Boost Mobile, a pre-paid subsidiary of Sprint in the US, will begin throttling data speeds January 20 for users who have transferred more than 2.5GB in a billing period. Boost will send out a warning text message at 85 percent of 2.5GB, and then will throttle speeds to 256kbps after the threshold is passed.
This isn't the first unlimited data plan provider to begin throttling connections. Boost says that the throttling will only affect a small portion of its customer base, though some vocal customers are upset with the change. Boost has tried to reassure people that 2.5GB is a lot of data, likening it to 90,000 e-mails, 91 hours of streamed music, or 20 hours of video clips.
If you're on Boost and use a lot of data, be ready to get throttled come January 20.
