I am using this set for last 2 years and had no problem. I am using 2 SIMs in it. Handset is regularly updating its software in routine.
Almost for an year, i started feeling problem.
For outgoing calls, it takes too long in dialing out number and same way, when someone calls me, either of the SIMs is not accessible to the callers though no SIM is used at that time.
It is much irritating for the long time taking in making call or hearing complaints from others that my numbers were not accessible to them.
