Running Lineage on AT&T has drastically reduced the number of compatible phones due to the hard requirement for VoLTE (voice over LTE) on a small set of authorized phones. I had just upgraded my OnePlus 3 to a 5 when this was announced, so I purchased a Pixel 3a XL by the deadline (which fortunately has VoLTE in AOSP). I moved my phone to Verizon for a few reasons, but Lineage struggles with VoLTE and this is a big reason for old phones in a drawer.
