Loss of signal, but WiFi works

Hi, I have an iphone 4 with ios 7.0.2... My problem is that the phone while it is running normally, suddenly loses signal, and stays on "Searching...". The curious thing is that the WiFi still works perfectly, so I think it isn't a hardware problem of the antenna, which I also already tried to clean up... I also tried a full reset with the DFU mode, but nothing... What can I try? Thanks to all!

Hello... I replaced the antenna, but the problem persists... The signal strenght is between -69 and -91 (occasionally)... it is often -77... But sometimes loses the signal... A friend told me that the component should settle, I mounted it on later this afternoon ... Now the signal is excellent, and is apparently stable.... but until this afternoon the signal disappeared continuosly... Now I see if using the phone it loses signal again... It may be that the parts had to settle?

The RSSI is normal, maybe the logic board is defective, or a software or carrier problem. Go to diagnostic & usage to see if there are any crash logs that might help
