Here's what's changed at Sprint's prepaid brand:

The following offers have changed for the worse:

The new offer includes 20 GB of hotspot instead of 8 GB and does not require a port-in if activated before 5/7. Video streams at 480p, music at 400 kbps and gaming at 2 mbps.After 5/7 a port-in will be required and the offer ends 7/16.
