funny ive been able to imessage for free on southwest by connceting to the wifi and not paying. Have they blocked the imessage ports after discovering this trick?
shame lol.
Haven't done this on Southwest, but I definitely get iMessages through some of the underground wifi signals in the subway here in NYC — the networks themselves often are free but require jumping through really irritating hoops like watching videos and crap like that. I never bother to log in, but it's nice to get messages in and out.
