Somehow it knows and the send button will remain dimmed, which means you cannot send the message.
From: Arnold Schmidt Sent: Tuesday, February 05, 2013 8:05 PM To: viphone@googlegroups.com Subject: IMessage Versus Text Message Question I understand that an iMessage can have an unlimited number of characters, but only can be used between Apple devices. A text message allegedly only can have 160 characters. If I have iMessage turned on,how does my phone know whether the recipient is using an Apple device, or not, to which it is sending my iMessage? And if I send an iMessage to a non Apple device, I guess it is delivered as a regular text message. Does it just cut off after 160 characters? I do intend to buy the new book, published by National Braille Press, about iMessaging. Thanks for any information.
