STI 15 Signal problem

[giatin67]

Hi, a few months ago my sti15 has problems with telephone signal that is significantly lowered even without call. During the conversations of 2 minutes releases the network signal and the display cho marks can make emergency calls only (other phones have full field) and then recover! Not a problem manager. I sent the phone for repair and I have reset the device but unfortunately sometimes the probleme is still verifcation. What can I do? THANK Gianni

I suggest a new SIM, as this could be the SIM that is causing the drop on signal within the device.

Let me know how you get on.
