How to activate an eSIM for an Android mobile device?
To activate your eSIM, you need a wireless carrier which provides you an eSIM profile as well as an eSIM data plan.
To download your eSIM profile on your Android device, you may receive an “activation code” from an eSIM carrier. The activation code is in fact a download link. It is often in the format of a QR code that you will scan with the camera of your phone or tablet to install and activate your eSIM profile on your device. It takes just a couple of minutes to complete the whole process and get connected.
Other ways of getting an eSIM profile include downloading the app of your carrier and follow on-screen instructions or going directly through your Android device connectivity settings.

Quick and easy. Worth the money.
Quick, easy and by applying discount codes the cheapest I could find for our Japan trip. Had great connection in almost all places, the country side is a little difficult. But changing provider wont help there. ☺️
