Why isn't any of my contacts' updates being sent to my mobile as set up?

why isn't any of my contacts updates being sent to my mobile as set up?

I have it set up to send updates to my cell phone, it is registered, confirmed and I can post to twitter from my cell, but twitter SENDS ME NOTHING! Not even the nudge to update every 24 hours as it is set up to.

I have scoured each setting for any possible reason, I removed my cell phone and re-set it up, and still nothing.
 
sad I’m frustrated
