Excellent value, spottier coverage outside of cities
The price for data was excellent. Topping up data was also easy and instantaneous. Mobile coverage was sometimes weaker in smaller towns in France outside of city centers, or inside some buildings. Generally satisfied and would use again for travel in Europe.

I will be using Ubigi eSIM again!
This was my first experience of buying and using an eSIM and, once I had worked out how to override my physical SIM card whilst on holiday, I had no problems and great coverage.

Worked well most of the time.
Worked well most of the time. Noted some problem with reception while inside some train stations and department stores in Osaka and Kyoto.

Great price and connected easily!
Very simple to buy before I left for Portugal and the price was great! I followed the instructions to switch my phone from the home SIM to the Ubigi eSIM, and it connected at the airport soon after I landed. It allowed me to use my phone with my cycling group's What's App, to check museum times, get directions, etc. without any issues at all. Definitely recommend!

Fabulous experience
The entire process was utterly seamless...from online ordering to installation of the eSIM to instant, fast data access upon landing in Tokyo. Will definitely be using Ubigi on my next Japan trip.

Not too bad
Price is okay, but it was a bit unstable at times (sometimes it would just really lag), but most time it worked okay

Great experience - minor set back with initial connection
The connection was always great. The App is easy to understand and use. The explanations and guidance are pro active and easy to understand. I did need to set up my APN before I got initial service. The step-by-step troubleshooting guide on the website worked well in pointing out the potential need to do that, which is excellent! However, I only noticed that is was necessary at the destination were I then had no initial service, which put me under stress. I am wondering if there would be a way of checking possible connectivity ahead of time or recommending checking this setting before? Still I would definitely recommend using Ubigi and will do so in the future again!

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$22.00

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