Customers on Karma's pay-as-you-go Refuel plan ($15 per gigabyte) will have to pay $15 a month for premium features, while it'll cost people using its Pulse subscription plans (starting at $40 a month for 5GB) an additional $5 a month. Refuel users can try out the premium features for $10 for their first month, while Pulse members will get it free for one month. And if you're just getting started, you'll have to pick up the company's $149 Karma Go hotspot as well.

Karma's private network feature works just like any other hotspot: It'll let you secure your network with a password, allowing only the people you want to join in. Naturally, you'll be able to change the name of your hotspot, and you can even add emojis to the name (something not every hotspot and router supports). Another plus to having a private Karma network? You can actually connect other devices that don't have web browsers (think set-top boxes, wearables and the like).

Of course, with a private network you won't be able to take advantage of the free credit Karma offers when people connect to your open network. Currently, Refuel customers get an extra 100MB of data whenever someone else connects to their hotspot, and Pulse members get $1 off their next bill. It's a shame to see Karma back away from its core concept, but it also makes sense. Sometimes you just need to have more control.
