first of all, i don't know what you're talking about. there is no such thing where it's free to talk to sprint people on monday and tmobile people on tuesday, etc. nothing like that exists. i don't know exactly what plan you have but most plans have free night and weekends, so you can talk to anybody for free on saturday and sunday. also, free nights, which are usually from 9pm to 6am i believe. most likely you can talk to people on verizon for free any time. you should go to a verizon store and they'll be able to tell you exactly when you can talk to people for free.
