As truculent noted, the friction involved in doing any of those things is pretty much enough to just not do anything at all. Aside from sending SMS messages (or I guess, WhatsApp messages, once you manage to actually login to WhatsApp), the whole process is so painful, it reminds me why I haven't owned a T9 phone since the Motorola Razr -- and why I ultimately moved from that device to a BlackBerry (and then to an iPhone). I genuinely have no idea how I used to send so many text messages in high school and college.
