What problems are you having that you think you need a tech?
*I am not a Hughesnet employee or representative. This is a customer-to-customer tech support community, and I am a customer.
Anytime a tech is sent it costs to do so. The time, mostly, as in travel time and work time, and the cost of materials. This type of tech visit is for nonessential, non warranty work. It's a flat fee.
I've had service for nearly 14 years and it would cost me $125, as well. Again, it's nonessential, non warranty work.
