https://community.sony.si/t5/xperia-archive/phone-gets-disconnected/m-p/3403755#M495523 I have z3 dual sim. I use my main sim which is used for voice calls in sim 1 and data sim for Internet in sim 2.<BR /><BR />The first.problem i am facing is that i cannot set sim 1 as the default sim for voice calling.each time i have to select sim.<BR /><BR />The next issue is whenever my voice conversation exceeds more that 2 to 3 minutes, the call gets Disconnected. Sometimes in less than one minute too. I tried to disable the sim 2 or disable mobile network, at this time no issues. The calls goes on. I have faced this issue on my old Samsung dual sim too. Can i get the solution for both problems Sun, 12 Jul 2015 08:40:47 GMT Rachu 2015-07-12T08:40:47Z https://community.sony.si/t5/xperia-archive/phone-gets-disconnected/m-p/3403755#M495523 I have z3 dual sim.
