is there a sim card in an i phone model md146LL
if it is an iPhoen 4 with AT&T, yes
if it is with Verizon or Sprint, no
Amazon.com has it (link), and it is described as a Verizon phone, so no SIM slot.
Ironically, they do not display the side of the phone that would have a SIM Card Tray if it was a GSM device lol
