eSIM is a virtual SIM card, a special chip with the possibility of embedding a code. This module is built into modern phones at the production stage, which allows the data stored on it to be overwritten. This means that a person is not bound to a specific cellular operator and can change the number if desired.
Among the main advantages of such technology is the absence of a SIM card slot on the phone. A physical card can break or get lost, but a virtual one cannot. And most importantly, it is unnecessary to visit a mobile operator’s office to re-record the number. All necessary procedures can be done over the Internet.
Currently, eSIM technology works on a small number of devices. Some Apple and Google phones and several smartwatches support it. However, shortly, almost every budget smartphone will be equipped with a useful chip, making acquiring a mobile number as comfortable as possible.
