스마트메시지 PRO - OK114 콜백문자 서비스

스마트메시지 PRO (Smart Message PRO) is a business customer management CRM for organizing contacts into groups and managing each customer individually. Register phone numbers, customize messages for different situations, and use call logs to select customers or exclude specific numbers from management.

The app supports callback SMS workflows, call and message management, reject-company registration, and customer tracking. Calls lasting less than five seconds can be treated as missed calls for more reliable follow-up. Required permissions may include contacts, photos, call status, and call history; optional photo storage access enables saving shared images. Phone numbers are collected for membership registration and identity verification.
