My Galaxy S4 i545 will Not connect to cellular signal/service at all, Nothing, No service whatsoever. I called Samsung, Tech had me do a Hard Key Reset, That did not help a thing, except for me to loose everything I had on device, back to factory default setup (like a brand new one). Anyone else have or have had this problem ? If so, what did you do to fix it? My wife has the exact same device (different color), and it works fine. Wifi connection to my wireless broadband router works fine. Need Help with this issue before I Slam this Brand New Black Mist 16gb S4 up against a Wall.
