fell off the bandwidth

When you place a call on your cell phone and you get the annoying recording saying that "the person you are trying to reach is unavailable at this time, please try your call again later" and then the phone disconnects. Millions of morons are twittering, twattering, texting, sexting, calling, watching videos and otherwise tying up valuable bandwidth so your most important call can't go through.

Dude one- Damn I am trying to reach my babe and all I keep getting is this stupid recording saying to try the call again later.
Dude two- Sounds like you fell off the bandwidth, man.
