The phone exits airplane mode, connects to a foreign network and starts working again as if nothing had happened. Roaming, on the other hand, knows very well where you are. Before entrusting it with itineraries, tickets, payments and the hotel address, it is best to spend a few minutes on the settings smartphone while travelling. Better to do it at home, with Wi-Fi available and without a queue at passport control behind you.
What to check before entrusting your trip to your smartphone
Boarding passes, reservations, bank accounts, photographs, documents and directions now end up inside that small rectangle. A failed connection can leave the traveler without a map; one who starts too well can present him with the bill. Between telephone plan, offline maps and device location, these are the five checks to do before closing your suitcase.
Check roaming, country by country
For those leaving from Italy, traveling in the 27 countries of the European Union allows you to use calls, SMS and data under the conditions set out in your national offer. The rule also applies in Iceland, Liechtenstein and Norway and, from 2026, in Moldova and Ukraine. However, there may be fair usage limits on data, especially in offers with many gigabytes or unlimited traffic. Outside this area, rates and packages depend on the operator: the United Kingdom, for example, does not automatically fall into the European system, although some companies continue to include it in their offers. The conditions must be checked in the app or on the operator’s website before departure. Assumptions, in the bill, have their own rate. The official European Union guide explains coverage and limits of roaming at a national rate.
Special attention is needed on ships and planes. When the phone connects to a terrestrial network, the normal conditions apply; if it hooks up to a satellite system, the European rules and related tariff caps stop applying. On the open sea, airplane mode can therefore prevent some harmless notification from returning to land dressed as an extraordinary expense.
Before leaving, it is useful to check how many gigabytes will actually be available, how much calls made and received outside the EU cost and whether there is a daily or weekly pass. Those who decide to only use Wi-Fi can deactivate data roaming and turn it back on when they have chosen a local solution.
Choose between Italian SIM, local SIM and eSIM
When the Italian offer becomes too expensive, a local SIM or one Travel eSIM allows you to purchase a data package valid in the destination country. The eSIM is a digital card: it is installed from the phone’s settings, often through a QR code, without physically replacing the main SIM.
The device must be compatible and free to use other operators’ networks. Apple recommends checking these requirements before traveling and installing the profile while you still have a stable Wi-Fi connection; Google also indicates international prepaid eSIMs as a solution to avoid traditional roaming on compatible phones. Apple explains how to use an eSIM abroad, while Google collects guidance for Pixel devices.
On Dual SIM phones you can keep the Italian number active to receive messages and codes, but assign the data connection to the line purchased for the trip. This selection must be checked in the settings: having two SIMs and leaving the data on the wrong one is a very technological method to pay for old-fashioned roaming.
Download maps before you need them
An active data connection does not guarantee coverage everywhere. Tunnels, rural areas, mountains and crowded neighborhoods can make the signal disappear just as you look for the last turn towards the hotel.
Google Maps allows you to download a portion of the territory in advance and continue using it for offline navigation. The map preserves streets and routes, while real-time information such as traffic and closures requires a connection. Apple Maps also lets you select an area, check its weight, and store it on your device. Instructions are available in the official Google Maps and Apple guides.
Together with the maps, it is convenient to save tickets, reservations, insurance policy, accommodation address and essential contact details on your phone. A local copy in PDF or notes continues to exist even when the airline app decides to ask for an update at the most inconvenient time.
Turn on device location tracking
“Where is” on Apple devices and “Find Hub” on Android can show the location of a lost phone, ring it, lock it and, when necessary, remotely wipe it. These functions must be configured before the device ends up in the seat of a taxi headed elsewhere.
Apple allows you to use the Find My app or the iCloud web service to locate and mark a device as lost. Google lets you search, secure, or erase phones and tablets associated with your account through Find Hub; on supported models the network can contribute to the search even when the device is offline. Here are Apple’s instructions and here are Google’s.
Before you leave, it’s a good idea to try logging in from another phone or computer, check your account password, and set a strong lock code. Tracking helps protect data and provide information to authorities or the facility where the device was left behind; personally chasing the dot on the map remains a terrible tourist excursion.
Only consider a separate phone when you really need it
Carrying a second smartphone configured with a few essential accounts can make sense for those who travel with confidential professional documents or hold particularly exposed roles: journalists, managers, researchers, political personnel and people headed to destinations considered to be at high digital risk. The Canadian Center for Cyber Security reports that the devices of high-profile travelers can be targeted to access sensitive data and work networks.
For a normal vacation, buying a disposable phone risks adding another item to charge, set up and possibly lose. A recent backup, system updates, a good access code and removing files from the device that you won’t need during the trip are more appropriate. Public recommendations on travel cybersecurity focus primarily on the physical protection of devices, strong passwords and tracking functions.
The charger can end up in your suitcase at the last minute. The data plan, maps and remote locking require a few more minutes: when the smartphone connects to the first foreign network, the time for calmly making settings is already over.
