Now that cellphones can play full-audio ringtones, you can “red box” payphones a bit more casually without having to carry extra equipment! (… If you can find a payphone that this is still compatible with, of course. 😅)
In rural areas, which have a lot of older payphones but less cellphone towers or coverage, this could come-in-handy.
Anyway I put together this nice little “redbox.mp3” sound-file, which has two “25¢ deposit” tones (spaced evenly), and it actually sounds like a modest, polite ringtone! Great for message notifications.
“But, why would you need a payphone if you have a cellphone,” you may ask? — Well, you never know, haha. Either way… obviously you want a “red box” ringtone! After all, it's the phone company's fault if the coin deposit tones happen to match the frequencies of the blips on your ringtone! 🤣
Toss this MP3 tone onto yo' phone. 😉
