What’s the difference between blue and green text messages on iPhone?
I’ve read that green messages are sent via standard SMS text messaging (and text message rates may apply), and that blue messages are sent via iMessage (Apple’s iOS messaging - essentially free messaging between iPhone users). Am I wrong? I feel that there must be something else to it. For example, why is it that a thread to the same person (say my daughter on her iPhone), has both green and blue messages? I mean, she’s on an iPhone, so why doesn’t it use iMessage all of the time?
