I am a happy #lineageOS / #Xiaomi #Redmi Note 7 user for years now. Recently, I lost the ability to make outgoing calls. Both simcards (different networks) are OK, tested on other phones. Incoming calls, SMS, and data work just fine. So, my guess is that somehow I blocked outgoing calls at the system level. I spent two days searching for relevant option, to no avail. Any hint how to unlock it will be appreciated. #Android
