Used Ubigi for my Japan trip
It was nice I could download it before landing in Japan. It was activated immediately I landed. I like the fact that I could see my daily usage. In Tokyo, I had access to 5G which is commendable

Works very well!
The eSIM continues to work well. I have a recurring yearly data plan and every so often I buy a one-off plan either for travel or if I run out of data that month. The regional / home geo feature is unique in a travel SIM as far as I know.

Not bad
Not bad. I needed to use this in Japan for Google maps and Disney. I was there for 10 days with 10MB and I ran out of data on my last day. The WiFi was pretty average. There were times I couldn’t get it.

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?
