Phone manufacturers are looking for ways to save space inside the phone in every possible aspect. One of the new solutions allowing for a small saving of space in the device is the change of the size of the SIM card from nanoSIM card to eSIM card which is embedded in the phone. This solution was used, among others, by Apple while creating the latest iPhones (XR, XS and XS Max). A considerable disadvantage of this idea is certainly the lack of the possibility of easy movement of the SIM card between devices, but it seems that eSIM card will soon become a standard in smartphones. This may be proved by Google's support for manufacturers, which aims to help with the implementation of eSIM to smartphones.

Google has begun development of the program, which aims to help developers of phones with Android system to produce devices that support eSIM technology. According to Google, mass implementation of eSIM cards for smartphones, watches, tablets or laptops is a matter of time, and American company sees in this solution many advantages. By its new program, the company offers help to the manufacturers which is based, among other things, on the company's experience so far, and more specifically on the implementation of eSIM input for Pixel 2 and Pixel 3.
