Our friends at Sprint Feed have procured evidence suggesting Sprint will begin the change to tiered data for some of their data users starting November 13th. The changes affect mobile broadband (dedicated data cards and hotspot devices) as well as mobile hotspot (USB or WiFi tethering with phone) customers. It gets rid of 3G and 4G unlimited data, giving you 3GB, 5GB or 10GB of data usage combined per month before overages apply. The prices for those plans are $35, $50 and $80, respectively. All that’s left in the land of unlimited on the Now Network is smartphone data. What’s the over/under that those will soon share similar fates?
