eSIM is a new standard that should make it easier to switch carriers, or to add a second line to your existing phone.
Now those SIMs are going digital (or "e") and moving your information to a reprogrammable, embedded chip

A SIM card is a "subscriber identity module." Required in all GSM, LTE, and 5G devices, it's a chip that holds your customer ID and details of how your phone can connect to its mobile network

 An eSIM takes the circuitry of a SIM, solders it directly to a device's board, and makes it remotely reprogrammable through software.

The original drive toward eSIM came in part from the "Internet of Things" industry. Being tiny, and not requiring extra room for a slot, eSIMs can be built into devices like drones, wearables, sensors, and location trackers, where size is of the essence. 


What Does eSIM Let You Do?

Simply put, eSIM lets you change your wireless carrier, data, or service plan through software. On eSIM devices, in general, you can go to a menu or take a photo of a QR code to change your carrier or service plan on the fly. You don't need to go to a store, wait for the mail, or fiddle with a tiny chip. You can also often use two different lines on the same device, such as a home and work line, or switch between different plans depending on where you are.


Which Phones Support eSIM?

All three major US carriers support eSIM on recent iPhone and Google Pixel models. The folding Moto Razr also supports eSIM. But while the Samsung Galaxy S20, Note 20 series, Z Fold 2, and S21 series have supported eSIM in theory, they haven't supported them in practice in the US, probably because of carrier resistance.
