I live in southwest Florida between Sarasota and Ft.Myers. This is my first smart phone before that I had on old flip phone on the nextel network. I know that Sprint is working to put towers up and get the lte network working. My question is inside my house and pretty much a five mile radius I have absolutely no signal and if I do it's normally one bar no 3g or even roaming. If it wasn't for wifi at my house I would be totally be screwed is there anything I can do to my phone to help improve my signal or take it in to a sprint store and have them do something to help with this issue?
