5 Essential Apps for Overseas Travel: Flights, Stays, eSIM, Tours, and Insurance
Traveling abroad is exciting, but You need to choose flights, book accommodation, and prepare travel insurance.
If you travel without proper preparation, you may spend more money than expected or waste time on transport and procedures after arrival.
In this article, I introduce five useful travel apps that I personally use while living a nomad lifestyle in different countries and cities every month.
- Skyscanner: Flight Comparison App
- Airbnb: Accommodation Booking Service
- ESIM4TRAVEL: International eSIM Service
- Klook: Local Activities and Ticket Booking
- SafetyWing: Travel and Nomad Insurance
By knowing these apps, you can plan your trip more efficiently and at a lower cost, and also help you avoid unexpected problems during your travels.
① Skyscanner

Skyscanner is a flight comparison service that lets you search flights from airlines and travel agencies all over the world.
You simply enter your departure city, destination, and dates to find the cheapest and fastest routes.
- Compare flights from over 1,200 airlines and travel agencies
- Sort results by lowest price or shortest travel time
- Flexible date search to find cheaper travel days
Flight prices change depending on the booking date, seller, and search timing.
In many cases, prices can change a lot even if your departure date is just one day different.
For trips with layovers, booking flights through the agencies shown on Skyscanner is often cheaper than buying tickets separately from each airline.
By using Skyscanner, you can compare many routes and options at once and quickly find the best-value flight.
② Airbnb

Airbnb is a booking platform where you can stay in apartments, houses, or private rooms, not only hotels.
It works well for both short trips and long stays.
- Stay in local apartments or homes
- Search for discounts for long-term stays
- Choose places with kitchens for cooking
For stays longer than one week, Airbnb is often cheaper than hotels and offers higher overall comfort.
Many Airbnb places have a kitchen and washing machine, so you can live more like a local.
Some shared houses also have common kitchens, which makes it easy to meet other travelers.
If you understand these rules, Airbnb is a very practical option for long-term stays.
③ ESIM4TRAVEL

ESIM4TRAVEL lets you set up mobile internet on your phone before traveling abroad.
You can use the internet immediately after arrival without buying a physical SIM card.
- No physical SIM card, all setup is online
- Cheaper than local tourist SIM cards
- Easy to buy more data through the app
- Internet works right after landing at the airport
Are you still buying SIM cards at the airport?
With an eSIM, you do not need to buy expensive tourist SIM cards after arrival.
If you install the eSIM before your trip, you can use maps and ride-hailing apps like Uber as soon as you land.
ESIM4TRAVEL offers excellent value. For example, in Europe, you can use 1GB of data for only €0.8.

④ Klook

Klook is a service that lets you book tours, transport tickets, and attraction entry tickets in advance.
By booking online, you can avoid long lines and save time.

Klook also offers many tours and activities, so you can freely customize your travel plan based on your interests and schedule.
Using Klook helps you enjoy sightseeing more efficiently and make the most of your limited travel time.
⑤ SafetyWing

SafetyWing is an insurance service designed for travelers and digital nomads.
It covers medical expenses and travel-related problems during overseas stays.

- Insurance period starts from 5 days
*Example: 5 days costs $10.05 - No waiting period when joining from abroad

Many credit card travel insurances do not cover lost baggage. Their medical coverage is often not enough for expensive healthcare abroad.
Medical costs in countries like the EU, the US, and Canada are very high. In Europe, lost baggage, pickpocketing, and theft are also common.
With SafetyWing, you can get up to $250,000 in medical coverage starting from just $10.05 for 5 days.
It also covers many common travel problems.
