kiwitrc:NealR: @JoeBlogs, not sure where you got our stats from. When I look, the success rate is greater than 99.7% (>1/300), not 97% (1/30) as you describe. The majority of these failures are because of invalid numbers.

The figure I give is off the cuff from an engineer and is nothing to do with users sending the message to the wrong number. Also note the figure is when any form of queue is activated on the text message rather than it being sent immediately (this could last 5 seconds or an entire day). Unless of course you maintain part of VF's infrastructure... ?
