Is it normal for a boyfriend to video call his female bestfriend as well?

Asking for my sister, as she's currently having an argument with her boyfriend regarding this issue where her boyfriend video calls his female bestfriend, when my sister actually told him that they cna just text but why would they need to video call...

Guys, what's your opinions on this?
