"AT&T unlocked" refers to a mobile device that has been released from AT&T's network restrictions, allowing it to be used with other carriers. This typically means the phone can accept SIM cards from different networks, enabling users to switch carriers without being tied to AT&T. Devices are usually unlocked after they are fully paid off and meet certain eligibility criteria set by AT&T. An unlocked phone offers greater flexibility for international travel and changing service providers.

an unlocked phone could mean one of two things. One, the phone belongs to a GSM carrier (like T-mobile, or AT&T) but being that it is unlocked you can use it with any carrier that requires a sim card. The second can mean that it is a CDMA phone with GSM capabilities normally on a Sprint or Verizon Global phone meaning it is a CDMA phone with a sim card slot and as long as it is unlocked it can be used also with any other carrier that requires a sim card. However it has nothing to do with what is on the actual phone, so even if it says T-mobile it can still be an unlocked phone.
