Hello, For about the past 3 years, for some god known reason, my house blocks incoming calls and/or text messages at random. I always have 3-5 bars, but if you try to make a call, it will sometimes just sit there for a good amount of time before it actually starts to dial. Other times, I won't recieve a call or a text. The person on the other end either had it ring multiple times or the text was sent X minutes ago before I finally recieve it. Does anyone know what my problem is? I feel like if I have 3-5 bars, I shouldn't be having a problem. What could be blocking this? Is there a device I could use to track down some signal blocker? I know there is extenders or cell reception strengtheners, but... I don't think that's the problem. As you can imagine, it's very frustrating.
