It looks like HughesNet is trying their best to keep pace with new competition from Verizon's fixed LTE service Home Fusion, which offers users service in $60 (10 GB cap), $90 (20 GB cap) and $120 (30 GB plan) flavors.
Our service didn't work for weeks at a time. Techs came and went without a solution, yet, $80.00 was taken out of our account monthly. They wouldn't let us out of our contract, we didn't have internet connection, and their customer service was appalling. If you need to access the net, don't use this company. Go to EXEDE or anything other than HughesNet.
