San Marino eSIM Matrix, Sorted by Stay Length (2026)
HelloRoam publishes 4 local operators for San Marino: Iliad, TIM, TIM maritime and Wind. A phone can attach to any of them: Iliad, TIM, TIM maritime and Wind. The order on the list is alphabetical, so the first name is not a first choice, and the list carries no speed figure.
Best at 7, 14 and 30 days
Picks at 7, 14 and 30 days in San Marino
Each length sets its unlimited tier beside one fixed tier.
| Trip length | Unlimited tier | Per day | Fixed tier | Lower price |
|---|---|---|---|---|
| 3 days | $6.84 | $2.28 | 3GB $3.20 | Fixed tier |
| 7 days | $14.78 | $2.11 | 10GB $8.56 | Fixed tier |
| 14 days | $26.88 | $1.92 | 20GB $18.08 | Fixed tier |
| 30 days | $48.96 | $1.63 | 20GB $18.08 | Fixed tier |
Tier prices are HelloRoam's catalogue prices, fetched 29 Oct 2026. Each rival prices its own tiers separately. Check that a fixed tier's validity covers your dates before you buy it. Unlimited tiers give 2GB per day at full speed.
How the picks are built
Each row reads two prices straight from the catalogue: the unlimited tier of that exact length and one fixed tier. We never multiply a day rate to make a price, and we never estimate how much data you will use. You know your own phone habits, so the verdicts say “that fits in” a volume and leave the call to you.
5 providers

Entry rate, plan shape, refund window, and support for each of the five providers this site compares. Check the San Marino coverage list before you buy.

No provider leads every column. Airalo leads on bundle reach among the counts on record, 130 destinations on one plan to HelloRoam's 127. HelloRoam and Holafly keep the refund window open 180 days. Airalo closes at 14 days. Airalo publishes support in 12 languages, ahead of every other count published on this table.
Entry rates are each provider's own cheapest published rate, not a rate specific to San Marino. Refund windows come from each provider's refund policy. Support channels and language counts come from each provider's contact page. Nothing in this table is a score we made up.
1-4 days
Quick-trip data plan
City breaks, quick holidays, long weekends.
The 3-day pick
For 3 days in San Marino that fit in 3 GB, the 3GB tier at $3.20 costs less than the 3-day unlimited tier at $6.84, with full speed for the first 2 GB each day. The smallest fixed tier is 1GB at $1.14.
Which providers fit 1-4 days
HelloRoam, Saily, Airalo, and Nomad sell fixed GB tiers, the shape a short stay uses. Holafly sells 1-day plans instead, from $3.90 for 1 day. HelloRoam lists the lowest entry rate of the five at $0.29/GB (50 GB for 7 days in Thailand). That rate covers its cheapest routes, so check the San Marino price before you count on it.

For 14 days in San Marino that fit in 20 GB, the 20GB tier at $18.08 costs less than the 14-day unlimited tier at $26.88, with full speed for the first 2 GB each day. A trip between 7 and 14 days sits between the 7-day unlimited tier at $14.78 and the 14-day tier at $26.88, each with full speed for the first 2 GB each day. No tier sits in between, so this page prices none.
HelloRoam, Saily, Airalo, and Nomad sell fixed GB tiers. Holafly sells a day rate with no GB cap. Each prices its own tiers, so compare the entry rates above before you pick a side.
Mid-trip top-up
If a fixed tier runs dry, buy a second plan. The smallest San Marino tier is 1GB at $1.14, and the existing eSIM can stay on the phone.

Every unlimited tier for San Marino
| Duration | Total price | Per day |
|---|---|---|
| 1 day | $2.40 | $2.40 |
| 3 days | $6.84 | $2.28 |
| 7 days | $14.78 | $2.11 |
| 14 days | $26.88 | $1.92 |
| 30 days | $48.96 | $1.63 |
Full speed up to 2GB per day. After that a fair-use limit slows the line.
Refund window and support on a long booking
Long stays get booked early, and dates move. HelloRoam and Holafly hold the refund window open 180 days on unused plans. Airalo closes at 14 days, so a plan bought two months before departure is past its window before the trip starts. An eSIM that fails on arrival needs a channel that is open. HelloRoam and Holafly list round-the-clock support. HelloRoam's support replies in your own language and Holafly's runs in 10 languages.

Who sells a multi-country plan
HelloRoam's largest multi-country plan covers 127 destinations on one eSIM and Airalo's covers 130. Saily, Nomad, and Holafly also sell regional or global plans, with no destination count on record here. Crossing three or more borders on single-country plans means buying a separate plan in each country and switching profiles at each one, so check that every stop sits on one plan before you buy.

