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.

I have used Ubigi a few times
I have used Ubigi a few times, and I have not got any problems with Ubigi. It's simple and it's easy and I really find it helpful now that a lot of the actions are automated with the new process!

Very good connection
Very good connection which is the most important. I just had some difficulties in activating it as it hasn't connected automatically when I was at place as it was supposed to do.

The entire family used the Ubigi eSIM…
The entire family used the Ubigi eSIM for a week white in Tokyo Japan, and it worked flawlessly. Much better than Airalo. Actually 1 of the 4 family members on the trip had Airalo, and Airalo stopped working after day 2. He ended up switching to Ubigi. We would not have been able to navigate out way in Tokyo with the Ubigi’s reliable service.

Diverse plan
I hope you’ll have plans for 5 days unlimited. I only used for 5 days and there are no options. Or something like we can choose how many days and there is a day rate

Easy to use and ready as soon as we got off plane.
Got the ESIM before we took the plane to Japan. Once we landed and turned it on service has been great. Very easy to turn on just check their instructions and turn your main service line off( so your phone isn’t trying to use both. Can still text/call with WhatsApp/fb messenger/ iPhone. Would def recommend

How to check if a device is ready for eSIM?
Check eSIM compatibility
Smartphones & Cellular Tablets:
Dial (*#06#). If an EID number shows, your device supports eSIM!
Laptops (Windows 10/11):
Open your flyout (bottom-right corner). If Cellular settings are visible, your laptop supports eSIM!
Check Carrier Unlock
On iOS:
Go to Settings > General > About, scroll to Carrier Lock. If it says "No SIM restrictions", your device is unlocked!
On Android:
Go to Settings > Network & Internet > Mobile Network, turn off Auto network selection. If you see multiple available networks, your device is unlocked! If only one appears, or you get an error, it may be locked.
You already have an eSIM in your cart.
Each order can only include one eSIM data plan.
If you choose to add a new one, the current plan will be removed. What would you like to do?
