Answer 1

Smartphones can do long-range communication using cellular networks or the internet, but walkie-talkies use radio frequencies for short-range communication without the need of a network. You can use a smartphone like a walkie-talkie with a special app, but it might have limitations like distance, security, and battery. Also, smartphones are not optimized for this specific purpose like walkie-talkies are.
