If they are not on the new phone you may have to download what you are looking for at a cost.
Or if you have a ringtone on your old phone that you like maybe you can send it by Bluetooth to your new phone.
I have very little knowledge about ring tones so best waiting till you get someone that can guide you in the right direction.
FE did give some information last year about how to download music clips to use as ringtones.
But not sure if he still has that information.
My Granddaughter when she was 10yrs used to put new ringtones on my phone for me.They learn young nowadays.
