No offense meant and it may just be due to imprecise wording, but this is plain wrong.
Toggling data off forces a disconnect _from the data network_ but the phones remains attached to what ever cellular network it uses for voice and SMS so you can still make and receive voice calls and SMS. Anything data, on the other hand, will have to go through WiFi if available.
