Using a bluetooth earpiece can the DTEK50 call a number from the contacts list by a simple voice command, this is what i miss from my last bb phone. My current samsung will not allow me to do this simple task and will reply ' i cant find a network connection'. So it looks like i need mobile data or wifi on for it to look up my command first. I dont like talking on the phone on blue tooth whilst driving but this is a real handy feature to use if needed. Thanks in advance.
