Planning a trip and wondering how to stay connected abroad without sky-high roaming fees or SIM card hassles? Look no further than Airalo, the world’s first eSIM store for travellers. In this guide, we’ll show you how Airalo makes it easy to stay online in Thailand, Japan, and beyond – with insider tips from our own family holiday.
📲 What Is Airalo and Why Use an eSIM When Travelling?
An eSIM (embedded SIM) is a digital SIM card that lets you connect to mobile networks abroad without inserting a physical chip. Airalo offers prepaid data-only eSIMs in over 200 countries — perfect for travellers who need reliable internet for maps, bookings, and social media on the go.
Benefits of Airalo for travel:
- Connect instantly after landing – no airport SIM queues
- Avoid expensive roaming charges
- Affordable data plans tailored to your destination
- Works with most phones (iPhone, Samsung, Google Pixel and more)
- Quick top-ups via the Airalo app
Best eSIM for Thailand Travel
Planning a trip to Thailand? Airalo partners with DTAC – one of the country’s leading mobile networks – to offer strong coverage across Bangkok, Chiang Mai, Phuket and Krabi.
We recommend downloading the Airalo app and installing your Thailand eSIM before leaving the UK so you’re online the moment you land. It’s ideal for browsing local restaurants, booking transport, and staying in touch with friends back home.
Best eSIM for Japan Travel
Japan is one of our favourite destinations – and staying connected was effortless with Airalo’s Moshi Moshi eSIM, powered by SoftBank and KDDI networks.
During our recent family trip to Japan, we used the 10GB plan for two weeks. It covered everything from train schedules to restaurant reviews and helped entertain the kids during long rides. We activated it before departure, and it worked instantly after landing in Osaka.
🚫 Limitations: Airalo eSIMs are great for data-only travel. If you’re visiting multiple countries or need to make calls (like booking hotels or contacting guides), Airalo is not suitable – it doesn’t offer a local phone number or voice minutes.
🚀 How to Get Started with Airalo
Setting up Airalo takes just minutes:
- Download the Airalo app
- Search for your destination (e.g. Thailand or Japan)
- Choose your preferred data plan
- Install the eSIM following the app’s step-by-step guide
- Activate it – and you’re ready to go!
