what is local number portability (lnp)?

Local number portability lets you "port" (transfer) an existing telephone number from your current phone service provider to another carrier. This means you can keep your current phone number when you change your wireless service to Cricket, as long as Cricket provides service in the same location as your current provider. There are three types of portability:

1.    Wireless to wireless
2.    Wireline to wireless (transferring your home phone to your cell phone or vice versa)
3.    Wireline to wireline
