About this app

[U - Mobile Administration] Introduction to Key Services

※ This app is not the official government app representing Ulsan Metropolitan City Hall.

01. Do you need the other party's information before making a call with group (organization) members?

Check the other party's information in advance when making or receiving calls on your smartphone!

* To provide this feature, we identify the other party's phone number when making or receiving calls.

This information is used solely to determine whether the other party is an organization member and is not stored.

02. Do you need a flexible work environment with enhanced mobility, such as working from home or remote work?

You can use your office phone anytime, anywhere with your smartphone, even while working outside or on business trips.

03. Do you seek a work-life balance where personal information is protected and privacy is respected?

Even when making work calls on your smartphone, they are routed from your office number, allowing you to process work without exposing your personal information.

04. Do you need customized services based on your work status settings?

Call forwarding settings are available that reflect your real-time work status, such as work, meetings, business trips, or vacations.

05. Are you concerned about the investment costs required to introduce the service?

No system investment! No maintenance! You can use the service simply by installing the application.

[App Access Permission Guide]

* Although you can use the app even if you do not agree to all permissions requested by [U - Mobile Administration],

functions such as displaying your phone's contact list and displaying information about the other party's organization members may not work.

- Notifications: Display notifications provided by the server

- Call History: Identify the other party's phone number when making or receiving calls

- Contacts: Provide a list of phone numbers existing in your phone's contacts

- Phone: Identify the other party's phone number when making or receiving calls

- Display over other apps: When making or receiving a call, if the other party is an organization member, display the other party's information on the phone screen while the call is connecting or in progress

To implement these core functions, our app requires the following access permissions:

Detect currently running apps: To identify whether the default phone app is active upon receiving a call, and to accurately display the caller/recipient profile overlay on top of it.

Access to screen content information (limited): May be used in a limited manner to detect call-related information (e.g., call status, outgoing/incoming numbers, etc.) and link it with profile information.
Use your office number anytime, anywhere! It is a mobile phone service that safely protects your personal information and provides business continuity.
