01Restore your default ringtone
iOS 26 can initially select the imported file as your default ringtone. Assign it to the contact, then restore your normal ringtone under Sounds & Haptics.
02Check vibration separately
A silent audio file can still vibrate. To keep the contact completely unobtrusive, also choose None for haptics or vibration when your device offers that option.
03Configure messages separately
The contact ringtone initially applies to calls. For SMS and iMessage, you can also choose a text tone for the contact or mute the conversation separately.
04Make a test call
Call your phone from a second device after setup. Then test a regular contact to confirm that everyone else remains audible.
05Handle messenger calls separately
WhatsApp, Signal and other app calls use their own notification settings. Silent Ringtone works with regular phone calls.
06Keep important contacts audible
Do not use Silent Ringtone for emergency, care or other contacts whose calls you must reliably hear.
