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.

Ubigi is easy to use
Ubigi is easy to use, check, and is a very good value. We have traveled from the USA to the Netherlands and Italy with good service 24/7. Need just 6 more weeks of Ubigi ‘s service and we are done.

Trip to Canada
Bought the esim as it appeared to be good value for an upcoming trip to Canada. I was a bit apprehensive never having had an esim before but checked my phone was compatible before buying.
Email with instructions arrived almost immediately after purchase and downloading the esim to my phone was really quick and easy.
Swapped the active SIM in my phone to the Ubigi esim at the airport when boarding my flight and bingo! Everything worked perfectly when I switched off airplane mode on landing in Canada. Internet, WhatsApp, Google maps etc work fine. Very convenient! Excellent experience at a fraction of the price of upgrading my EE SIM to work in Canada whilst on holiday.
