That's not my understanding, or wikipedia's [1] understanding, of the term. Phishing is the general category of tricking people into telling you things they shouldn't. Email phishing, voice phishing (vishing), sms phising, and so on are subcategories.

Etymologically "phreak" and "fishing" both have nothing to do with email, "phreak" is "phone freak" and I believe it originally described messing with the tones that controlled the telephone system...
