I've got an old Moto V3m that I had flashed to PagePlus but ever since the flash I have only one ringtone, the British Police siren. I can scroll through and select any of the other pre-installed ringtones, but they don't play, just the one.

It has a slot for a micro SD card. Is there a way to download a ringtone--preferably free but I would pay a buck for a normal ring--and somehow install it? I don't want a pop song or anything, just a standard ring.
