I have had my Novatel USB760 since August and have had no problems with it., EVDO RSSI usually in the -80s. All of a sudden a few days ago it started fluctuating from the -90s up to -117 and switching from mobile broadband to national access. When it is at -117 it is practically unusable. I called and reported the problem yesterday morning and got a call back today saying that "network changes" were made, the information about which was "proprietary", that I am in a questionable area (which I was not when I signed up) and that they cannot guaratee my service. They said I can get out my contract without a penalty or get a free upgrade to 4G when it becomes available (???). That's a great offer, but it doesn't help me any, I work from home and need decent internet. I left Hughesnet because it had become impossibly slow most of the time that I needed it.
I want to understand why a "network change" would be made that would give me less signal out here and if there is anything that can be done about it.
Verizon customer service may not tell you if you have exceeded your GB threshold, which in turn can affect your service. I have an unlimited plan, and over the holidays exceeded some invisible threshold they have for unlimited customers. As I called customer support, trying to determine why my service was so slow, I found on other posts this practice.
