With AT&T, you can also automatically set up your eSIM over Wi-Fi when purchasing the phone.
“AT&T embraces the customer benefits of eSIM, and will enable new and existing customers to activate their new iPhone 14 using eSIM online and in store,” said AT&T to ZDNET.
If switching from another carrier to AT&T with an approved, unlocked, eSIM capable phone, all you have to do is download the AT&T app to set up an account and activate the phone, eliminating the need to go to the physical store.
Another perk of the eSIM is that if you already have a phone number with AT&T and simply wish to move it to another eSIM supporting device, you can do that online as well.
You can find step-by-step directions on the AT&T website.
