    Radio waves, tho…

    The first mobile telephone was in the 40s using radio… that’s plenty of time for more niche adaptations… not saying they did happen, only that they could have. The battery pack or generator would be huge (which is why they were in cars).

    But ring a number for a bum jingle, why not?
