What is an eSIM profile ?

An eSIM profile is the software that you must download to your eSIM-enabled device to access the carrier’s mobile network. It is different from a conventional SIM card that is a physical card inserted into a device and that is removable.

To install the eSIM profile on your device’s embedded eSIM, carriers usually provide one of the following options:

– A QR code (or activation code) that you scan with your device for automatic installation

– Automatic installation of the eSIM profile, either:
> via the carrier’s app, or
> through a deeplink provided by your eSIM carrier

With Ubigi for example, you just need to follow the step-by- step guide here to install your eSIM profile automatically from the Ubigi app depending on your device.

Great eSIM for Japan

I spent a week and a half in Japan, a few weeks ago, and one of the biggest things that the guides kept mentioning online was to get a Japanese eSIM while I was in the country. After checking a few reddit threads about it, I decided to go with Ubigi. The coverage and speed were both great, and the app made everything very easy.
