Common Questions

Can an eSIM help me explore Asia without SIM queues?

You roll your suitcase through Changi Airport and open Grab while other travellers queue at a SIM counter. With your Asia eSIM, you can head straight to the pickup point, match the car details and follow the ride into Singapore on Google Maps. Your hotel sends its entrance instructions through WhatsApp, so you know which doorway to look for before the driver pulls up.

After dropping your bag, you head to Chinatown and use Google Maps to find Maxwell Food Centre. You point Google Translate at a menu, choose lunch and send a photo home through WhatsApp. Later, you book a Marina Bay attraction ticket on Klook and keep the confirmation handy on your screen. Back at your room, you browse GrabFood for dinner, compare dishes and follow the delivery progress without heading out again.

What should I look for in an eSIM for Asia?

Choose an Asia eSIM with coverage across your actual route, especially when combining Japan, Thailand and Vietnam. This plan covers those countries alongside other included destinations, using supported local networks in cities and tourist areas. Look for hotspot support for sharing a connection; it works on most plans here.

You can add more data through a top-up. Installation is available before you fly, and you have 180 days from purchase to activate. Activation starts when the eSIM connects to a supported network at your destination. Your data allowance and validity depend on the package you choose.

Where does the Asia eSIM have the strongest coverage?

Your Asia eSIM connects through local networks including Banglalink, Grameenphone, 3, Indosat, Telkomsel, AirTel, Jio, NTT docomo, with 3G/4G/5G connectivity. 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 the remote highlands of Vietnam, where settlements and network infrastructure are farther apart.

What digital travel essentials should I pack for Asia?

  • Save offline maps for Kyoto before exploring its narrow lanes; mark your accommodation entrance as well as its address.
  • Download Grab before visiting Thailand or Vietnam, and add your payment method before requesting a ride.
  • Carry a plug adapter that fits Japan’s flat-pin sockets and Singapore’s rectangular three-pin sockets.
  • Keep a physical payment card and cash handy in Japan; small restaurants may not accept your preferred digital payment method.
  • Save accommodation addresses in Thai for Thailand and Japanese for Japan so you can show them directly to drivers.
  • Download tickets before visiting Bali’s temples, and put your phone away wherever photography is restricted.

How does an eSIM work?

How do I install Asia eSIM on iPhone?

Do I need to turn on Data Roaming for Asia eSIM?

Yes, enable Data Roaming on the eSIM line (not your primary SIM). This allows the eSIM to connect to local networks in Asia. You won't be charged roaming fees—it connects as a local plan with no extra charges from your home carrier.

Can I share my eSIM data on Asia beach trips?

Yes, hotspot and tethering work on most plans. On a beach outing in Phuket, share your connection with a companion so they can browse restaurant menus on their own device.

Will WhatsApp work with a data-only eSIM?

Yes! WhatsApp and iMessage stay linked to your home number. The Asia eSIM is data-only, so your existing messaging apps work perfectly—you keep all your chats and contacts.
