I figure very few may be impacted by this, but given my own experience with ATT Next, I thought I would highlight that ATT does not allow you to provision an alternative carrier's eSIM while the new phone is under a Next contract. Only at the point of the iPhone being unlocked will they allow an eSim to be activated for an alternative additional carrier. I say this having petitioned ATT to unlock my iPhone early given that I had been an ATT customer for nearly 30 years and live in a rural state where they have uneven coverage. They refused and I no longer get phones from them. YMMV.
