Hi team, well i got the same problem on my experia z3 , No Service even the phone read the sim card, i also thought it was a software problem, unfortunately its not, its a hardware, its all about a green small mother board that control the phone network, here is a link for this peace (http://www.ebay.com/itm/Sony-Xperia-Z3-D...), after replacing it, every thing went great :) good luck, Alaa Eddine, Algeria
