Do All iPhone 5s have a Sim Card slot?

Shopping for an iPhone 5 Online i have been seeing
iPhone 5 for Verizon Unlocked and
iPhone 5 for Sprint Unlocked
The iPhone 4 That had a Sim Card Slot was the AT&T only and i'm wondering if Verizon and Sprint allow Sim Cards now?

All iPhones from the 4s to the 5 all have SIM card slots, and are considered world phones, they will work on any GSM or CDMA networks.

I guess yeah

The iPhone 4 was either a GSM or CDMA device. However the iPhone 4S & 5 are GSM/CDMA phones. Doesn't mean though that ones bought from Sprint/Verizon would instantly work on AT&T with their SIM cards, though the 5 from Verizon is unlocked out the box.

  • Sprint Iphone 5 sim card slot? I have the 16 gb iPhone 5 from sprint and i realized that the phone still has the sim card slot. Does this mean that the phone can be unlocked to be used with at&t or t-mobile? Or is it unlocked already?
  • Iphone does not have a sim card slot? I bought an I phone 4 by Verizon. I have T Mobile so my friend would have been able to unlock it and what not. The problem is, it does NOT have a sim card slot AT ALL. Is there any way i can use the phone without selling it? *Maybe go by the Verizon or T Mobile store? *seriously I need help with this. Because I really want to use it and if I can't at all please help me. Or let me know.
