Phone, mobile data and Wi-Fi at Lake Como

Who needs what

EU, Iceland, Liechtenstein, Norway

Nothing to buy. Under “Roam like at home”, calls, texts and data in Italy cost what they cost at home. Your operator may apply a fair-use limit on data, and if over four months you roam more than you use your phone at home, it can ask you why. Source

United Kingdom

EU roaming rules don't apply to UK SIMs. On 31 October 2026 the networks' own pages said: Vodafone £2.75 a day (or an 8-day pass for £16), EE £2.72 a day (7-day pass £16.50), Three £2.75 a day for customers since 18 December 2025 (£2 for older plans), and O2 includes Europe up to 25 GB. Check your own plan before you go. Source

United States

US plans charge per day you use the phone abroad: Verizon TravelPass is $12 a day per line, and AT&T's International Day Pass is also $12 a day for the first line. T-Mobile includes basic data abroad on many plans and sells passes for faster data; check its current prices. For a stay of more than a few days, a travel eSIM is usually the cheaper way to get data.

Switzerland

Swiss SIMs are outside EU roaming, so it depends on your contract. Swisscom says its blue Mobile plans include roaming data and, since June 2025, data in neighbouring countries as at home; Salt's Europe plans include Italy. Swiss operators make you set a roaming cost limit. Source

Prices as the operators published them on 31 October 2026; they change, so check yours. Sources: Vodafone UK, EE, Three, O2, Verizon, AT&T, Salt (links at the bottom of the page).

Swiss networks near the border

Switzerland is not part of EU roaming. A phone with an EU SIM that connects to a Swiss network is billed at its operator's Swiss rates, which can be expensive. Germany's consumer advice centre reports bills of €59.50 and about €110 from phones that joined Swiss networks near the border.

Around Como this has been documented. In 2020, La Provincia di Como and Corriere del Ticino reported residents' phones joining a Swiss network, shown as “Sunrise Swiss”. The places named were the Como districts of Garzola, Sagnino and Monte Olimpino, and Brunate, Lipomo, Gironico and Montorfano. People were charged roaming. Swisscom called it “unintentional roaming” and said it has no detailed border coordination with Italy. It also happens the other way: in Lugano, Swiss phones regularly join TIM and Vodafone Italy. We found no report naming a lakeside town further up the lake, so we don't name any.

Turn off data roaming (iPhone)

Settings → Mobile Data (Cellular) → Mobile Data Options → Data Roaming off. With a SIM from another country, every network in Italy counts as roaming, so this stops mobile data altogether: use it near the border when you can do without data for a while. Source

Pick an Italian network by hand

If your phone offers it, switch automatic network selection off and choose an Italian network (TIM, Vodafone, WindTre or Iliad). iPhone: Settings → Mobile Service → Network Selection. Android: Settings → Network & internet → SIMs → Network. Turn automatic selection back on when you leave the border area, or your phone may not find a network elsewhere. Source

Check your plan for Switzerland

Some plans include Switzerland (O2 UK lists it in its Europe zone, for example). If yours does, joining a Swiss network costs nothing extra; if it doesn't, the two steps above are what protect you. Germany's consumer advice centre gives the same advice: manual network selection, data roaming off or airplane mode near the border. Source

Italian networks and where to check coverage

Italy has four mobile networks: TIM, Vodafone (part of Fastweb since January 2026), WindTre and Iliad. Each publishes a coverage map, and the communications regulator AGCOM publishes its own Broadband Map. All of these show declared coverage: what the operators say they cover, not measured signal. AGCOM itself warns that real performance can differ significantly. We haven't measured the signal around the lake ourselves, so we don't name weak spots.

Wi-Fi

On the ferries

Navigazione Laghi doesn't advertise Wi-Fi on board: not in its Lake Como FAQ, not on any of its boat pages. Plan on mobile data, and download the timetable before you board. Source

In town

We couldn't confirm any current free municipal Wi-Fi in Como, Bellagio, Menaggio, Varenna, Lecco, Cernobbio or Tremezzina. Como's 2013 free Wi-Fi page no longer exists. Cafés and hotels are where you'll find Wi-Fi. Source

Library in Como

The Biblioteca comunale “Paolo Borsellino” has internet terminals you can use on request at the desk. Its page doesn't mention Wi-Fi. Source

No ID needed

Since 2013, Italian law has said that offering public Wi-Fi doesn't require identifying the user. Source

Travel eSIM or Italian SIM

Your phone

A travel eSIM on an iPhone needs an XS, XR or later that isn't locked to a carrier: Settings → General → About should say “No SIM restrictions” next to Carrier Lock. If you keep your home line switched on, the eSIM carries the data but your home line can still be charged roaming for calls and texts. Source

Which network an eSIM uses

Travel eSIMs ride one or two Italian networks, not all four. On their own pages (31 October 2026): Airalo names WindTre plus one other, Holafly names Vodafone and WindTre, Ubigi names Iliad and WindTre. None of them named TIM. Compare with the coverage maps above for the places you'll stay. Source

An Italian SIM

Buying a SIM in a shop means showing an ID document; Fastweb's own guide also lists the codice fiscale, Italy's tax code. Take your passport and ask in the shop what else they need. Source
