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?
Sprint Iphone 5 sim card slot?
It is easy to jailbreak it.
I read online from CNET that "Sprint will unlock the global SIM if you've been a customer for 90 days and are in good financial standing (your bill is paid). "
Short answer: No. Even though most devices by CDMA carriers (incl. Verizon and Sprint) do have SIM Card slots, they only enable you to use the device with GSM carriers abroad.US GSM carriers like AT&T and T-Mobile are blocked from those devices, even if unlocked.
