SMS has a 160 character limit, and Twitter was originally supposed to be SMS driven. I personally don't know anyone who has ever Tweeted via SMS though, or whether that is still even possible.
On an old iPhone with just basic speech to text abilities I would sometimes use Bluetooth to "text twitter ..." and that worked. (Nowadays we got our Siris and Cortanas and direct app integration, but that "text twitter" is still sometimes a more reliable voice trigger than "tweet".)
I still often turn on SMS notifications for accounts I want to specifically hear from or events I'm attending.
