FairSIM

Asia eSIM

Southeast Asia is built for multi-country trips: Bangkok to Chiang Mai to Hanoi, Singapore to Kuala Lumpur to Bali, or a Korea and Taiwan double. Each new country means a new SIM counter, a new passport check and, in Thailand, a face scan. Or one Asia plan.

The FairSIM Asia eSIM covers 14 countries at one wholesale rate, joining AIS in Thailand, Viettel in Vietnam, Singtel in Singapore, Telkomsel in Indonesia, SK Telecom in Korea and Telstra in Australia. Install once, keep it on, and cross borders by bus, ferry or budget airline without touching Settings. Japan, India and the Philippines have their own single-country plans.

How FairSIM works

  1. 1

    Pick a destination and a plan

    Choose the country or region and the data you need. The price you see is the price you pay.

  2. 2

    Tap install

    On iPhone (iOS 17.4+) the eSIM installs in one tap, no QR code. Do it at home while you still have Wi-Fi.

  3. 3

    Land and connect

    Turn on data roaming for the FairSIM line when you arrive. Your plan starts when it first connects.

Asia eSIM questions

Which countries does the Asia eSIM cover?

Thailand, Vietnam, Malaysia, Singapore, Indonesia, South Korea, Taiwan, Hong Kong, Macao, Sri Lanka, Pakistan, Uzbekistan, Australia and New Zealand. The full list is on this page and in the app.

Is Japan included?

No. Japan, India and the Philippines are sold as single-country plans. Buy those separately in the app, or pick the Asia plan for the Southeast Asia and Pacific part of the trip.

Do I need to register the eSIM in Thailand or Indonesia?

No. Registration and IMEI rules apply to local SIMs. A foreign travel eSIM roams and is exempt.

Do WhatsApp and LINE calls work?

Yes, over data. The plan is data-only, so keep your home SIM active for SMS codes.

How much data do I need for a month across Asia?

About 20 GB for maps, Grab, messaging and photos; more if you stream or work from cafés.

What is an eSIM?

A SIM card built into your phone. Instead of a plastic chip, you download a profile. Every iPhone since the XS has one next to the physical SIM slot, so your home number stays put while FairSIM supplies the data.

Is my phone compatible?

FairSIM works with eSIM-compatible, carrier-unlocked iPhones: the XS, XR and everything newer. iOS 17.4 or later unlocks the one-tap install with no QR code. Check the full list on the How it works page.

When should I install my eSIM?

Before you travel, while you still have Wi-Fi. Installing does not start your plan; the validity typically starts when the eSIM first connects to a network at your destination.

Do FairSIM eSIMs come with a phone number?

No. FairSIM eSIMs are data-only by design, which keeps costs low. For calls and texts, your physical SIM stays active so you keep your existing number, and WhatsApp, FaceTime and iMessage work over data.
