The commercial is advertising falsely also I have heard from reading here that after three months the bill increases..
Just like on the HughesNet website, the TV commercials have fine print. As well, the HughesNet Subscriber Agreement is available for anyone on the net to read, and every prospective customer should read that agreement before signing up for service. Along the same lines, everyone should thoroughly research HughesNet before making the decision of signing up for it, especially considering the fact that it comes with a 24 month commitment. IOW, know what you're buying before you buy it.
There is no bill increase after three months unless you signed up through a reseller that offered such. Initial plan discounts with HughesNet proper, if they are offered at the given time, are for either 12 months or 24 months, and such is indicated on the website and/or during the sales call.
