SIM Cards & eSIMs

Learn about the differences between SIM cards & eSIMs.

SIM Cards vs. eSIM

What is a SIM Card?

A SIM card is a small chip that contains information your device needs to connect to the Boost Infinite network. This card is inserted into your phone and allows you to connect to the network to make/receive calls, send/receive text messages and use data.

A Boost Infinite SIM Kit includes all three SIM sizes (nano, micro and standard), so your device is sure to have a SIM that fits.

What's an eSIM?

An eSIM is a digital SIM that eliminates the need for a physical card. You can quickly and easily transfer or get a new cellular plan, all digitally. You can even store multiple eSIMs on the same device and use two phone numbers at the same time. Plus, it's more secure — someone can't remove an eSIM if your phone is lost or stolen.

Your eSIM needs to be downloaded over a Wi-Fi connection and will allow you to connect to the Boost Infinite network in minutes.

How long will it take to activate my phone?

In most cases, activation just takes a few minutes.
