Does data transmitted wirelessly have mass, is it visible on any spectrum? Please explaing why for either yes or no, I’m confused.

You can send transmissions via visible light, though generally people don’t because a rapidly pulsing 600nm band signal (orangish red light) from a tower would annoy a lot of people and be stopped by pretty thin barriers. It also isn’t quite as convent or easy to make directional as a microwave transmission.
Light has no resting mass, so the signals aren’t heavy, even as whole movies, novels, cat pictures and naughty text messages fly past you all day.
Though not wireless old toslink audio cables used fiber optic cable to carry visible light. You could see the red light blinking when in operation, ‘seeing’ the data.
