Will this phone work on First Net by ATT? null

FirstNet has an extensive list of approved devices that works within the AT&T FirstNet Network. From my experience, if you're looking to use the eSIM feature, you will need a physical card with a QR Code to authenticate your account on the phone. As of the time of this posting, OnePlus phones are compatible with AT&T, but not FirstNet due to ongoing security concerns.

Hello, Anthony. Although this Galaxy S21 Ultra 5G is unlocked, we would suggest contacting the carrier to ensure their services can be added. Thank you for asking this question. ^Kayla
