Many of the latest smartphones on the market are eSIM compatible devices. An eSIM (embedded subscriber identity module) is a small electronic chip embedded in your phone or device that performs the same function as physical SIM cards. The eSIM is the equivalent of a virtual SIM card. Rather than using a “tool” to remove/insert a physical SIM card and risk losing or damaging it, an eSIM-enabled device can be programmed and reprogrammed automatically by downloading the eSIM profile from an operator via an app or a QR code.
An eSIM a is multi-carrier, it can hold up to five virtual SIM cards at a time and you just need to switch between plans in your mobile device settings.
This Xiaomi model equipped with an eSIM allows you therefore to activate an additional cellular data plan, which you can use locally or internationally, without the need to look for a physical SIM card.
Ubigi allows you to get and install a free eSIM profile on your Xiaomi device. Using an operator like Ubigi, which connects to the local mobile network abroad in over 200 destinations, can be much more economical than paying your usual operator’s roaming charges when you use your Internet connection abroad for leisure or work.

Works great for me.
Bought 15 days Unlimited as it was what I just needed. Notified me and my friends that it will start to activate the moment we have reached within the area of coverage in Japan. I only went to Tokyo, Kyoto, Osaka, and Nara. So please take it with a grain of salt if you are visiting along the lines of rural villages and such.
My phone: Iphone 11 (yes it's old but decided to spend my money for the trip hahahaha)
Using it daily in Japan was good. Using navigation, translation apps, Pikmin Bloom, social media app, and etc was no problem at all. Using it underground at train stations worked normally as well.
There are some slow moments where the video chat became blurry, or youtube/insta videos started lagging, or my manwha reading loaded slowly, but it never just fully cuts off and the lag wasn't bad for me (like 2-3 seconds of lag/blur at most with a frequency of once or twice)
Overall: It was good. Very easy to use. I would recommend it and use it again.
NOTE: While using this, your cellphone will not make & receive calls or text messages! It will specifically use the APP ONLY! HOWEVER you can allow your cellular data provider on your phone to be ON (activated) at the same time in the settings. On the iphone I was able to prioritize Ubigi for data and my provider for text messages and call. For calls I did not answer nor make international calls due to fees. It's a hassle but at least it's good to know important text/call messages during my vacation.

Easy to install and use
Easy to install and use, works fine.
Relocating inside the country (by plane) was kind of confusing at first, but worked fine later.

Good overall, but poor reception in many buildings.
The experience and prices were generally good, but reception in many buildings (old, with thick walls) was quite poor.
