The cheapest provider changes based on how long you stay. Work through these steps to land on the right plan without over-paying.
- 1 · Pick your trip lengthUse the 7 / 14 / 30 day tabs in the comparison table below. Each tab re-ranks providers by estimated cost for that duration, so the top row is the most affordable match for your travel window.
- 2 · Choose fixed or unlimitedShort stays (under 7 days) almost always favor a fixed-data plan. At 14+ days, unlimited daily rates can undercut fixed plans if you stream video. The table shows both side by side at your selected duration.
- 3 · Install before you flyPurchase on the provider's official site, scan the QR code at home on Wi-Fi, and add the eSIM as a second line. Your home SIM stays active throughout.
- 4 · Activate on arrival in San MarinoSwitch your data line to the travel eSIM when you land. Most plans start counting data only from first connection, not from purchase, so you don't lose a day in transit.

Full Nomad review→San Marino What to know before you go
A weekend in San Marino (3 days) needs about 5GB. A 5GB plan costs $4.78, which works out to $1.59/day. Extend to a 7-day trip and the 20GB plan at $18.08 ($2.58/day) becomes the better fit. Compare plans by your exact travel dates to avoid paying for unused data.

For 30-day stays (digital nomads, study abroad), unlimited at $1.97/day on a monthly plan drops to $59.04/month. Fixed 20GB at $18.08 covers 13 days of moderate use.

San Marino eSIM FAQ
Frequently asked questions
Which 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.
How 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 $1.97/day (18% off base rate). The 14-day bracket balances daily rate and flexibility for most travelers visiting San Marino.
Can I top up or extend my eSIM mid-trip in San Marino?+
Yes, all four 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 activates within 60 seconds. Holafly extends your unlimited plan by adding days from the app. Adding one day costs $2.40. 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.
Does eSIM work in San Marino?+
Yes, eSIMs work in San Marino on TIM and Wind. Coverage operates at 5G. 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.
Does 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. A 7-day San Marino plan like the 20GB tier at $18.08 expires after 7 days whether you use all 20GB or not. If your trip ends early, most providers (Airalo and Holafly) offer refund policies on unused plans within their support window.
Can 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, Airalo's Eurolink bundle covers 39 EU countries on a single plan with no swapping required at each border. 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.
Does 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.
Is 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.
What 5G coverage can I expect on a full San Marino itinerary?+
San Marino eSIMs run on TIM and Wind, TIM maritime at 5G. Coverage holds reliably in tourist areas and city centers. For a full-country itinerary, check the detailed network map before finalizing your carrier preference.
Should 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 $15.46, 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 $29.90 ($2.14/day).
