Asialink Plans

If you're looking for an affordable way to use your cellphone when travelling in Asia, you can get a Asialink eSIM from only US$5 for 7 days usage.

To get a Asialink eSIM, you'll need to have an eSIM-compatible device such as the iPhone 11, Galaxy S20, Pixel 3 or later devices. You can then order your Asialink eSIM through the Airalo app with instant delivery direct to your phone. There's no need to queue at the airport or to register the Asialink eSIM with your ID, saving you lots of time.

The following table shows the eSIM plans that are currently available from Asialink in Asia:

Once you've ordered your Asialink eSIM, it will only activate when your cellphone actually connects to a supported network in Asia. This means the validity period will only begin when you actually land in Asia and turn your cellphone on.

Your Asialink eSIM works with the dual-SIM function on most modern smartphones. This means you can use your regular SIM card alongside the Asialink eSIM (e.g. to receive incoming phone calls and text messages on your normal phone number).

Alternatives to Asialink

The main disadvantage of Asialink is the fact you're getting a data-only service on the eSIM. You will not get a local phone number in Asia when you're using the Asialink eSIM in your phone.

If you'd like to call or text whilst you're travelling in Asia, you'll need to use your normal SIM card instead (on which international roaming fees may apply). Alternatively, you can side-step these charges by making your calls through WhatsApp or other similar apps.

If you're looking for a more fully featured SIM card with a local phone number in Asia, you could consider getting a regular prepaid SIM card upon arrival instead. This will involve some additional hassle (e.g. queuing up at the airport to get your SIM card, a registration process for the SIM card, etc) but it can be preferable and better suited for longer-term use in Asia.

Asialink Coverage

If you're using a Asialink eSIM, you'll have access to coverage from the partner mobile networks from across Asia:

If you're only planning to visit one country on your trip, it may be cheaper to get a country-specific eSIM instead. This will normally be available at a slightly lower price than the Asialink eSIM.

  • Hi Ken
    Love this site!
    I’m off to South Africa in Feb 24 and I have a EE contract, they however do not cover that Country in their Data Roaming, what is the best way I can use my phone over there please?
    Get a sim when I land or do you know any other deals

  • I just arrived in the USA and Airalo is amazing – I bought the the sim on the airport wifi, and had it fully set up and on the network before I got to LAX baggage claim! So easy, no paperwork, didn’t need to find a shop/kiosk, queue, open up the phone or any of that nonsense. Also with dual sim capability I’m still able to use my British number for receiving sms/iMessage.

    It’s good coverage too, and it automatically swaps between AT&T or T-Mobile depending on the area. I’d highly recommend it and look forward to using it in other places in the future.
