Excellent service in many countries
Ubigi provide an excellent service in all the countries I have used them. This includes several in Europe, the USA, India and Vietnam. I would definitely recommend them

HK and Tokyo 10GB plan 7 days each
The data plan and number of days duration selection was unbeatable. eSIM easy to buy and install from user friendly app. Support pages were helpful but weren’t really needed. I have already recommended Ubigi to other friends traveling from Canada to Asia.

spotty reception for Ecuador
Ubigi had good guides on how to connect and installing the e-sim was seamless. However when we landed in Ecuador the e-sim took a while to register and start working. Outside of the main city our reception was very spotty. even in large towns on major highways there was very unreliable service.
In Quito the reception and connection was great,

We travelled extensively through many parts of Japan and never had at any time a problem with the internet connections, be it in Osaka, Kanazawa, Kurobe Gorge, Nagano, etc. etc. HOWEVER, if one is deep in an underground station there is no more reception and with these huge stations and masses of people rushing about orientation can be pretty frustrating.

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?
