Its right there, chief
Personally, I don't know how they do it...I mean if you "underutilize" your minutes for just one month, you pretty much cannot go over. My wife informed me yesterday that i currently have about 4000+ rollover minutes.
And After being a customer on Sprint, Verizon and T-Mobile in the past, there is no way I could ever consider a voice plan where I don't get my minutes back. Its just archaic and inconceivable to me (yes, personal opinion) that if i only use 700mins out of a thousand, I don't get 1000+300 the next month.
Now...I will say that free T-mob hotspot access is pretty nice...but i've been giving them $30/month for this for awhile anyway...because they are everywhere i travel.
What gets me tho, is well...what kind of incomes are we talking about here for folks that plan to pay $600 for a phone, but only have $30 to spend to talk on it?
And you know, looking at it from ATTs POV...sure they could sell it with no data plan, and you know, charge like $5 meg if you even try it. And you know people will piss and moan when they get that first bill because they HAD to try it "just this one time" blah blah blah.
Anyway, I guess you aren't getting an iPhone, because you aren't getting 1000 mins and 'data forever' from att for 30 bucks
More for everyone else, I suppose
Oh yeah.
All of those cases are "meh". Personally, unless I have to, I'm not planning on removing my phone from whatever pocket or whatever its in; my ego is well-formed enough where i don't need the universe to gawk at my phone
