It was really hard to connect once we got to the destination. It said it would happen “automatically”, however it did not happen until we got to the hotel making the travel from the airport difficult. Once it did connect there were no issues.

I was able to activate my SIM card the earliest after arriving in Japan. I usually have a hard time getting connected with other carriers so I will recommend Ubigi to all my friends.

Great value
Very easy to get the eSIM, worked great, the app showed how much was spent. Also, a nice bonus was the -20% code for a friend, so my friend could get the same eSIM for a cheaper price.

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.

Current plan: •

If you choose to add a new one, the current plan will be removed. What would you like to do?
