Caller tune function allows the caller to hear the
tune which is set by the call recipient.
1. If you are the call recipient,
You can modify/remove your caller tune option
on [Me] page > Settings > Function > Caller tune.
2. If you are the caller,
You can let the call recipient modify his/her
caller tune when you feel uncomfortable.
To modify your ringtone:
Enter [Me] page
> Settings
> Notifications
> Calls
> Ringtone.
Tips:
After somebody calls you for the first time,
he/she may hear your new caller tune.
Ensure a stable network and you and your
contacts use the new imo.
