The eSIM (Embedded SIM) technology is revolutionizing the way we use mobile phones. Unlike traditional SIM cards, eSIM is an embedded module in the phone that can be programmed remotely. This allows for greater flexibility and convenience for users, who can easily switch carriers without the need to replace a physical SIM card. In this article, we will explore the possibilities of eSIM, provide instructions for setting it up on the iPhone 14/15 and the latest Samsung models, and illustrate how using eSIM can help you save money.

What is eSIM?

eSIM, or Embedded SIM, is a technology that enables remote management of carrier profiles on a built-in SIM card in the device.
