How to use Ubigi eSIM?

Everything you need to know about using an eSIM card

Overview of eSIM

An eSIM card – or virtual SIM card – is a SIM card that is embedded in a mobile device. An eSIM works the same way as a traditional SIM, but you don’t need any physical SIM card anymore. The eSIM is welded in your device and activated over the air. The eSIM is also sometimes called by its technical name, eUICC (Embedded Universal Circuit Card).

So, with an eSIM-enabled device you can easily buy a mobile data plan when you need it, on the go. More and more smartphones, tablets and laptops are equipped with eSIM.

It is amazing

Turn on Data Roaming

Took me a minute to figure out why it wasnt working once i was in Japan. You need to turn data roaming on once the esim is on and your sim is off.

Reliable and Convenient Service for Travel and Everyday Use

I discovered this service last year and have been using it ever since. The signal quality has been consistently good, and l've recommended it to many of my friends. One of the things I appreciate most is the convenience it offers when traveling. You can register before your flight and start using it immediately upon arrival at your destination, which makes the whole experience seamless. Recently, I've also been using it within my own country. I no longer need to purchase another number, and I can easily choose the amount of data (GB) that suits my needs. Overall, it's very convenient and flexible. Highly recommended!
