[FMC] is a smart callback and customer management solution that provides not only automatic personalized text messaging after a call ends and efficient mass texting, but also caller ID display and blocking of unwanted numbers upon receiving a call.

FMC automatically handles situations where you missed a call while busy, want to send additional information (directions, business cards, website, events, etc.) to a customer after the call has ended, or simply do not want to be interrupted by spam or unnecessary calls.

■ Key Features

1. Caller ID and Spam Blocking

• When a call comes in, caller ID is displayed on the screen, allowing you to identify the caller in advance.

• It detects, displays, and blocks incoming calls from unwanted numbers or numbers suspected of being spam based on a block list (blacklist) registered by the user.

• Blocking and displaying functions operate on the device based on the numbers registered by the user. 2. Automatic Callback Text Sending After Calls

• Automatically sends a pre-configured notification text message to the customer upon the end of a call.

• Customizable text settings are available for various call situations, such as incoming, outgoing, and missed calls.

• Text messages are sent directly from the user's mobile phone.

3. Efficient Bulk Text Messaging

• Conveniently send announcements, promotions, and notices in bulk to a large number of customers at once.

• Supports efficient marketing and customer management through customized bulk texts tailored to customer groups and situations.

4. Flexible Sending Times and Settings

• You can specify or adjust sending times to ensure messages are sent only during desired periods, such as outside business hours, weekends, and holidays.

• Enables sophisticated customer service by setting different message texts for each day of the week and time of day.

5. Smart Sending Restrictions and Exception Management

• Support for registering restricted numbers (blocked numbers): You can exclude numbers you do not wish to receive from, such as personal calls, specific numbers, or internal employees, from the sending recipient list. • Restriction on duplicate sending to the same number: You can set a frequency to prevent repeated sending to the same person within a specific period.

6. Attaching customized promotional content

• You can effectively promote your company introduction, directions, mobile business cards, event pages, and more by attaching images (MMS) and website links (URLs).

■ Highly recommended for these users!

• Those who want to filter out unwanted calls by using caller ID and spam blocking

• Those who want to manage mass text messaging and post-call callbacks with a single app

• Those who want to automatically send notification messages only at specific times, such as after work or on weekends

• Those who need to set exceptions to prevent messages from being sent to specific numbers or personal contacts

• Solo business owners and small merchants for whom customer interaction and marketing are important, such as stores, hospitals, academies, real estate agencies, and freelancers

■ Access Permissions and Usage Guide

• We use Phone (Call Status) permission for callback detection, caller ID, and spam blocking, and SMS permission for the automatic sending of notification messages. • Notification messages are sent via the user's own mobile phone's text messaging function, so they are automatically sent upon the end of a call even when the app is not running in the background.

• Since messages are sent to the user's own number and rate plan, we recommend using a plan with unlimited text messaging.

• Spam blocking operates based on numbers registered by the user and does not guarantee complete blocking of all spam or scam calls.
