I have google voice phone number... on my old S3 sprint. I will pay to transfer the phone sprint number to google voice. cancel sprint. I could keep this setup on the S3. and have 2 phones.. but I don't want to carry 2 phones. I have a new Note3 on ATT. 3GB data limit. with it's own phone number from ATT.. it is for work. question: can I load Google voice and Talkatone.. on my new Note3? and Voice/talkatone not interfere with my ATT phone calls and messages? two fully separate phones services (phone calls and texting).. but housed in one device. example: friends and family can can call or text to me on old-number.. the Voice/talkatone apps will ring or notify me on the Note3 when work calls the new-ATT-number.. the Note3's dialer and text app will ring or notify me. is this how it works?
