Even with predictive text, writing a message on a mobile phone can be a pain, so I've been trying out SMS Global and am quite impressed. I'll have a form set up soon so that people can SMS me if they don't know my number.
I also had a surprisingly fast experience with their customer service:
3:54pm - I emailed them about the contact search tool, which only worked for exact matches. 4:12pm - Reply stating that they'd passed it onto the developers and it was corrected immediately.
