I am using S3 and will switch to Note 3 when it gets here. I am also on Sprint. I am starting a new job and need group texting. I have my GV integrated with S3 so my GV# is the number everyone uses now. I need to switch to my Sprint #. I need to contact old clients from my GV#. 3 years ago on my Iphone I used an app call GV+ that would allow me to choose on each call or text which phone # I wanted to use. Is there a good android option? Or any way to make GV group text? I am rooted if that helps. Thanks for the help.
