Your side of the call travels over the internet, so a steady Wi-Fi or wired connection gives the cleanest audio and avoids using your mobile data.
The rate is the same around the clock, but reaching someone on the first try avoids wasted call-backs. A quick glance at their local time means you connect once and talk.
