Easy to setup and mobile signal was good. Simple to top up and you can even top up if you’ve already run out of data. Did not give full rating as its a little pricey but for the quality of the calls, it is worth it

Overall good experience
Overall good experience. Easy purchase and installation, good connection even at rural areas in Japan. However, I wished that the reminder to prompt exhaustion or end of data usage could be delivered via direct notification from app rather than email as it would be too late to renew it as there the phone is already cut off from any connections. Fortunately I am able to use my friend’s hotspot to purchase another package.

It works amazingly
It works amazingly. However. We had to do some risky public WiFi connections to figure out what was wrong with our connection as it didnt work off the bat like intended

Great experience
Great experience! Worked even in the mountains and steep hills of Hakone!!! Only place it struggled was the deep subways which is to be expected. Would recommend to anyone!

Worked Well!
This is my 2nd time using Ubigi, this time in Italy. I initially had problems setting it up after buying it through the app, but the customer service team was able to help me troubleshoot and then send me a QR code to activate my eSIM. it worked great for the rest of my trip!

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?
