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:
| Plan | Data | Plan Cost | |
|---|---|---|---|
| 1GB data | US$5.00 7 days validity | See deal |
| 2GB data | US$9.50 15 days validity | See deal |

As a special offer for May 2025, you can get a 10% discount on all Asialink eSIMs. Simply enter the KEN10 voucher code at checkout. This offer is only available if you're new to Airalo.
If you've already used an Airalo eSIM in the past, you can use the KEN5 voucher code to get a 5% discount on your plan.
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.

Am I able to access Google maps with airola esim card for China
Ken replied:
Hi Catherine,
Thank you for your comment. Yes, it should be possible to access Western apps such as Google Maps using an Airalo eSIM for China. Having said that, do be aware that Google Maps does not work very well in China for a number of other reasons that are unrelated to the eSIM (e.g. outdated data, GPS offsetting, etc).
Hope this helps,
Ken
