Find yourself someone in their twenties who is tech savvy.
I’m not being facetious. Several years ago (before I even had iPhone ) I was enamored of the phones ringtone in the CTU offices on the series “24” and desperately wanted it for a ringtone.
One of my housemates at the time did it for me and emailed it to me and then transferred it to my old Samsung C-17 (not exactly a state of the art smartphone)
Evidently no cables or anything necessary. Just plain old tech smarts.
And the irony of it was that whenever I had it enabled on my phone, I would miss calls all the time because it was so subtle. Definitely not loud enough for a ringtone even at max level.
But seriously, teenagers nowadays can do just about anything that needs doing on a phone. Borrow one from your friends if you don’t have one of your own at home :)
