I have an iPhone 12 Pro Max with a physical and eSIM (both on AT&T in the US). On most nights (not all) between 3am-6am I lose service on both lines. I'm still connected to WiFi and Bluetooth and this never happens at any other time and my phone is always in the same place (my bedside table) when it happens (it sits there during the day with no issue).
A simple restart of the phone fixes the issue but I'm curious as to why this happens and if there's a solution.
