Can't received or make calls at home


    Hello anybody there can help me improve the signal at home. T-Mobile send me cell spot but result still the same. Installed Uniden U60 cell booster still the same. Calls drop, spotty, can't receive or make calls. Chat or text works. My internet is good. T-Mobile map coverage showing my place has fair signal outdoor occasionally indoor but can't make calls. Tried calling outside still not going through. Tmobile tech support tried to call me 3X and drop calls or spotty. I tried Wifi calling even worst. Any recommendations out there. Thank you Arnold
