Hi,

Did you want to unlock your phone so you can use it with Verizon?

NO not for now. It is locked for ATT at purchase but want to be able to sell or use it for Verizon or Sprint as well as the now Locked ATT

Not any Help from anyone Here on this forum!!!!!!
It just says to use an Unregistered Sim and Verizon was an unregistered sim is why I ask about the Verizon sim.
So if I am on ATT now, do I need to get an unregistered ATT Sim to do the Unlock??????

Unfortunately, you will not be able to use the unlocked AT&T (GSM) phone with Verizon (CDMA) since the carriers use different frequencies.

Hope that helps!

you cannot unlock a mobile from CDMA to GSM
