pu1. Dial-in confirmation is a supplementary service, so you need to sign up
To sign up, you can call the carrier's customer center 114 and apply for it

pu4. The phone confirmation service on the phone has different names for each carrier, but SK Telecom calls it a goalkeeper and KT Olle calls it a catch call

pu5. You can sign up for additional services
When you sign up, if you get a call while you're on the phone, you text someone to tell you that you've been on the phone
Or even if your phone is turned off, you can tell me where and how many calls you received by text message when you turned it on
