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 Sony 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 Sony 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.

Excellent coverage!
I had some horrible experiences with eSims; Ubigi restored my faith. Purchase was seamless and easy; it worked first time in France, then the UK, Ireland and the USA. It does what it says on the tin. Full marks!

Great
Great, the coverage with NTT Docomo in Japan has been great so far. Was easy to setup and install the eSim and 15 day pass activated when we landed at the airport.

The communication response has been prompt. The only thing I would suggest is that we have a YouTube presentation on how to synchronise with the vehicle.

Great coverage
Great coverage, no issues with it once it connected but it did take a little while to connect and provide internet that first time. I was on a train traveling and maybe the signal was not good enough to initially connect and set up. Once in Munich it was fine.

Honestly
Honestly, I am not satisfied with the service. I even considered giving it only three stars.
When there is a signal, everything works fine, but it seems that a large part of London is not properly covered. Today, I was without an internet connection for almost two hours while walking around the London Eye and Big Ben. In the 21st century, this is simply unacceptable for a mobile service provider, especially in such a central part of London.
As I am planning to use your service again in Italy and France in a few weeks, please check what is causing these coverage and signal-quality issues.
I am using a Samsung Galaxy S25 that is approximately one and a half years old, and I am completely certain that the phone is not the problem. As soon as I disabled the eSIM and switched mobile data to my regular SIM card in roaming, everything started working normally.
