When travelling overseas, staying connected is no longer optional. Whether you are trying to book transportation, navigate an unfamiliar city or handle essential verifications like banking OTPs, your phone is a critical tool. Many travellers automatically assume they need to buy a local SIM or rent a pocket WiFi device. These options can easily cost around 500 yen per day, which becomes 3500 yen for a one-week trip.
But if you are using Rakuten Mobile, you might already have everything you need. Thanks to its simple international roaming structure, no complicated setup and no extra hardware, Rakuten Mobile can save you both time and money in several real-world travel scenarios. Below are five practical examples where having Rakuten Mobile gives you an advantage that many people overlook.

1. Booking taxis abroad without hunting for WiFi
One of the most frustrating moments during a trip is right after you land. You step out of the airport, ready to move, but your phone has no data because you have not yet bought a SIM or connected to WiFi. Airport WiFi is often congested, and public networks feel insecure for logging in to apps like Uber, Grab or Bolt.
With Rakuten Mobile, your roaming connection activates automatically. You can open your preferred taxi app, check real-time prices and book a ride immediately. There is no standing in long lines at airport SIM counters, no configuration and no need to carry pocket WiFi equipment.
Compared to spending 500 yen per day on pocket WiFi, the convenience alone is worth it. For a week-long holiday, the savings add up quickly, especially because Rakuten Mobile lets you stay connected with your original number.

2. Receiving SMS OTPs while overseas for banking and essential apps
This is an area where many travellers run into trouble. Modern banking apps, email services and booking platforms often require SMS OTP verification. If you depend on a local SIM card abroad, your original number becomes inactive, and you will not receive OTPs.
Rakuten Mobile solves this elegantly. Incoming SMS messages are free even overseas, which means you can continue verifying logins without disruption. This is extremely useful for:
Online banking authentication
Credit card alerts
Airline check-in confirmations
Password reset requests
If you have ever been locked out of your banking app during travel, you know how stressful that situation can be. Rakuten Mobile removes this risk entirely.
3. Using translation apps at immigration and customs
Immigration and customs checkpoints are places where you cannot rely on airport WiFi. You may need to explain the purpose of your visit, show hotel reservations or answer questions. Translation apps are extremely helpful in such moments, but they require stable data.
Rakuten Mobile’s roaming data lets you open translation tools instantly. You can translate your hotel address, clarify luggage contents or ask simple questions without the embarrassment of communication barriers. This allows you to move through immigration faster and avoid delays that happen when you cannot communicate clearly.
Pocket WiFi devices need to be turned on, charged and paired before they work. If the battery dies or if the connection drops during customs inspection, the timing could not be worse. Rakuten Mobile eliminates this scenario completely.

4. Navigating local cities with real-time maps and transit updates
Navigation is one of the biggest data consumers during travel. Whether you walk through Seoul, take the tram in Melbourne or find the right metro exit in Singapore, real-time maps save you from wandering in the wrong direction.
Rakuten Mobile roaming gives you immediate access to:
Google Maps
Apple Maps
Local transit apps
Restaurant and shopping searches
Street level navigation
Instead of depending on hotel WiFi or waiting to buy a SIM card in town, you are connected from the moment you leave the airport. Considering a typical pocket WiFi weekly rental costs around 3500 yen, using your existing Rakuten Mobile connection is a clear win.

5. Contacting your hotel or guesthouse instantly
A simple but important travel requirement is contacting your accommodation. You might need to confirm early check-in, update arrival time, get directions or inform the host about a delay. Without data or SMS, these tasks become unnecessarily complicated.
With Rakuten Mobile, you can call over data apps, send messages through booking platforms or email the hotel without waiting for WiFi access. Many hotels now use app-based chat systems instead of traditional calls, so having instant data becomes essential.
This is especially helpful if your flight is delayed or your luggage takes too long at baggage claim. You can update your hotel on the spot instead of searching for WiFi around the airport.
Comparing Rakuten Mobile to local SIMs and pocket WiFi
Local SIM cards
To use a local SIM abroad, you must remove your Japanese SIM, which disables your original number. That means no SMS OTPs and no incoming calls. Temporary SIM packs usually cost between 1000 to 3000 yen, depending on data allowance, and you must go through the activation process after landing.

Pocket WiFi rentals
Pocket WiFi generally costs around 500 yen per day. For a 7-day trip, that is 3500 yen. You must carry an extra device, ensure it is charged and return it at the end of the trip. Signal quality depends on the battery health and the country’s local network coverage.
Rakuten Mobile
Rakuten Mobile requires no extra device, no physical SIM change and no activation at the airport. You keep your Japanese number active, receive SMS OTPs, make calls through apps and enjoy roaming data without logistical overhead.
When you compare time saved and money avoided on rentals, Rakuten Mobile emerges as a more practical choice for frequent travellers and short vacations.
Final Thoughts
Travel should feel smooth, not stressful. Having mobile data from the moment you land can make a huge difference in how confidently you move through a new country. From taxis to maps to hotel communication, Rakuten Mobile provides a seamless travel experience without the cost of pocket WiFi or the hassle of switching SIM cards.
