I got the 450 minute plan right now. Friend & family have my cellphone number. A good deal of them are also on VZW, so the M2M is free. Businesses get my GV number. This allows me to block them if I want to for any reason. It's handy to have a basically 'throw-away' number.
If I were up my minutes where I would then have 'calling circle' numbers I could add my GV number there, but then calls to my VZW people would then cost them minutes, even if it was free for me.
