Karma just update their pay model adding an unlimited data plan for $50 a month for those of you who may want to use it more. You can check that out over at Karma’s official page or Engadget did a write up about it.

I have been using this for a while and it seems to be a great personal hotspot or a backup when you really need it.

To save an aditional $10 off your purchase you can use this code

Hope everything works out for you
