Not my last purchase but thought I would join in.
$20 a month for 300MB of data that I don't use because I have wifi everywhere. A data plan is required and that is the lowest option. And $5 for 200 SMS. The minutes are rollover. I don't talk very much so I never worry about going over. Is a Lumia 920 for $99 and I got a second one for free, plus two free wireless chargers. The monthly bill is about $400 from ATT with Uverse HD TV and 12Mb internet combined in one bill.
I do think the Iphone 5 is great but I would never get one. My dad has the 4S and it is worse than the 920.
