kt M모바일 is a lifestyle application developed by kt M mobile Corporation. The app provides various services such as new subscription, additional service application, and real-time usage inquiry. It offers customized subscription services, ranging from self-subscription that can be opened immediately without a consultant to online subscription that is conducted with a consultant.

One of the app's unique features is the same-day delivery service. Even if users do not have a USIM, they can apply for the service and receive it on the same day. Users can also choose a communication fee that suits their style, from a reasonable usage fee to an unlimited usage fee without any contract period. The app has several convenient features such as a real-time usage check widget, chatbot, frequently asked questions, product application/change, and a benefit/event section.

The app requires access to the user's phone number and storage to save login information, widget settings, and temporary files. The app also asks for access to the user's camera to take pictures for ID verification and to the user's location to find nearby sales locations. Refusing access to the required permissions may restrict the app's usage.
