eSIM for Italy: The Number a Data Plan Cannot Sell

Italy is the market where the distance between what travellers search for and what a travel eSIM sells is widest. Two phrasings of one question, data and voice, and data and phone, carry 880 searches each. Together they are the largest cluster of Italy queries on this list that is not about price, and no product sold into Italy answers them.

The reason is structural rather than commercial. A travel eSIM is a data subscription provisioned by a company outside the country, riding an Italian network under a wholesale arrangement while carrying no Italian number. Calls over data work. A call to a hotel reception, a taxi dispatch or a restaurant that takes bookings by phone does not, because that call needs a line with a number attached at one end.

This page prices the 204 Italy plans ten brands sell, recomputed from the plan files on 24 October 2026, and it prices the alternative too, because the 1760 searches want a different product.

The 1760 searches asking for a number nobody sells

Read the two queries together and the intent is plain. People are not asking whether Italy has good data coverage. They are asking whether a plan exists that keeps a phone number working for calls and for codes that arrive by text. The question is asked on a forum because the product pages answer something else.

The answer splits by what the call is for. Codes and messages from Italian services are addressed to an Italian number and arrive wherever that number lives, so a home line left switched on receives them at whatever the home carrier charges for roaming. Calls to Italian businesses need a number that a landline can dial. Nothing installed from abroad provides one.

That leaves exactly one route to an Italian number, and it is the route the market has spent a decade telling travellers is closed.

Where an Italian number still comes from

TIM, Vodafone, WINDTRE and iliad own the masts, and all four sell prepaid lines to visitors. The legal part is a document check, not a residency test. Article 98-undetricies of the Italian communications code requires the operator to identify the buyer and keep a copy of the document before the line is activated, and since the April 2025 security decree it names the passport explicitly for anyone outside the European Union.

The tax code is the part most guides get wrong. The codice fiscale is the field Italian billing systems are built around, and it is what operators ask for on standard plans. The visitor bundles are designed around a passport instead, and a carrier store can generate a code from the passport at the counter. So the counter is not closed. It is slow, and it only exists inside shop hours.

Two operator products matter here. TIM sells its visitor line at the counter as a plastic SIM rather than a profile. Vodafone sells prepaid as an eSIM, issued in a store as a QR card or by email as a link, and either route runs against an identity document and the tax code. Neither is a product a visitor finishes from a sofa the night before the flight without producing a document.

The price is the part that decides it. TIM’s visitor line runs EUR 24.99 for thirty days once the SIM fee is added. Roamic sells 10GB for thirty days at $6.00 and Ubigi sells 20GB for thirty days at $9.00, so the Italian line costs roughly four times what 10GB of data costs and the difference buys a number plus domestic calls plus European roaming on the same line. Whether that is worth it turns on one question. If a phone has to ring, it is. If the trip needs maps, tickets and messages, the number buys a service nobody will use.

Which of the four networks carries the plan

Italy has four network operators and this comparison contains three of them. TIM, Vodafone and WINDTRE appear on all ten brands, in the same order, with no exceptions in the plan files. iliad, the fourth operator, appears on none of them.

That makes the brand question a price question. There is no plan in this market that can be chosen for its network, because no brand sells a single-network product. The GSMA specification behind the format was written to detach a subscription from a plastic card, not to hand a reseller a radio network of its own, so the seller and the mast are two different companies by design. A traveller who has read that TIM holds the low band that survives mountain valleys cannot buy TIM through a travel eSIM. The route to a specific network is a local prepaid line, which is the same counter visit the section above prices.

The practical consequence is that a slow connection in a Dolomites valley is not a brand failure. Every plan in this comparison is choosing between the same three networks by the same rules, and the phone picks the cell. The network breakdown for Italy shows how the three differ, and the differences are real but not selectable at checkout.

What each size costs on this shelf

The shelf runs from $0.51 to $83.00, which is a ratio of 163 to one, and most of that spread is the difference between a 500MB test purchase and a month of unlimited data rather than between two sellers. Per gigabyte, the metered plans run from $0.32 to $4.50 with a median of $1.35.

Each row takes the cheapest plan that brand sells at that allowance, so the table compares ten sellers rather than every window each one lists. Two rows are ties worth naming. At 5GB, Ubigi and Roamic both charge $4.00, and Ubigi gives thirty days against Roamic’s twenty-one.

Roamic holds the cheapest price in six of the seven rows, one of them shared with Ubigi, and Ubigi holds 20GB outright. That $9.00 for thirty days is where the shelf stops making sense.

Where the shelf prices itself backwards

A ladder of sizes is supposed to cost more as the allowance grows. Three rungs at Ubigi break that rule, and the breaks are visible without a calculator.

Twenty gigabytes for thirty days costs $9.00. Ten gigabytes for thirty days costs $12.00. The larger plan is three dollars cheaper than the smaller one at the same window, and it is the same at eight days, where 10GB also costs $9.00.

