iMessage goes to stranger instead of my contact
For some reason, when I try to text my friend while iMessage is activated on my phone, the message goes to a complete stranger (who is getting annoyed with me). If I SMS to the same number, it goes through to my friend just as it should. My friend does not have an iOS device. I really don't want to turn iMessage off on my phone, because most of the people I know have iPhones and I like the iMessage features. I'm finding that I have to turn iMessages on and off throughout the day just to text my friend (which is a pain).
What could be causing the iMessage to go to the wrong person? I'm sending to the exact same phone number each time. Is there a way within the iMessage app to designate whether I want the text to be send as SMS without turning iMessage on and off in the settings?
Thanks for the help!
