So my iphone 5 drops calls at my house all the time. I have had it replaced and had new Sim put in. still does it. about 30% of calls are dropped. however i have a blackberry for work on same network and its fine and my wifes 4 doesnt drop calls either. I'm up for a new phone and want a 5S, but since the majority of the phone is the same, what are the chances it will drop calls at my house? it would suck to have to change brands of phone due to this. i live in a regular city and it even seems like it drops when im standing outside my house as well. Think its dumb to get a 5S, or does anyone think the dropped calls will go away.
