Virgin Mobile began sending out text messages to high data consuming customers to warn them of their plans to implement data speed reductions in March. This comes as no surprise as Virgin Mobile actually considered throttling back in September, but for some reason decided to put the idea on hold. This time, it’s for real, and they plan on starting on March 23rd. If you’re a Virgin Mobile USA customer and use over 2.5GB of data in a month, expect your speeds to start slowing down (if that’s even possible).
