Yes, all 3 are Quad-band or world phones. Here's the difference:
L2 - Basic phone with Bluetooth and Push-to-talk.
L6 - As well as Bluetooth and Push-to-talk, the L6 has a camera and video capture.
L7 - Has Bluetooth and camera feature, but NO Push-to-talk. The main feature is the MP3 player on this one with I-Tunes software. It also has expandable memory and fits upwards of 1000 songs.
If you ask me... I would prefer the L7 because it has the most features... but that really depends upon what you want. Hope that helps
