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.

It was a super easy experience, quick to set up and as soon as I landed I was good to go. I had really stable connection in pretty much every spot I visited.

Very easy to install, Great Price and Reliable Network
Very easy to install, application to track status of service is very clean and easy to use. Coverage in Japan was very good with Docomo (NTT) and Ubigi.
Found the Unlimited term for the Unlimited plan a little bit miss leading, it is a shaped plan after 25gb.
Otherwise, great cost per gb for a roaming SIM for data in Japan considering I was using my phone for a lot of video/media content and sharing the internet with a laptop.

Perfect and Affordable!
We used Ubigi while traveling in Portugal last year for the first time. This year, we’re traveling through Greece using Ubigi once again. So far, it’s been great!!

Connectivity in metropolitan cities was great but poor in Nashik …
This worked well in metropolitan cities like Mumbai and Bangalore but had poor or zero connectivity in Nashik. It was advertised as it will work over all major networks. People had no issues with physical sim in Nashik while eSIM did not work there .

Easy connection
I purchased another e-SIM provider, but ended up not being able to use it, not sure why, and that provider was helpful and ended up providing me with a refund. Then, I searched for which e-SIM provider is better to use in Japan, Ubigi pop-up, which I purchased. The connection was easy. I was worried that I couldn't get it connected because usually, I have my husband do that for me. However, surprisingly, it was very easy to connect. Good thing that it was connected just fine, so I won't feel lost without an internet connection, which I might not be able to connect with my family back home. Just a small piece of feedback is that sometimes I would lose the connections, but it will get back on again after a few minutes.
