My cell service in my home is horrible - we have iPhone 5s. Even friends that come over can't make calls. Most of them also own an iPhone 5S. We have to place it by windows and that doesn't even help. Always at 1 bar and most of the time it doesn't even ring. I drop calls all the time too. And it's even worse when it's cloudy. ha! I've been researching signal boosters, network extenders and wifi calling, but I don't feel like handing out more money when I'm already paying for a service I'm not receiving. Anyone have any advice for a solution? My zipcode is 06073. According to the map, we have excellent coverage.
