The difference between a locked and an unlocked phone is that a locked device has a software code on it that prevents you from taking a GSM-based device and using it on another GSM carrier's network.nce a device is unlocked, you can pop out the SIM card and put in a different SIM from another GSM operator and get service. Remember that this issue of locked and unlocked phones today is really only relevant when you're talking about devices made for GSM networks.
For example, if AT&T paid for the phone, AT&T would lock it so it could only be used on AT&T and not T-Mobile. This lock is called by several names including: Sub Lock or SPC Lock or Sim Lock. Now that you know why the cell phones are locked, I will discuss how to tell if your cell phone is locked or unlocked. First, you must determine if your phone is a GSM phone or a CDMA phone. This is easy to tell, if the phone uses a sim card (a small piece of plastic that you put in the phone, see picture below), it is GSM, if it doesn't, it is CDMA.
