Essential Apps for Thailand: 5 Apps to Download Before Your Flight
נועה רגב4 min read
Heading to Thailand? A handful of apps installed before you even board the plane can save you real time, money, and hassle once you're there.
From navigation and ride-hailing to translation, ferries and internet access - here are 5 apps worth having on your phone before you land in Thailand.
In short: Install all 5 apps and your eSIM before the flight, not after landing. Internet (eSIM) is the baseline requirement — Grab, Maps, Translate and 12Go simply don't work without a connection. Google Maps and Google Translate can and should be downloaded for offline use in advance. 12Go is most useful when your route covers multiple destinations or islands.
1. SimSIM – to land with internet already working
One of the most important things you can do is sort out your internet connection before you fly. With an eSIM, you can install your data plan in advance and connect to the local network the moment you land, no need to hunt for a SIM card counter at the airport.
There's a simple reason for this: almost every other app on this list — Grab, Google Maps, Google Translate, 12Go — simply doesn't work without internet. Connectivity isn't a nice-to-have here, it's the foundation everything else on this list depends on.
You can pick an eSIM plan for Thailand from SimSIM and install it before your flight, so the moment your plane touches down, your phone connects to the local network automatically.
2. Grab – for taxis and rides
Grab is the leading ride-hailing app across Southeast Asia, and in Thailand it's a simple everyday tool: you see a price estimate before you book, and there's no need to explain your destination to the driver or haggle over the fare.
Tip: save your hotel's name in the app ahead of time, especially useful after a long flight when the last thing you want to do is explain an address to a driver.
3. Google Maps – far more than navigation
Many travelers use Google Maps just for directions, but in Thailand it does a lot more:
- Walking and driving directions between sights and restaurants
- Finding nearby restaurants and attractions
- Reviews from locals and other travelers
- Saving places ("Saved") to plan out your day
- Downloading maps for offline use — handy when you have no signal or want to save data
That last tip is the one many travelers miss: you can download the area you're planning to visit for offline use in advance, so navigation keeps working even in spots with weak reception.
4. Google Translate – when English isn't enough
In the major tourist areas, basic English usually gets you by, but the moment you step outside them — local markets, menus, road signs — Google Translate becomes essential. You can translate text, speak and get a spoken translation back, or point your camera at a sign or menu in Thai for a real-time translation.
Download the Thai language pack for offline use before your flight. That way you can still translate even when you lose signal temporarily, like on the way from the airport or in more remote areas.
5. 12Go – for getting between islands and destinations
12Go is less well-known than the other apps on this list, but it's a key tool for anyone planning to move between multiple destinations in Thailand. The app lets you compare and book ferries, buses, trains and sometimes even domestic flights, all in one place, with schedules and prices included.
For example, if your route includes Bangkok → Koh Samui, Koh Samui → Koh Phangan, or Phuket → Koh Phi Phi, that's exactly the kind of connection 12Go is built for.
If you're still mapping out your route, the full guide to eSIMs in Thailand can help you figure out how much data you'll need at each stage of the trip. And if you're not sure exactly when to activate your eSIM, this quick guide answers that exact question.
Before You Board
A quick checklist to run through a day or two before your flight:
- Install all the apps in advance
- Log in to your accounts (Google, Grab, etc.)
- Add a payment method in apps that require one, if needed
- Download maps and translations for offline use
- Install your eSIM in advance
- Save the address of your first hotel
That way, when you land in Thailand, instead of dealing with downloads, SIM cards, and settings, you can simply connect and start your trip.
Frequently asked questions
Do I need an eSIM for the other apps on this list to work?
In practice, yes. Grab, Google Maps (in online mode), Google Translate (in online mode), and 12Go all need an internet connection to work. An eSIM that's installed and active from the moment you land is what lets everything else on this list actually function.
What happens if I don't download the maps and translations in advance?
Google Maps and Google Translate will still work as long as you have an internet connection, but without downloading the area and language for offline use, you're dependent on continuous signal. That can be an issue in areas with weak reception, so it's worth downloading both before your flight.
Does Grab work everywhere in Thailand?
Grab operates mainly in major cities and tourist areas like Bangkok, Chiang Mai, Phuket, and Koh Samui. In more remote areas or smaller islands, its coverage is limited, so it's worth checking local availability or relying on taxis and hotel transport instead.
When is it worth using 12Go instead of booking directly at the station?
12Go is most useful when your route includes several connections between islands or cities, since it lets you compare times and prices in advance and book without relying on information you only get on the ground. For a single, short trip, you can often just buy a ticket at the station.
