Learn about eSIMs and how they work with AT&T.

What is an eSIM?

An eSIM is a digital SIM that connects your devices to the AT&T network. It gives you more flexibility to manage your wireless plan and device.

  • You download an eSIM and activate it, so you don’t have to manage a physical SIM card.
  • Some devices with eSIM capabilities can support more than one phone number.

Get started with an eSIM

  • Activating a new AT&T phone? Just turn on your new phone and follow the prompts to download your eSIM.
  • Transferring your number from another provider? Be sure to activate your phone first. Then turn it on and follow the prompts to download your eSIM.

Move my number to another phone

Here's how to move your eSIM (and phone number) between devices:

  1. Start at Bring Your Own Device.
  2. Select Switch the device used on my line.
  3. Follow the prompts to download and activate your eSIM.
