UpCall is a useful application that helps users identify unknown numbers, particularly when receiving calls from Turkcell numbers not saved in their contacts. The app allows users to see the caller's identity while the phone is ringing, providing a convenient way to determine who is calling. Additionally, users can utilize the advanced search tool to query unknown Turkcell numbers and easily reach out to the desired contact. Beyond caller identification, UpCall offers various features such as a do not disturb function, personalized operator names, customizable tones for callers, and the ability to add photos, stickers, and notes to calls.

In addition to identifying unknown callers, UpCall enables users to call numbers not saved in their contacts, expanding the functionality of their phone directory. By querying Turkcell numbers based on names or vice versa, users can efficiently find and contact individuals. The app also allows users to search for a place number by name, view its location on a map, and plan a route. Moreover, users can enhance communication by adding photos, stickers, and notes to calls, providing context to the recipient even before answering the call.

Furthermore, UpCall offers features to enhance user experience and phone management. Users can receive warnings about spam calls, utilize the do not disturb feature to appear unreachable while keeping the phone on, customize the operator name displayed on the screen, and select tones for callers to listen to while the phone is ringing. The app also provides a consolidated view of all calls on a single screen, offering insights into call history and service notifications. While some features are exclusive to Turkcell subscribers due to network restrictions, the application is available for use by all operator subscribers in Turkey, offering a comprehensive solution for call management and identification.