Two rungs lower the inversion repeats. Three gigabytes for thirty days costs $5.00 and five gigabytes for thirty days costs $4.00, so the smaller bucket is the dearer one.

The annual plans show the same pattern in a different place. 24GB across 365 days costs $12.00, which is $0.50 a gigabyte. 60GB across 365 days costs $33.00, which is $0.55. The bigger annual plan is the worse annual plan. Only the 240GB year at $77.00, at $0.32 a gigabyte, beats either of them, and it is the lowest rate in the entire Italian market.

Sizes and windows are priced by hand here, and assuming a bigger number is a better buy leads to an overpayment nobody notices.

What the brands travellers search for charge

Airalo and Saily are the two brands searched for by name most often in this market, and both sit above the floor by a wide margin.

Airalo sells 18 Italy plans from $4.00 to $64.00 and reaches $0.70 a gigabyte at its best, which is 50GB for $35.00. Its 10GB month is $19.00 against Roamic’s $6.00, and its 5GB week is $10.00 against $4.00. The product is the same three networks and the same data profile.

Saily sells 11 plans and holds the dearest price at two sizes, $20.99 for 10GB and $28.99 for 20GB. Its 10GB costs 3.5 times Roamic’s and buys nothing extra in return, which makes it the clearest example in this market of a name being the whole premium.

Holafly sells nothing but unlimited, six plans from $11.90 for three days to $64.50 for thirty, and publishes no daily threshold at all. Its thirty-day price is more than double Roamic’s $30.00 for a product with no stated full-speed allowance.

What a week in Rome and Florence draws down

Three gigabytes covers a week of city travel. That is maps on foot, train times between cities, restaurant searches, messages and a few hundred photo uploads, and it leaves room.

Four things move the number, and only one of them is video.

A rental car. Live traffic on a screen burns about 100MB an hour, so a week driving through Tuscany adds two to three gigabytes by itself. Central Rome and Florence are cut into camera-enforced limited-traffic zones, and a navigation app working from a stale map is how a hire car collects fines worth many times the plan.

A rail route across three cities. Photos sent home from a hotel are the upload; photos sent from a train are the upload plus a weak signal plus a retry. Three cities with video lands near 8GB.

A second phone on the same connection. Two people tethered to one profile double the figure, and it is the most common mistake in the market because the fix costs $6.00.

A laptop. An afternoon of remote work over a hotspot can match a week of phone use, and it hits an unlimited plan harder than a metered one because the daily threshold arrives inside two hours of video calls.

The pricing makes the decision easy. 5GB costs $4.00 and 10GB costs $6.00, so doubling the allowance costs 50% more. Buying 3GB to save two dollars is the only choice on this shelf that reliably costs more later, and the trip-length board prices each stay length against the plans that actually fit it.

Does the plan survive Switzerland and the UK

An Italy-only plan ends at the border, in both directions, and the border that catches people is the northern one.

France, Austria and Slovenia sit inside the European roaming area and appear on almost every European list. Switzerland does not, for the same reason Norway and the Balkan states sit outside parts of it. The EU roaming rules attach to a European subscriber’s line and say nothing about a reseller’s data profile, which is why the border is decided by the seller’s country list rather than by regulation. The Milan to Zurich train loses its connection in the tunnels before the border check, and a bundle that names France and Austria routinely leaves Switzerland out. That leg needs a second product, and the Switzerland table prices it at $7.00 for 10GB over thirty days, or $4.00 for 5GB.

The United Kingdom is the pairing this market searches for by name, and it is a different calculation because Brexit took the UK out of the roaming arrangement rather than out of Europe.

Two country plans are cheap here, cheaper than most travellers expect. Italy at 10GB for thirty days costs $6.00 on Roamic. The UK at 5GB for twenty-one days costs $4.00 on the same brand. The two-country bill is $10.00 for 15GB, and that is the number a regional bundle has to beat.

The single-country alternative is uncomfortable for the bundle. Italy alone at 20GB for thirty days costs $11.00 on Roamic and $9.00 on Ubigi. So the two-plan route costs one dollar more than Ubigi’s Italy-only 20GB and delivers a second country. Shorten the UK leg to a three-day stop and the UK plan falls to $3.00 at 3GB, which puts the total at $9.00, exactly what Italy alone costs at 20GB.

The conclusion is narrow but usable. A two-country trip on this route is cheaper as two plans than as one bundle unless the bundle lands under $10.00. A three-country route changes the arithmetic, because the third plan adds another $4.00 to $6.00 and a bundle that names all three starts to have room. The Europe coverage list shows which products name which countries, and the UK guide prices the second half on its own.

