T-Mobile offering new 4-line family plan

Starting Wednesday, T-Mobile will offer customers a new four-line simple choice plan for families.

For $100 a month, families of four will get two-and-a-half times more high-speed data per month.

Each phone line will get 2.5 gigabytes of data, instead of the one gigabyte currently offered.

T-Mobile hopes the move will help it stay competitive on pricing against rival AT&T.
