I use two sim one for calling and an other for data. If I make a phone call I can choose witch sim card handles it. There is a 9 seconds delay time for the last used sim If I don't choose the phone call starts by the last sim after 9 seconds. I use only one sim card for calling and It would be good If I can decraise the waiting time to only 1 second or less maybe to zero if possible. Where can I change this?
