Don't own an iPhone, has a Mac book... please help
I just got a Mac book and I don't have an iPhone so i don't have a phone number. My husband has an iPhone and and iPad. I would like to be able to send him messages from my laptop. how do I do this?
Also every time I log into iMessages, it opens for like 15 seconds then closes while telling me to log back in. I have never owned Apple products in my life. Please help! Thank you.
