This is actually on behalf of my wife; so far I haven't experienced this problem, but... My wife and I both have iPhone 5S with the most recent iOS7 update from last week. We both have iMessage DISABLED because we're stingy with data but we get unlimited texting. She's having trouble receiving text messages that originate with iMessage. They'll arrive hours, sometimes days, late. And sometimes they show up on her MacBookPro -- despite her never activating iMessage through there! -- but she doesn't want that, she wants them all to show up on her iPhone and in a timely manner but without enabling iMessage. Now, I've had ZERO problems with iMessage, and I don't receive text messages via my iMac with Mavericks. I checked our settings, we're both set up the same way. What all do I need to check?
