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.

Simple and Good rate
Straightforward, quick, easy, just turned off my other sim and activated this one when I was close to my destination, unlimited made it easy not to worry about needing information on the go and away from home.

SO "Easy to connect"
Easy to connect - Keeps my local NZ number when in Japan for 3 months and can turn off my NZ Data Roaming and everything syncs perfectly (contacts, maps, Wifi calling, WhatApp and MEssenger, Mail etc) for 65yr old to user - Its like using it at home... Set up the week before we left and it activate when landed...So USER Friendly - Legends and thanks