FAQ
San Marino trip planning questions
Q1Which eSIM plan fits a weekend trip to San Marino?
Planning a weekend in San Marino? On TIM's 5G network, a light user burns about 1.5GB in 3 days, and the 3GB at $3.20 covers that. A moderate user using social media and navigation needs 4 to 5GB, so go with the 5GB at $4.78. Heavy users streaming or video-calling need 10GB or more; buy the largest fixed plan available. For a typical weekend traveler, the 5GB at $4.78 fits most weekend travelers without overpaying for unused data.
Q2How does eSIM cost change for 7 vs 14 vs 30 days in San Marino?
Your per-day eSIM spend in San Marino shrinks as your trip gets longer. 7 days: 20GB plan at $18.08 total ($2.58/day). 14 days: 20GB plan at $18.08 total ($1.29/day). 30 days: unlimited at $1.63/day (32% off base rate), with full speed for the first 2 GB each day. The 14-day bracket balances daily rate and flexibility for most travelers visiting San Marino.
Q3Can I top up or extend my eSIM mid-trip in San Marino?
Yes, all five providers support in-app data top-ups for San Marino. Airalo lets you buy additional data through the app in real time, and the top-up lands on the eSIM profile already installed. Unlimited plans are also sold by the day: the 1-day San Marino plan in the plan table costs $2.40, with full speed for the first 2 GB each day. Saily and Nomad both support fixed-data top-ups with no reinstallation. A top-up of 1GB costs $1.14, the same as buying a new plan. Buying a larger plan upfront is cheaper per GB than topping up, but the option is always available if you underestimate your usage.
Q4Does eSIM work in San Marino?
Yes, eSIMs work in San Marino. The network section on this page lists the local operators for San Marino; the list does not say which one a phone joins. eSIM support is built into all iPhone XS and later, Google Pixel 3 and later, and Samsung Galaxy S20 and later models. Check that your device is carrier-unlocked before purchase, then activate the eSIM profile before your flight boards to avoid airport connection delays.
Q5Does unused San Marino eSIM data roll over to the next trip?
No. Your San Marino eSIM data resets to zero when the plan period ends. There is no rollover to a future trip or a new purchase. Buy a plan that matches your actual trip length, not a larger buffer. The 20 GB San Marino plan at $18.08 lasts 30 days from activation; data left when it ends does not carry over. If you change plans before installing, HelloRoam refunds an unactivated eSIM for 180 days, the same window Holafly gives unused plans, against 14 days at Airalo.
Q6Can I use a San Marino eSIM across multiple European countries on one trip?
An eSIM bought for San Marino works inside San Marino's borders and nowhere else. For multi-country European trips, HelloRoam sells one Europe plan covering 33 areas, with 7 days of unlimited data at 3GB a day at full speed for $23.53 (catalogue checked 29 Oct 2026). Airalo's Eurolink bundle cost $31 for 10GB over 30 days (read 30 Oct 2026). Each plan covers its own country list. If San Marino is your only stop, a single-country plan is cheaper: 20GB at $18.08 for a 7-day trip. EU roaming rules do not apply to travel eSIMs because each plan is a standalone purchase.
Q7Does my San Marino eSIM stay active when I cross into a neighboring country?
No, a single-country San Marino eSIM deactivates outside San Marino's borders. Plan your data use for the exact days you are in San Marino. For trips combining San Marino with other European stops, a regional bundle covers the full itinerary on one purchase. A 20GB plan at $18.08 fits a two-week San Marino stay, but it stops working the moment you cross the border.
Q8Is a 7-day or 14-day San Marino eSIM plan better value?
The per-day data cost drops as you move up the San Marino plan ladder. A 7-day stay fits the 20GB plan at $18.08 ($2.58/day). A 14-day stay fits the 20GB plan at $18.08 ($1.29/day). Buying one correctly-sized plan costs less than buying two smaller plans back-to-back.
Q9What 5G coverage can I expect on a full San Marino itinerary?
The network section on this page lists the local operators for San Marino; the list does not say which one a phone joins. 3 of the 4 operators on that list carry a 5G label. A 5G label on that list is a technology label, not a speed. For a full-country itinerary, check the operator list before finalizing your plan.
Q10Should I get a fixed data plan or unlimited for a San Marino trip?
Fixed data plans fit trips under 7 days in San Marino. At 1.5GB/day the 20GB plan at $18.08 covers a 7-day trip with data to spare. Unlimited for 7 days costs $14.78, with full speed for the first 2 GB each day, which is comparable to a fixed plan. Switch to unlimited if you stream video daily, work remotely, or use navigation continuously. A 14-day unlimited plan costs $26.88 ($1.92/day), with full speed for the first 2 GB each day.
