I live in the metro area of MN. I had a 3G modem and a Samsung Convoy phone and both worked almost flawlessly for over 3 years. After the change to 4G my modem connection would often drop from 4G to 3G or I would lose it completely. I was able to solve this problem by switching to a Jetpack 4510L modem with an external antenna and locating it in the best reception spot in the house. Reception went from barely one bar to two or three.
I recently got a Samsung S4 with the same problem of it dropping from 3G to 4G. I can deal with that by connecting the phone to my modem via WiFi. However calls frequently "break up" or are dropped.
I called Verizon service and got a rep with a strong Indian accent tell me that "you are in a marginal service area". I asked him it that meant if I kept paying my bill on time I would continue to receive marginal wireless service. He did not respond.
My question is how can I improve the reception on the phone so I could use it in the house. I connected to the modem via WiFi but that does not seem to do anything for voice on the phone. Is there a setting to provide voice over the modems connection? It is difficult to believe that the change from 4G to 3G actually reduced service in my area. I noticed that the problem occurs when the phone icons show the 4G changing to 3G then 1X
