Inside my office, barely works. Outside is OK.
The fix is to get one of those cell phone indoor boosters if your carrier can't address coverage like this. You see them from Verizon and other carriers to fix indoor issues.
I have a Samsung galaxy S duos S7562 dual SIM mobile phone. Off late i am facing one peculiar problem. In my office, i am not able to make or receive any call through SIM1(It shows the message call ended after calling any number), where as i can make normal call through SIM2. The network of SIM 1 is OK. When i go outside of my office and make any call through SIM1, i am able to make call. But at the same time when i remove the SIM1 and put it on my old Nokia mobile, i am able to call and receive in my office also. Also my colleagues in the office are able to make call through the same Service provider as my SIM1 from the office itself. But i am not facing the problem in SIM2. I have tried to interchange the SIM1 with SIM2 also, but no improvements found. What could be the problem? Kindly suggest some solution as my SIM1 is my main no. and most of the time i spend in office.
