Galaxy S4 Recognizes Sim but says no network

Hi, I have a galaxy s4 that is unlocked. It recognizes the sim card but won't give me signal or service. I have been having great signal until today. Today I disassembled the phone and reassembled properly. If you know any tips or trucks I could try it would be much appreciated. Thanks.

u might have damaged the antenna wire so replace the wire that goes from the charging port to the motherboard right next to the lcd cable
