Boost Mobile is making a big change to its rate plans.

Starting today, Boost Mobile’s rate plans include taxes and fees, making it easier for customers to know exactly what they’ll be paying for their service. New customers can get a plan with taxes and fees included today, and existing customers will see taxes and fees included with their next monthly payment after September 8th.

Boost also notes that’s running a limited time promotion that’ll get customers four lines with unlimited talk, text, and data for $100 per month. With this plan, video streaming is limited to 480p resolution, music is limited to 500kbps, and streaming games are limited to 2Mbps.

This four lines for $100 promo will run through November 2nd, 2017.
