You're in luck, Lourdes, as Nextel offers second-line service on handsets such as the Motorola i580. The handy service allows you to add a second line with a different phone number to a phone--perfect for anyone who wants separate digits for personal and business use. Nextel was one of the first U.S. carriers to offer the functionality. You'll need to sign up for a second service plan, but you can have separate ring tones, separate billing statements, and even phone numbers with different area codes. Hopefully, we'll see this service from other carriers soon.
