Common Questions

Is an eSIM worth getting for sightseeing across Asia?

You walk through Singapore Changi Airport with your hotel address ready in Grab, passing the SIM counter queue instead of joining it. You book a ride towards Chinatown, follow the route on Google Maps and message your host on WhatsApp about where to meet. Your saved payment card handles the Grab fare, so you can concentrate on spotting the shophouses as the car turns into the neighbourhood.

At a hawker centre, you use Google Translate to understand a stall sign and choose lunch from the menu. You keep a card handy for stalls that accept it and cash for those that do not. Then you book a Gardens by the Bay ticket, pull up the entrance route and send a photo home through WhatsApp. Back at your hotel, you browse GrabFood and order dinner while deciding which garden photographs to share.

What should tourists compare when choosing an eSIM for Asia?

Look for a regional eSIM that covers your actual route, whether that includes Japan, Thailand or Singapore, and has local network reach around your sightseeing stops. This Asia plan covers all three, alongside its other listed destinations. Choose for the places you visit, not just the regional name.

Also look for hotspot support, data top-ups and preparation before departure. This plan supports hotspot on most packages and lets you add more data. It supports installation before you fly, with 180 days from purchase to activate. Your data allowance and validity depend on the package you choose.

Where does the Asia eSIM have the best coverage?

Your Asia eSIM uses local networks including Optus, Telstra, Telkomsel, Pelephone, Jio, Vodafone, IDEA, AirTel, with 3G/4G/5G connectivity across the covered destinations. Coverage is strongest in cities and main tourist areas such as Tokyo, Bangkok, Singapore and Bali. It becomes patchier in Japan’s mountain interior, Indonesia’s outer islands and Australia’s remote outback, where settlements and network infrastructure are farther apart.

What should I download and pack for travelling around Asia?

  • Download offline Google Maps areas for Bangkok and Singapore before heading out, including your accommodation and saved restaurant locations.
  • Save hotel addresses in Japanese for Japan; keep screenshots available when asking for directions away from Wi-Fi.
  • Pack an adapter for Japan’s Type A sockets and Singapore’s Type G sockets, plus a power bank for navigation.
  • Carry cash for Thailand’s market stalls; a displayed payment code may require a banking app you cannot use.
  • Download Grab before exploring Singapore or Thailand, and add a payment card before booking a ride.
  • Use headphones and silence app notifications on trains in Japan; keep conversations quiet around other passengers.
