Can I manually reset Cellular network configuration without losing WiFi passwords?
I know I can reset network configuration, which: 1) resets cellular data, but 2) also removes all wifi passwords.
Can I do #1 without #2?
I mean to try that as a solution to No celullar signal after replacing battery, if not updating iOS
Solution 1:
This looks like a new feature, at least in iOS 15.1 you already have this option: Settings > Mobile Data > Mobile Data Network > Reset Settings
In previous iOS 14 was in Settings > General > Reset > Reset Network Settings, but as you said unfortunately was removing the wifi passwords.
