The best decision that I purchased Ubigi e-sim prior to my travel in Japan. It was so convenient and hassle free . Once I got to Tokyo my eSIM was activated and I was able to use it right away . Just make sure your mobile device is open line.

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: SOUTH KOREA • 10GB • 30 days • US$19.00
If you choose to add a new one, the current plan will be removed. What would you like to do?
