Comment 5 for bug 1379850

Jonas: HW we are using is capable of switching active technology used on each SIM slot. There is hw limitation that only one SIM slot can have 3G technology enabled at the time, since phone has only one rf module.

Radio Interface Daemon can alter technologies used on each SIM slot, this operation require modem to reboot in the background, but it is totally possible to do it. We have also successfully tested this with Android build.
