After pulling the plug on its "unlimited 4G" deal, Sprint is now unveiling altogether new 3G / 4G plans for its mobile broadband services. Boasting "more data at a lower price than competitors," the carrier's upper tier is now $79.99 for 12GB monthly (vs. $80 for 10GB on Verizon) and $49.99 for 6GB monthly (vs. $50 for 5GB on either AT&T or Verizon). The new plans are applicable to dedicated mobile hotspots, USB modems, tablets, netbooks, and notebooks. 

Additionally, Sprint is offering a $34.99 for 3GB tier for tablets and (most) 3G / 4G hotspots and a $19.99 for 1GB monthly plan for tablets only. Now this is where things start looking less like a deal, as both AT&T and Verizon offer more competitive lower-tier data plans for slates — 2GB for $25 on Ma Bell and for $30 on Big Red. As is always the case, the more you're willing to invest monthly, to better the deal. For all of Sprint's new data deals, the overage is $0.05 per MB, which amounts to a whopping $50 per 1GB over. Keep that in mind when making your choice.
