
| Heavy | 1.5GB+/day (navigation, video calls, streaming) | 10GB / 30 days or 20GB / 30 days | Extended stays or working remotely from San Marino |
eSIM vs roaming vs a local SIM
Here's how the three options actually compare once you factor in San Marino's ID rules and its dependence on Italian networks:
| Option | Setup | Typical cost | Best for |
|---|---|---|---|
| eSIM (this plan) | Install the QR code online before you travel - no shop, no ID | From £0.99, cheapest 1GB option from £0.99 | Most visitors, including day-trippers from Italy |
| Home carrier roaming | Automatic, but San Marino sits outside EU roaming agreements | Often £8-£11 a day, with occasional much larger weekly bills | Only if you'll barely touch data |
| Local SIM (TMS or TIM shop) | In person in San Marino City or Borgo Maggiore, passport or ID required, with a short registration step | Local rates, but costs the time to visit a shop | Longer stays or anyone settling in for work |
Practical connectivity tips
Keep your phone set to automatic network selection rather than locking it to one carrier - since TMS coverage leans on Italian TIM towers, letting it choose freely usually gives the strongest signal as you move between San Marino City, Borgo Maggiore, and the hillside towers. If you're heading up to Cesta Tower or along the Passo delle Streghe ridge trail, download offline maps first, since exposed mountain routes can see coverage dip depending on which side of Monte Titano you're on. Emergency calls to 112, 115, or 118 will still connect even without an active SIM, so don't panic if your data profile hasn't kicked in yet. Because San Marino has no commercial airport, most travelers pass through Rimini or Bologna first - activate your eSIM profile there or before you leave home so you're not troubleshooting settings on arrival. Finally, if you notice your phone briefly showing an Italian carrier name while you're clearly inside San Marino, that's the normal cross-border handoff at work, not a sign anything's wrong.

Frequently asked questions about eSIMs for San Marino
Why does my phone keep switching between two different networks in San Marino?
San Marino is a 60 sq km microstate, so as you move around Monte Titano your phone can hop between the local operator, TMS, and Italian towers such as TIM, Vodafone Italy or Wind Tre broadcasting in from just across the border. This handoff is normal and usually harmless, but it's worth checking your eSIM plan covers both networks so you don't get caught on an unexpected roaming rate.
Is San Marino covered by EU roaming rules?
No. San Marino is not an EU member state, even though it uses the euro, so standard EU "roam like at home" rules don't technically apply here. Coverage comes largely through Italian infrastructure, which can leave a grey area on some home-carrier plans - a San Marino-ready eSIM avoids the guesswork.
Will I get signal from the top of Cesta Tower or along the Passo delle Streghe ridge?
Coverage reaches all of San Marino's populated centers, but the terrain is genuinely mountainous - Monte Titano's peaks rise to around 756 metres. Along exposed ridge routes like the Passo delle Streghe, expect signal to vary with the rock face rather than assume a constant connection.
Do I need my passport to buy a local SIM in San Marino?
Yes. Local SIM registration follows the same ID-check rules used across the region, so TMS and TIM shops in San Marino City and Borgo Maggiore will ask for a passport or valid ID, and in-store activation involves a short wait. An eSIM bought online skips this step entirely.
What number should I call in an emergency in San Marino?
Dial 112 for police or general emergencies, 115 for fire, or 118 for an ambulance - all three work even without an active SIM, and 112 has English-speaking dispatch available.
Is there 5G around the historic center of San Marino?
Yes, the country's 5G network covers the whole territory, including the UNESCO-listed historic center with its 11th to 14th century towers, and runs on Nokia-supplied equipment. Vodafone Italy also adds 5G coverage in the main City of San Marino urban area.
Can I use my eSIM before I even reach San Marino, since it has no airport?
San Marino has no commercial airport, so most visitors transit through Rimini, about 30km away, or Bologna. Both can have patchy connectivity in spots, so it's worth installing your San Marino eSIM profile over airport Wi-Fi before you land rather than waiting until you're on the ground.
Who actually runs the mobile network in San Marino?
TMS (Telefonica Mobile Sammarinese) has been the sole domestic operator, majority-owned by Telecom Italia, running largely on Italian TIM infrastructure to reach nearly the whole population, including the highland areas around Monte Titano.
Could I get charged roaming fees just from my phone briefly connecting to an Italian tower?
It's possible. Because San Marino's network relies on nearby Italian towers, a phone can latch onto TIM, Vodafone Italy or Wind Tre for a moment even while you're standing in San Marino City, and depending on your home carrier that split-second connection can trigger non-EU roaming rates. A local eSIM data plan sidesteps this entirely.
Is data coverage as good in Borgo Maggiore as in the old town on Monte Titano?
Yes - Borgo Maggiore, the lower town and cable car hub, sits within the same near-nationwide coverage footprint as the historic center above it, just with quieter streets and smaller crowds.
