Stored prices may have changed. Google Fi is excluded from the value ranking because it is a full phone plan rather than a travel data plan.
What if it was just $5.00 a GB, everywhere?
We are considering a BetterSIM eSIM at one flat rate worldwide. No tiers, no bundles, no per-country price shopping, no volume discounts you never reach. The same $5.00 in San Marino as in Fiji or Kenya.
Straight answer: this would not be the cheapest option. The plans listed on this page are often less per GB, especially in Europe and Asia. It would be the simplest. Savings against Google Fi depend on usage, Bill Protection and speed needs.
City-by-city connectivity in San Marino
City of San Marino
- Arriving
- San Marino has no airport; the gateways are Rimini (RMI) and Bologna (BLQ), with a direct bus from Rimini up to San Marino holding signal along the route. Most visitors come as a day trip from Rimini or the Emilia-Romagna coast. Any eSIM plan that covers Italy will work here, since San Marino runs entirely on Italian networks.
- On the subway and rail
- The historic centre atop Monte Titano is pedestrian, reached by a cable car (funivia) from Borgo Maggiore that holds cell signal, plus local buses. There is no metro or rail. Coverage is reliable everywhere, including atop the mount and around the three iconic towers.
- Free public WiFi
- San Marino offers free public WiFi to visitors in the historic centre, and the hotels and restaurants provide guest WiFi. Connectivity is easy throughout the tiny republic, a useful supplement to the cellular networks.
- Coverage in the city
- TIM, Vodafone Italy and WINDTRE all provide coverage that extends seamlessly into San Marino, giving strong 4G with 5G in places across the historic centre, the three towers on Monte Titano and the winding medieval streets. The networks are Italian, so coverage is effectively identical to the surrounding region.
- If you prefer a local SIM
- There is no San Marino-specific carrier; the country uses Italian networks. Any Italy or European regional eSIM plan covers it, which is the simplest approach. If visiting as a day trip from Rimini, your Italy plan already covers both.
Local Network Insights
Grab an eSIM before you arrive in San Marino to skip local SIM queues. Most urban areas offer 4G or better, while rural regions can slow down, so keep offline maps handy. Activating the eSIM in advance ensures you are connected the moment you clear customs.
Connectivity Overview
San Marino, the world's oldest republic, is a tiny landlocked microstate entirely surrounded by Italy. At just 61 square kilometers, it relies on Italian mobile networks for its connectivity. TIM, Vodafone Italy, and WINDTRE all provide coverage that seamlessly extends into San Marino, giving visitors strong 4G throughout the country and 5G in some areas.
For eSIM travelers, this is excellent news - any plan that covers Italy will almost certainly work in San Marino without additional charges. EU roaming regulations effectively apply through Italy's network infrastructure. Most visitors come to San Marino on a day trip from Rimini or Bologna, so a broader Italy or EU plan is the practical choice. The historic center perched atop Monte Titano has reliable coverage, and you will stay connected while exploring the three iconic towers and the winding medieval streets.
Practical Data Tips
- San Marino uses Italian networks - any eSIM plan covering Italy will work here
- EU roaming applies through Italian network infrastructure
- If visiting as a day trip from Rimini or the Emilia-Romagna region, your Italy plan covers both
- Coverage is reliable everywhere in the country, including atop Monte Titano
- Free Wi-Fi is available at most hotels and restaurants in the historic center

View Saily options · Official sourceBefore you fly: a 6-step checklist
- 1
Buy and install at home on WiFi.
Installation is not the same as activation. You can install the San Marino eSIM days ahead and only switch it on after you land, which avoids burning days of validity in transit.
- 2
Screenshot your current APN before you swap.
If you ever need to switch back to your home line quickly, that screenshot saves a support call from a foreign airport.
- 3
Choose your travel data line.
On iPhone, select your travel eSIM in Settings > Cellular > Cellular Data. Follow your provider's roaming and activation instructions. Choosing a data line does not by itself prevent charges on your home line.
- 4
Decide whether to keep your home line on.
You do not need to disable iMessage simply because you use a travel eSIM. Apple’s travel eSIM guidance says iMessage and FaceTime can continue using your home line while traveling. If you keep both lines active for home-number calls or SMS, your carrier may charge roaming fees. Check your carrier’s terms before leaving your home line on.
- 5
Download offline maps for San Marino.
Google Maps and Apple Maps both support offline regions. Pull them down on home WiFi so a flaky activation never leaves you without a route from the airport. Our offline maps guide walks through it step by step.
- 6
Activate at the airport, not before.
Once the validity timer starts it does not pause. A 15-day plan you turn on the morning of departure burns a full day of validity before you even land.

How we built this page
Country plan prices come from stored supplier snapshots. The catalog contains different data amounts and validity periods. Provider ordering uses the unweighted average $/GB of fixed plans, or the PAYG rate; unlimited plans are excluded from that average. Check a plan’s data, validity and total price against your trip before buying.
