Vodafone Roaming Passport
Vodafone shows the San Marino roaming rate as £6/day, but the total depends on how many days your phone touches TIM's network — including transit days where you land at midnight. An eSIM at $0.86/GB charges a fixed amount regardless of activation timing.

EE's £6/day pass in San Marino uses TIM's network — identical to what a travel eSIM from $0.86/GB delivers.
AT&T International Day Pass
AT&T's day pass covers data and calls to the US. Texts to local San Marino numbers are billed separately at $0.25-$0.50 per SMS in some plan tiers. Verify before sending local contact messages abroad.
Verizon TravelPass
In San Marino, Verizon connects to TIM towers at $10/day. An eSIM reaches the same towers from $0.86/GB.

Real savings scenarios for San Marino
Solo traveler
Break-even point for a solo San Marino trip: day one. AT&T charges $10 on the first calendar day. A 20GB eSIM at $18.08 is already cheaper than two AT&T days. By day 10, the eSIM has saved $81.92 total. There is no trip length at which AT&T roaming costs less than a travel eSIM for San Marino.
Family trip
Verizon TravelPass charges per line, not per account. A family of four pays $40/day ($10 x 4 lines). Over 10 days in San Marino: $400. Four eSIMs at $18.08 each: $72.32. Per-person savings: $81.92. All eight data connections (4 carrier, 4 eSIM) route through TIM's 5G towers.
Business trip
A 1-hour Zoom call in San Marino on AT&T pay-per-use (no plan): 450 MB at $2.05/MB = $922.50. On AT&T International Day Pass: $10 for the day, but the day pass charges even if you only took one call. On a 20GB eSIM at $18.08: 450 MB is a fraction of the plan. Business travelers average 2-3 video calls per day in San Marino. The eSIM handles all of them within the same $18.08 fixed cost.
Long-stay and digital nomads
Per-hour data cost in San Marino at different trip lengths: 5-day trip: AT&T = $0.63/waking hour, eSIM = $0.11/waking hour. 14-day trip: AT&T = $0.63/waking hour, eSIM = $0.08/waking hour. 30-day stay: AT&T = $0.63/waking hour, eSIM = $0.16/waking hour. (Assuming 16 waking hours/day.) AT&T's per-hour rate stays flat. The eSIM's per-hour rate drops as the plan spreads across more days.
Frequent traveler annual savings
Frequent travelers to San Marino (4 trips/year) face $400 in annual AT&T roaming charges. Four 20GB eSIMs total $72.32 for the same year. Annual savings: $327.68. All eight connections (4 AT&T, 4 eSIM) route through TIM's 5G towers.
Extended stay economics
Extended stays over 30 days open a third option: local prepaid SIMs in San Marino. Local prepaid SIMs run $10-$30/month but require in-person purchase and passport registration. A travel eSIM on TIM at $51.60 for 30 days eliminates the store visit. AT&T at $300/month is the most expensive option regardless of stay length. For stays over 60 days, a local SIM may beat the eSIM on per-GB price, but the eSIM avoids registration paperwork and works from day one.
Frequent flyer savings
AT&T roaming of $100 for 10 days in San Marino represents 3-7% of a typical international trip budget ($1,500-$3,000 for flights, hotel, food). An eSIM at $18.08 drops that line item to under 1%. Over 2 annual trips, roaming goes from $200 to $36.16. That $163.84 pays for an extra dinner and museum visit per trip.
Data usage savings
A traveler using Google Maps 3 hours/day in San Marino consumes 24 MB/day in navigation data. Over 10 days: 240 MB (0.2 GB). AT&T charges $10/day regardless of how little data you use. An eSIM at $0.86/GB on TIM charges $0.21 for navigation alone. The eSIM's per-activity cost is a fraction of the per-day fee.
Couples trip savings
A couple on AT&T traveling to San Marino for 10 days: 2 lines x $10/day x 10 = $200. Two 20GB eSIMs: $36.16. Savings: $163.84. Both partners keep their US numbers active via WiFi Calling. Each eSIM connects independently to TIM's 5G towers. No hotspot coordination required — each phone has its own data.
UK carrier comparison
UK travelers face lower daily roaming rates than US travelers: Vodafone GBP6/day vs AT&T $10/day in San Marino. But the eSIM still costs less than both. Vodafone 10-day total: GBP60. AT&T 10-day total: $100. eSIM: $18.08. The eSIM wins regardless of which home country the traveler comes from.
Our verdict
Against AT&T: $81.92 saved (82%). Against Verizon: $81.92 saved. Against T-Mobile high-speed: $131.92 saved. Against T-Mobile free tier: $0 carrier cost but 256 Kbps speed renders maps, ride-hailing, and video calls unusable. A 20GB eSIM at $18.08 delivers full 5G on TIM for less than any paid roaming option.

The same family shares one travel eSIM on TIM starting at $1.14 for 1GB — a single purchase covers all devices through tethering. Verizon charges the same per-line rate. T-Mobile includes free data at 256 Kbps, which cannot load a map.
- Is T-Mobile's free international data fast enough in San Marino?
- No. At 256 Kbps, T-Mobile's free international tier in San Marino cannot load a map tile in under 15 seconds. Video calling needs 2 Mbps minimum — eight times what T-Mobile provides for free.

- How much data does Google Maps use in San Marino?
- Google Maps uses 5-10 MB per hour of active navigation in San Marino. On AT&T pay-per-use that costs $10-20 per hour of driving.

An eSIM installs digitally via QR code before you leave home and activates the moment you land in San Marino. Both connect to the same local towers and deliver the same speeds. The eSIM advantage is convenience and cost: no counter lines, no passport copy, no risk of losing a tiny card, and prices starting at $0.86/GB versus $10-30 for airport SIM kits with less data.
