All of the major U.S. carriers have plans to deploy mobile 5G networks by early next year, with some early efforts planned for later this year. But the first 5G-ready smartphones won't arrive until 2019.

The big picture: Most of us will be using 4G devices for the foreseeable future.

AT&T, Sprint, T-Mobile and Verizon demoed a jointly developed prototype authentication app at the Mobile World Congress Conference on Wednesday, that uses customer behavior patterns to verify users identity.

Why it matters: While Project Verify may look similar to other apps that use a phone for authentication – Google Authenticator included – cell companies have access to a host of data that app designers, and even phone manufacturers, do not. If it works as intended, Project Verify is a significant step in mobile security.
