eSIMs for San Marino and Vatican City – Why Your Italy Plan Does Not Cover Them
eSIMs for San Marino and Vatican City — Why Your Italy Plan Does Not Cover Them
Updated August 2026 · Prices in USD, verified at checkout · Coverage data from our supplier’s live catalogue
Both of these countries sit entirely inside Italy. Both are served by Italian mobile operators. And neither of them is covered by an Italy eSIM — or by our 41-country Europe plan. That is genuinely counter-intuitive, it is the kind of thing people discover at the worst moment, and it is the reason this article exists.
The finding, before anything else
We checked our supplier’s live catalogue. The Italy plan lists exactly one covered territory: Italy. The Europe 41-country plan lists forty-one countries and San Marino and Vatican City are not among them. Both micro-states are separate telecom territories with their own country codes, and both are sold as separate plans. If you want guaranteed data inside either one, that is the plan you need.
Which networks they actually use
Here is the part that makes it confusing. Both San Marino and Vatican City are served by TIM (5G), Wind (5G) and Iliad (5G) — Italian operators, the same names you see on an Italian trip. The radio masts are Italian. What differs is the network identity your phone registers against, and roaming agreements are written against that, not against geography.
So your phone can be standing forty metres from a Roman street, seeing a TIM mast, and still be told by the network that it is somewhere your plan does not cover.
What this means in practice — the two cases are different
Vatican City: usually a non-event
The Vatican is forty-four hectares, entirely surrounded by Rome, and much of St Peter’s Square and the museum queue is within easy reach of Italian cells that never hand you over at all. Most visitors on an Italy plan spend a morning there and notice nothing.
We are not going to turn that into a promise. Handover behaviour depends on where you stand, which mast is strongest and how the networks are configured on the day. If you are visiting the Vatican as part of a Rome holiday, carry your Italy plan and expect it to be fine — and know that the Vatican plan exists if you want certainty rather than probability.
San Marino: a real separation
San Marino is different in kind. It is a proper country of sixty-one square kilometres on a mountain, an hour inland from Rimini, and you reach it by driving up a road with a border on it. Up there you are comfortably inside San Marino’s own network coverage, not incidentally catching an Italian cell across a piazza.
If you are doing the classic Rimini beach holiday with a day trip to San Marino, an Italy plan may well leave you without data for the day — exactly when you want maps for the old town and the three towers. The San Marino plan costs $3.90 for 3 GB, which is less than the parking.
What both plans cost
| Plan | 3 GB | 5 GB | 10 GB | Unlimited, 1 day |
|---|---|---|---|---|
| San Marino | $3.90 | $4.90 | $8.90 | $4.30 |
| Vatican City | $3.90 | $4.90 | $8.90 | $4.30 |
| Italy (for comparison) | $3.90 | $4.90 | $8.90 | $4.30 |
All three are priced identically, all run for 30 days, and all ride the same Italian networks. Unlimited on either micro-state runs $28.31 for a week or $91.63 for 30 days — $3.05 a day — though it is hard to imagine needing thirty days of unlimited data in a country you can walk across.
The fair-use number, stated openly
San Marino and Vatican City Unlimited allows 5 GB per day at full speed, then continues at 512 Kbps until the next day resets. Five gigabytes is a heavy travel day — maps, messaging, social media and a few videos rarely come close. At the reduced speed maps, messaging, tickets and email still work; HD video does not.
The practical recommendation
Rome trip including the Vatican: buy the Italy plan. It is what you need for the other six days anyway, and the Vatican is small enough that it very rarely matters.
Rimini or Bologna trip including San Marino: buy the Italy plan for the trip and add the 3 GB San Marino plan at $3.90 for the day up the mountain. Two profiles, four dollars, no thinking required.
Staying in San Marino: buy the San Marino plan properly. People do stay — it has hotels and a genuinely good old town — and in that case it is the primary plan, not the add-on.
Interrailing across Europe: note that the Europe 41-country plan does not include either. If your route touches them, add the specific plan.

Like most travel eSIMs, this one is home-routed. Your phone attaches to a mast in San Marino or Vatican City, but your traffic reaches the public internet through a gateway in France or the Netherlands. Websites see a European address, so anything geo-locked to Italian services may object. Latency is a little higher; maps, messaging, browsing and video calls are unaffected. Our transparency report lists the exit region for every destination we sell.
Frequently asked
Does my Italy eSIM work in Vatican City?
Often, in practice — the Vatican is 44 hectares inside Rome and Italian cells reach much of it. But the Vatican is a separate telecom territory and our Italy plan does not formally cover it, so we cannot promise it.
Does my Italy eSIM work in San Marino?
Do not count on it. San Marino is a genuine country an hour inland with its own network identity — this is a real separation, not a technicality.
Does the Europe 41-country plan cover them?
No. We checked the live country list: neither San Marino nor Vatican City appears on it.
Which networks do they use?
TIM, Wind and Iliad — all Italian operators, all with 5G. The masts are Italian; the network identity is not.
What should I buy for a Rome trip with a Vatican visit?
The Italy plan. Add the Vatican plan only if you want certainty rather than probability.
What should I buy for a Rimini trip with a San Marino day?
The Italy plan for the trip, plus 3 GB of San Marino at $3.90 for the day. It costs less than lunch.
Can I hotspot my laptop?
Yes — tethering is included on both plan types at no extra charge.
When does my plan start?
On first connection to a network in that territory, not at purchase. The unused QR code stays valid for 180 days.
Two small countries, one small precaution
Neither of these is a reason to worry about a trip. Both are a reason to spend four dollars before one, so that the day you climb the mountain or queue for the Sistine Chapel is not the day your maps stop working.
