2. WhatsApp

3. Trainline
Europe has one of the world’s best rail networks, and Trainline makes booking and managing train travel much easier.
The app allows you to search routes, compare operators, purchase tickets and access digital boarding passes across many European countries.
If you’re planning to travel by train between destinations such as Paris, Amsterdam, Rome, Barcelona or Vienna, Trainline is well worth downloading before you leave home.
💡 Roamzy Travel Tip™
Download and sign in to all of your travel apps before leaving home. It’s much easier to configure accounts while you have reliable Wi-Fi than after arriving at a busy international airport.
Stay Connected Wherever You Travel
The best travel apps are even more useful when you have reliable mobile data. Compare our Europe eSIM plans before you travel and enjoy seamless connectivity across multiple European countries.

Although English is widely spoken throughout Europe, Google Translate is still one of the most useful travel apps you can install.
Whether you’re reading restaurant menus in France, understanding railway notices in Germany or asking for directions in Italy, the app helps remove language barriers in seconds.
Some of our favourite features include:
- Camera translation for menus and signs
- Voice conversations
- Offline language downloads
- Text translation in more than 100 languages
Download the languages you’ll need before leaving home so they’re available even without an internet connection.
5. Booking.com
Accommodation plans often change while travelling, especially if you’re touring Europe by train, car or bicycle.
Booking.com makes it easy to:
- Reserve hotels
- Find apartments
- Book guesthouses
- Compare prices
- Read verified reviews
- Manage reservations
We regularly use the app during our own European trips when changing routes or extending our stay in a destination.
6. Rome2Rio
Rome2Rio is one of the best journey-planning tools available for Europe.
Instead of only showing trains or flights, it compares almost every available transport option between two destinations.
It can combine:
- Flights
- Trains
- Buses
- Ferries
- Driving routes
- Walking connections
It’s particularly useful when travelling between smaller towns where several transport options may be available.
7. Citymapper
If you’re visiting major European cities such as London, Paris, Berlin, Barcelona or Amsterdam, Citymapper is one of the easiest ways to navigate local public transport.
The app combines:
- Metro systems
- Buses
- Trams
- Walking directions
- Cycling routes
- Live departure times
For first-time visitors, it removes much of the stress of using unfamiliar transport networks.
Why Reliable Mobile Data Matters
Apps such as Google Maps, Booking.com, Rome2Rio and Citymapper work best when you have a reliable mobile data connection. Instead of searching for public Wi-Fi every time you arrive somewhere new, having mobile data available lets you check directions, transport times and accommodation whenever you need them.
🏙️ City Breaks
Google Maps, Citymapper and Booking.com are usually the three apps you’ll use most often.
🚄 Rail Holidays
Trainline, Rome2Rio and Google Maps make planning train journeys much easier.
🚴 Cycling Tours
Google Maps, weather apps and Booking.com quickly become daily essentials for route planning and accommodation.
🚢 Cruises
Google Maps, WhatsApp and Booking.com are invaluable during shore excursions throughout Europe.
💡 Roamzy Travel Tip™

Compare Europe eSIM Plans8. XE Currency
When travelling between European countries, you’ll often encounter different currencies. While much of Europe uses the Euro (€), destinations such as Switzerland, the United Kingdom, the Czech Republic and Hungary use their own currencies.
XE Currency makes it simple to:
- Convert exchange rates instantly.
- Monitor multiple currencies.
- Work offline using recently updated rates.
- Calculate prices while shopping or dining.
It’s one of those apps you may only use a few times each day, but it can save you from making expensive conversion mistakes.
9. AccuWeather
European weather can change quickly, particularly if you’re travelling through mountain regions or during spring and autumn.
AccuWeather provides detailed forecasts that help you plan sightseeing, hiking, cycling and day trips.
We regularly check the forecast before long cycling days, ferry crossings and mountain train journeys.
- Hourly forecasts
- Rain radar
- Temperature alerts
- Wind forecasts
- Sunrise and sunset times
10. Airline Apps
Whether you’re flying with British Airways, Air France, Lufthansa, Ryanair, easyJet or another airline, downloading the official airline app before departure is highly recommended.
Most airline apps allow you to:
- Check in online.
- Access digital boarding passes.
- Receive gate change notifications.
- Track delays.
- Manage bookings.
Having mobile data means you’ll receive important notifications even while travelling between destinations.
11. Your Europe eSIM App
Many travellers forget that their Europe eSIM provider may also offer an app or online account where they can monitor their data usage, view plan information and manage their eSIM.
Checking your remaining data occasionally helps you avoid surprises during longer holidays, particularly if you’re using maps, social media and video calls regularly.
Installing and activating your Europe eSIM before departure means you’re ready to connect shortly after landing.
