Re: Xperia T2 Ultra / T2 Ultra Dual Lollipop issues and feedback

Hi, I have Sony Xperia T2 Ultra Dual and if I'm using only one sim card with the device it's working fine but as soon as I switch a second one on (inserted in the other sim slot but not enabled most ot the time), almost all calls get disconnected/dropped and the sim used for making/receiving the call becomes unavailable (empty bar/no service - looks like it's being disabled, although it's not). I've already used PC Companion to repair/reinstall it, to no avail. Please help, how can i fix this? Many thanks in advance!
