Last time we reported on Karma, they were just unveiling their new product & service. Now they are ready for primetime as their social mobile hotspot is now ready to launch. Karma uses 4G WiMAX courtesy of Clearwire and Facebook to share access to your hotspot by granting anyone who uses your hotspot, 100MB for you and them. The Karma mobile hotspot itself has a $79 price tag as it has a 8-hour battery life that can be charged via micro-USB, can connect up to 8 devices to it, and comes with 1GB of data.
As far as the data plans go, Karma uses a pay-as-you-go plan as no contracts are involved. You will only get billed when you initially setup and when its time to get more data. Data plans are only $14 per 1GB and can go as many GBs as your wallet can afford. Definitely cheaper than most carrier hotspot plans. Hit the link below to get more info.
