IPhone message turned green.

If you and other person are both using iPhone and have enabled Imessaging , that is all your messages are going over Wifi then they will be blue.

If she doesn't have an iPhone or hasn't enabled iMessages then they are green.

Hope this helps

Thank you both. My friend text back to say it got through ok so I suspect from what you say she does not have a smartphone. ??

Agree, if I text to a non iPhone the msg is green rather than iMessage blue. It also happens sometimes if my 3G phone signal drops and I then can’t send iMessages. Check your phone signal and if you can’t see normal signal try turning phone off and on. Also if their iphone was turned off when you sent msg it will show as green on yours.

Mine’s an iPhone, it’s probably different with other phones.

I think the messages are blue if they’re sent to another smartphone and green if it’s not a smartphone Kate
