My Xperia E1 is equipped with two Sim cards.
How does the phone decide which Sim card it prefers for outgoing calls?
I have set Sim 1 as standard, but the size of the two calling button varies randomly every time (button1/button2 larger/smaller than the other, or both the same size).
In addition, when dialling numbers via my car's handsfree kit I would like to place all outgoing calls on the preferred first Sim, but the phone also chooses the Sim freely. How can I define which Sim to use?
