same here . don't understand it either .. my question are ? i get t mobile to change my data plan to the $10 , they text me a data plan info do i have to add some number to my phone ?? if i get the T zones which i just called them and they say its free on some phone but they can send me a data text . Will i get full access to the internet or they will charge me for what i use. its free but they told me its limited access .? does it matter cuz our phones are so great that it bypasses that .?
