The new version of the "바뀐연락처찾기FON" is now available for Android!

In order to use the new version, please install it first.

This version includes some changes, such as the addition of the new function of "Find Old Number: FON". You can now search for the old number, which will allow you to find the contact that you had before.

The contact information of the users that are using the app is saved in the phone. If the number that you are trying to reach is no longer in the phone, you will not be able to send a message to that user.
