The Rakuten Mini smartphone is equipped with an eSIM.
Thanks to the eSIM, you will be able to use dual SIM cards. It means that the eSIM on Rakuten Mini allows you to immediately connect to another mobile operator without using a physical SIM card.
To activate your eSIM, you need a wireless service carrier which provides you an eSIM profile as well as data plans. eSIM data plans availability may vary depending on country and carrier. Ubigi is one of the carriers that support eSIM for the Rakuten Mini, in about 190 destinations, on the 5 continents.
The activation possibility of the eSIM feature might differ by country and/ or model version of the device. Ubigi is not responsible for this inconvenience.

Best of the Best
Best of the Best, second to none. When it comes to usage in Japan, Ubigi is better than Mobal, Sakura Mobile, Rakuten, trifa and other competitors. I use it with my travel router and I couldn't be happier, I hold 5G connectivity better with them, have never seen signal drops and the Smart IP is a nice feature. Great quality for the price and the ability to top up is very smooth and seamless. Unlimited data plans are also perfect, I would love to have more above the 60GB data cap before the unlimited data speeds changes to 2Mbps but Ubigi is still by far the best! I've always recommended Ubigi to friends and family and will continue to do so.

Seamless, straight forward and easy to use. I downloaded it at at the airport before my flight, off of reviews. Don't regret it. Now I get to use it for all my travels.

It is an amazing book about Mystery of Princess Diana!
The story begins with facts and then swings to dreams, speculations, alternative reality, total craziness. But then the reader realizes that s/he must start from scratch to re-create the story. And the story sometimes is annoying, but fascinating. It is not only a good reading experience but also an experience of shape shifting words inside the story. Great storytelling skills and bravery to go in places where not easy to go.
