I had to use this phone in the year 2007.Now a days this is very old model phone.When i was use it then i have faced the same problem.Then Customer care support of siemens company said that it is problem of network ic of the phone.

I guss the signal is terrible at home ,many cell phone do also have this problem ,better or worse depends on the kind of your cell phone.

My cell phone is old. It's Siemens A56, made in Germany, with "Cingular" on the front. When I'm at home, "Network search" used to show up only once per a few days. Now it's about 50% of the time. I took out the battery and SIM card and blew air on them to clean away dust. It made no difference. I like this phone, very small in spite of limited functionality. Any suggestion to boost its capability to receive signals? It works fine outdoors. Thanks.
