I just started a new job and although the location is well within 4G signal area (Austin, TX) I get absolutely no service while inside the relatively small 2 story commercial building. My previous workplace in Austin had much bigger buildings and I never had issue with getting service signal.
Is there anything Verizon can do to increase the signal strength within this building? This is a major employer in Austin (Samsung, the building has roughly 300 employees).
Don't count on it. There are many many threads on the forum that address this. You will not get anything from VZW as there is no guarantee of service inside of any structure. Talk to your employer and ask them to install repeaters or network extenders.
