HaneulHyu Callback SMS is an automatic callback text messaging app designed for work environments that require frequent follow-up messages after calls, such as consultations, sales, reservations, and customer service.
After a call ends, users can send pre-saved callback phrases via SMS, and if necessary, attach images to send along with the SMS. The app focuses on saving time in tasks that require sending the same content frequently, such as repetitive announcements, visit reminders, reservation confirmations, and replies after consultations.

The app operates after the user explicitly configures settings and grants permissions. Permissions for phone status and call logs are used to detect call termination, and SMS permissions are used to send text messages and MMS. The automatic sending function operates based on phrases saved by the user and the selected sending policy.
On devices using dual SIM or eSIM, you can select the sending line. You can configure the settings to block automatic sending if the selected text sending line differs from the line where the actual call is received, allowing you to separate work and personal lines.
The license is verified by the server based on the device's unique ID. First-time users can use a 7-day free trial, and the license is automatically activated according to the selected usage period once Google Play payment is confirmed.
Costs for sending text messages and MMS may apply depending on the mobile carrier's rate plan. Users must verify the sending of promotional information, recipient consent, and sending restrictions in accordance with the actual usage environment and relevant laws.
