    Taking a Verizon Note 20 Ultra to AT&T

    See below for how it should work for AT&T to T-Mobile.

    So I buy a Note 20 Ultra on VZW with an eSIM in it. Then on day 63 it is unlocked.

    On day 64 i put an AT&T nano SIM in it. The device should load and have available both the VZW bands and software and the AT&T bands and software. Similar to the way in which my Pixel 4 worked when i had T-Mobile on the eSIM and AT&T on the nano SIM. Not paying it off, keeping payments on VZW.

    Theoretically, on paper, that's how it should function, correct? Any conditions or caveats I should know about?

    I’ve seen people stating it might take awhile for that carrier configuration profile to be available for new phones. I know the Note 20 series is relatively brand new so it might not yet be available for a particular carrier.

    Once the at&t modem is loaded. VZW configuration is removed. You'll have whatever at&t wants enabled.
