Just as a question, how much notice do I have to give Hughes that I want to terminate service and stop billing if I can find another ISP?
No notice really ...
Cancelations have to be done by the account holder over the phone.
Usually a cancelation become effective at the end of the current billing cycle although you can demand an immediate cancellation.
Unless you have purchased your equipment outright the Modem, Power supply and the "radio" mounted on the end of the dish arm must be returned to Hughes in the pre-paid return kit that will be sent out when the cancelation becomes effective.
Be aware of the following:
The equipment must be returned within 45 days of effective cancelation or an Unreturned Equipment Fee may be charged
A Early Termination Fee may be charged if you have not completed your 24 month service commitment.
