There are two ways that you can pay for Karma Go, meaning two ways you can be charged.
If you have a Pulse account, you are charged each month for the option you choose. ($40, $75 or $140)
And, we also have an Auto Refill feature for Refuel. This lets you select a specific amount of data that automatically gets added to your account, should you run low.
Once you get a payment method saved to your account, you can set up Auto Refill in your dashboard.
