Abstract: For example, Verizon Wireless and Sprint PCS use a digital technology called code-division multiple access to transmit phone calls. As a result, the two carriers' phones can't be used on networks run by AT&T Wireless Services Inc., Cingular Wireless and T- Mobile USA Inc., which use a competing standard called GSM, or global system for mobile communications.

Even so, it isn't illegal for customers to unlock their phones themselves, and that's where outfits such as San Diego-based Mobile Electronics Warehouse (MOEW) come in. "A very important factor in this is consumer awareness," Han notes. "Last year we had local number portability, which most customers are now aware of. And now we are seeing an increasing consumer awareness of phone portability."
