Preparing your phone, data, and internet for travel

• Calls, SMS, and mobile data may be subject to different rates and conditions abroad.
• Save important addresses, tickets, and contacts offline as well.
• Enable only the data options you actually need.
• Bring a charger, a suitable adapter, and a charged power bank.
• Public Wi-Fi networks are convenient, but shouldn’t be your only means of connecting.
• For questions about your plan or roaming, rely on the latest information from your provider.

When using your phone abroad, the price and availability of data, calls, and SMS depend on the destination, your plan, roaming restrictions, and usage limits. For plans from EU providers, “Roam like at home” applies in the EU as well as Iceland, Liechtenstein, and Norway; the rules also cover Ukraine and Moldova. Roaming in the United Kingdom depends on your provider. Fair-use limits and some services may be subject to additional conditions, so check your plan details before traveling.

Write down your customer number, the number to call to block your service, and your provider app login details on paper or in a secure offline location. Also save card-blocking contact numbers outside the app; if you can’t access your payment account, you can still reach the card-blocking service and fee information. Have a second payment option available in case you need to purchase an add-on at short notice; options include a card, cash, and a second payment method.

Download tickets, bookings, map areas, and important messages before you leave. Open the files without an internet connection to check that names, addresses, times, and booking numbers are still legible. Your digitally secured travel documents shouldn’t be stored only in an online inbox. An extra paper copy can make all the difference if your phone runs out of battery or is lost.

Save important contacts with their full names and a short note about their role: accommodation, transfer, insurance, tour guide, or family. For important appointments, also arrange a backup and identify someone you can reach; backup plans, contacts, and Plan B go together. Choose accommodation based on location and destination using the accommodation search.

Public Wi-Fi networks can be handy for quick searches or downloading files. Turn off automatic connections to unknown networks, log out after use, and don’t save important passwords in an unprotected note. Save any maps, addresses, and translations you need for offline use before you leave. For place names written in another script, keep the original names and transliterations together.

If you use a translation app, download the necessary language packs in advance. Also save a few short phrases for accommodation, transport, food, and getting help. This makes it easy to find useful words for everyday situations even without a network connection. For languages using another script, preparing original names and transliterations is helpful.

Fully charge your phone and power bank before setting off, and test your charging cable. Keep your adapter, power bank, and important documents easily accessible in your luggage and carry-on. If traveling in a group, split important files between two devices and keep key details on paper as well.

Before departure, set the correct date and time, make sure you have enough storage, and enable your device lock. Remove unnecessary apps that use data in the background, and back up your photos and documents. The first leg after landing, including your transfer and local public transport, is easier to plan if you can open your destination address and route offline.

A quick practical test is enough: turn off Wi-Fi and mobile data, then open your map, ticket, translation app, and contact list and try a search. If you can still find your accommodation, transfer point, and emergency contact afterward, your digital preparations are ready for everyday use.

Does “Roam like at home” apply on a plane or ship?

No. Onboard phones may connect to satellite networks, which aren’t covered by “Roam like at home” and can incur high additional charges. Watch for your provider’s automatic warning message and turn off mobile data if needed.
