Lugano and Lake Como: Roaming Between Switzerland and Italy (2026)

Ticino, Switzerland's Italian-speaking canton, and the Italian lakes can feel like one region, with the same language and trains between Milan and Lugano. For your phone they are two countries: Lugano and Locarno are in Switzerland, outside the EU's Roam Like at Home area, while Como is in Italy, inside it.

This guide explains roaming between Switzerland and Italy around Lugano and Lake Como: the border trap, the lakes, the train from Milan and one plan for both.

Key facts for Lugano and Lake Como

EU roaming: Italy is covered by Roam Like at Home; Switzerland is not
Border trap: near the border and on the lakes, a phone can connect to the other country's network
One plan for both: the Europe plan covers Switzerland and Italy; a Switzerland plan works only in Switzerland
Emergency numbers: 112 on both sides; police 117 in Switzerland and 113 in Italy
Embassies: mostly in Bern for Switzerland and in Rome for Italy

Lugano and Lake Como: two countries, two roaming rules

Lugano and Locarno are in Ticino, and Chiasso, on the Swiss side, borders Como. Como and the Italian shores of Lake Maggiore and Lake Lugano are in Italy. On an EU SIM, Italian networks are billed as at home and Swiss ones as roaming outside the EU: some operators include Switzerland, many charge for it.

Visitors with a SIM from outside the Roam Like at Home area usually pay roaming on both sides unless their tariff includes them. A Telcomia Switzerland plan works only in Switzerland, so in Como or Milan it gives no data on Italian networks.

The border trap around Chiasso, Como and the lakes

Near a border, a phone can connect to the strongest signal, even one from the neighbouring country. Around Lake Como, Lake Maggiore and the valleys near Lugano, a phone on the Italian side can pick up a Swiss network, and in Ticino near the border it can pick up an Italian one. Lake Lugano and Lake Maggiore have Swiss and Italian shores, so the same can happen on a boat.

Set network selection to manual in your phone's mobile settings, pick a network of the country you are in and check its name before you use data. With the Europe plan, a switch between Swiss and Italian networks stays within the plan.

The train from Milan

Trains link Milan and Lugano, and on the way the phone can move from Italian to Swiss networks. If you use your EU SIM for data in Milan, switch mobile data to an eSIM that covers Switzerland and turn data roaming off on your home line before the train reaches the border.

Which plan fits your trip

If your trip crosses the border, the Europe plan covers Switzerland and Italy on one eSIM, among 38 destinations. A Switzerland plan suits a stay in Switzerland, and an Italy plan suits visitors from outside the Roam Like at Home area who stay on the Italian side.

With an EU SIM you are already covered in Italy, so the gap is Switzerland. Standard plans are data only, with calls through apps such as WhatsApp; the plan details show the Activation line, which gives the start of the validity period, plus the duration, the data and whether you may share the connection.

Before you leave

Install the eSIM at home on Wi-Fi and set it as your line for mobile data.
Turn data roaming on for the eSIM and off for your home line.
Find manual network selection in your phone's settings.
Check whether your home tariff includes Switzerland.
Download train tickets and offline maps before boarding.

Consular protection: one 112, different local numbers

112 works in Switzerland and Italy. In Switzerland, 117 is the police, 118 the fire service and 144 an ambulance.
In Italy, the older numbers 113 (police), 115 (fire) and 118 (medical) also work, so 118 means a different service on each side of the border.
Embassies are mostly in Bern and Rome, and many countries have consulates in Zurich, Geneva and Milan. The Telcomia app shows which mission is responsible for you, with address and phone.
If you are an EU citizen and your country has no embassy or consulate in Switzerland, the embassy of any other EU country must help you on the same terms as its own nationals (Article 23 of the Treaty on the Functioning of the EU).
The app keeps key emergency phrases in Italian ready to show on screen.

Questions travellers ask about Lugano and Lake Como

Does EU roaming work in Lugano?

Not by law. Lugano is in Switzerland, outside Roam Like at Home, so it depends on your operator: some include Switzerland, many charge roaming. In Como and the rest of Italy, an EU SIM on an Italian network works as at home.

Will an Italy plan work in Switzerland?

A Telcomia Italy plan is for Italy; for Lugano or Locarno as well, choose the Europe plan, which covers both countries. An Italian operator's SIM pays roaming in Switzerland unless its tariff includes it.

Why does my phone switch networks around Lake Lugano?

Lake Lugano has Swiss and Italian shores, so a phone can join either country's network. Choose the network of the country you are in manually, or use the Europe plan, which covers both.

Which emergency numbers should I save?

112, which works on both sides. Add 117 for the Swiss police and 144 for a Swiss ambulance; in Italy, 113 is the police and 118 is for medical emergencies.

The short version

Lugano and Locarno are in Switzerland, outside EU roaming, and Como is in Italy, inside it, with networks overlapping near the border and on the lakes. Check the network name, remember that a Switzerland plan works only in Switzerland, and use the Europe plan for both countries on one eSIM.
