How do I get my text messages back to blue?
I am in Canada and I used to send texts to my sister in the US and they used to be blue ( no cost ) but now, out of the blue, they are green ( 75 cents a text !!! ) I went back to my settings and made sure that "iMessage" is on and that "Send as SMS" is off. Still my texts to her are GREEN !!! Please help my iphone 5S as had the lastest update.
