It was definitely a Nokia. You were mad to use anything else back in the day, although I did move to Windows Mobile before the iPhone and then Android were released.
I grew up in the mp3 era, like fuck I was going to pay actual money for my phone to play a short sound clip when I got a call.
Instead I spent money to get a USB to whatever proprietary connector the phone had (that was specific to that phone), found a converter that would do wav -> whatever weird format ringtones needed to be in, figured out where in the filesystem that file needed to be, and then I had my FF7 battle music ring tone.
And these days, despite it being a lot easier, I just haven't bothered setting a custom ringtone. Where did I use to find the time to care about that shit?
Cool kids would compose their own monophonic ringtones with the built–in composer utility.
