After announcing its Black Friday deals on smartphones and tablets earlier this month, Sprint today followed up by revealing a Black Friday deal on smartphone plans.

Starting today, November 23, Sprint is offering three free lines of service. To qualify, you’ll need to switch at least one line to Sprint and sign up for an Unlimited Freedom plan with AutoPay. You can then get one line for $60 per month, two lines for $100, then your third, fourth, and fifth lines for free.

The third, fourth, and fifth lines will be free until January 31, 2018. After that date, they’ll cost $30 per month per line. Each line includes unlimited talk, text, and data.

This three lines free offer will be available from November 23 through December 1, so you’ve got some time to take advantage of it.
