Text-only iMessages often get through cruise Wi-Fi without a package because they ride Apple's push channel. Why photos don't, and why it's hard to block.
Switch a Royal Caribbean Samsung cabin TV to HDMI using only the power button under the screen, so you can use a Fire TV Stick without a universal remote.
