Most carriers shy away from offering LTE on its prepaid plans, but Sprint is diving right in by making it available on its first Virgin Mobile device. The network will take advantage of Sprint's Spark service, which will offer tri-band LTE support at faster speeds on the company's Broadband2Go plans. The first device to leverage it is the Netgear Mingle, which is essentially a red version of Sprint's Zing (pictured above). You can get the fast service at a cost of $5 per day, or you can choose monthly plans of 1.5GB for $25 or 6GB fof $55. Additionally, Sprint announced that it will launch Spark in six more cities: Dallas, Austin, Fort Worth, San Antonio, Houston and Fort Lauderdale.
