Another option if you are unwilling to search for a provider with adequate service in your area is to have your husband have his cell calls forwarded to a land line inside your home before he comes home. Discontinue the forwarding when he leaves for work.:smileyhappy:
The best choice is to go with a company that has adequate signal in your area.
Since you do not have reliable Internet, other than going with another company with better signal, your only other choice is a signal booster or repeater. I have no experience with these, so I cannot make any recommendations. You can google search verizon signal booster. There are some on Amazon, ubersignal.com, and ebay. Maybe someone else has experience with any of these to chime in.
The way these work is to take a usable signal from outside the home, amplify the signal and re-transmit the signal inside of your home.
