Sprint's Boost Mobile has notified dealers of a new 4 lines for $100 family plan promotion that's starting tomorrow February 14. To get the deal you have to port at least one line from a non-Sprint based operator. The other three lines have to be either port-ins or new activations. Two or three lines cost the same $100 as four. You can add a fifth line for $30 extra. The first line is eligible for a $5/month discount for using auto pay.
All lines get all the same features as Boost's regular Unlimited Gigs plan that costs $50 for the first line and $30 for each additional line and is available to new and old customers without the port-in requirement. Those features include:
Unlimited on-network domestic voice minutes and messaging.
Unlimited, unthrottled data with the following restrictions: all video streaming is degraded to 480p resolution, all audio streaming is restricted to 500Kbps, all online gaming data is throttled to 2 Mbps, and hotspot, VPN and P2P data is throttled to 2g speeds after 8 GB/month. After 23 GB/month data performance will be deprioritized when the network is congested.
50 minutes/month of domestic voice roaming.
The new family plan promotion is available at Boost dealers from Feb 14 until March 14, 2017.