The two smaller cases sit inside the same question. The Vatican is 44 hectares inside Rome and the Italian networks reach it, so a plan that names Italy only works in St Peter’s Square. San Marino is the one that surprises people. It runs its own network, sits outside the European roaming area, and the drive up from Rimini is short enough that a profile stops registering before anyone thinks to check.

What unlimited stops at

101 of the 204 Italy plans are flat-rate rather than metered, which is 49.5%, and the flat-rate shelf is built for short trips. Nine of those 101 run a full thirty days, and 13 run 28 days or longer.

What separates two unlimited plans at the same window is the number the checkout does not show, which is the daily full-speed allowance and the speed the connection falls back to.

Roamic prints 3GB a day and 1Mbps after it on every unlimited plan, the clearest threshold here. Saily prints 5GB a day and 1Mbps, Jetpac 3GB and 1Mbps, Nomad 2GB. Ubigi publishes a different figure on each plan, and its thirty-day Italy plan states 5GB a day with a 2Mbps fallback, the fastest here. aloSIM publishes a range rather than a number. Holafly publishes none.

Against the thirty-day prices the shelf reorders. Roamic charges $30.00 for 3GB a day at 1Mbps. Ubigi charges $39.00 for 5GB a day at 2Mbps. Airalo charges $64.00 for the same 5GB a day and a slower fallback, Holafly $64.50 for a plan with no published figure, and Jetpac $83.00 for 3GB a day. The $25.00 gap between Ubigi and Airalo buys a slower fallback and no extra data.

A metered bucket avoids the question, because it does not slow down. It runs out, visibly, on a known date. The fair-use table carries the published threshold for every unlimited plan in this market.

Is a year of Italian data worth holding

For one trip, no. For a second trip inside twelve months, the arithmetic changes completely, because Italy is unusually cheap on long validity.

Ubigi sells 24GB across 365 days for $12.00. That is $0.50 a gigabyte and $0.03 a day, and it costs twice what ten gigabytes costs for a month. A traveller who flies to Italy in spring and again in autumn spends $12.00 once and keeps a live profile between the trips, which is the one case where a plan’s expiry date is an advantage rather than a risk.

The 240GB annual plan at $77.00 is a different product for a different buyer. At $0.32 a gigabyte it is the cheapest data in this market by a margin, and no holiday will use a tenth of it. It suits a second home, a long project or a phone used as a hotspot for a season.

The trap is the middle. 60GB across a year at $33.00 is $0.55 a gigabyte, worse than the 24GB plan and nearly three times its price. Three sizes, three rates, and the cheapest rate per gigabyte is not on the biggest plan. It is the same inverted ladder the metered shelf shows.

Setting it up before the flight

Buy it from the seller’s app or site a day or two before departure, on wifi, with the home number still live. The 3-D Secure step is where purchases stall. A card enrolled in the scheme texts six digits to the number on file, and that number is usually the SIM in the physical tray, so a purchase started after the tray is emptied cannot be finished. Buy first, then swap.

Three settings decide whether the phone works on landing. Name the travel line, because two profiles with the same label is the most common reason people switch on the wrong one. Point mobile data at the travel line and leave the home line for calls and texts. Turn data roaming on for the travel line, since a travel eSIM counts as roaming on the network it joins, and leave it off on the home line so airline and bank messages arrive without a data bill.

The physical details are settled before the plane lands. Fiumicino is 30km from the centre and the Leonardo Express covers it in 32 minutes to Termini, so a phone that is already on a network skips the counter queue entirely. Airport wifi in Italy asks for an email or a code and caps the session, which is fine for a message and useless for a map. Emergency calls are the exception to everything above, because 112 works on any network the phone can see with or without a plan.

One rule survives every troubleshooting guide. Do not delete the profile to fix a problem. A deleted eSIM cannot be restored from the handset, and the usual repair is buying a second plan. The installation walkthrough covers the QR route and the manual route for a phone that will not scan, and the compatibility check settles the handset question before money changes hands.

Who answers when the profile dies in Rome

Not the carrier. A prepaid line bought at a TIM or Vodafone counter comes with a counter, and the operator can reissue it, explain a dead service or replace a card. A travel eSIM is a wholesale product on the same radio network, and no Italian operator holds a record of it, so the only support that can touch the profile is the seller’s, from another time zone.

That changes what to have ready before writing in. The order reference, the address the QR code went to, the handset model and the exact step the connection fails at. Most desks open by asking for a reinstall, a reinstall means deleting the profile, and deleting it before the order number is in hand destroys the only proof that a purchase exists.

Two failures look like seller faults and are not. A handset still locked to a home carrier refuses the profile outright, and a phone without the Italian 5G or low bands will hold a signal in Rome and lose it in the Apennines. Both are settled before the flight.

What the counter in Italy really sells is somebody to stand in front of, in the same time zone, holding a replacement card. That is worth EUR 24.99 to a traveller whose phone must work and is wasted on one whose data plan already does. The comparison table prices the alternative for anyone still deciding.
