Import custom cell database files (.ntm and .clf v3) to enrich network details and view active cell towers on a customizable map powered by OpenStreetMap.
Record radio signal strength and network info during trips (drive tests). Replay them inside the app or export them to .kml/.csv formats to view in external tools like Google Earth.
Built-in speed test utility supporting LibreSpeed, OpenSpeedTest and custom backends.
Tracks real-time network changes, such as cell handoffs and frequency band adjustments; receive system notifications for the events you choose.
Optional background service records network events and trip data even when the app is closed, keeping you updated via an active status notification.
Access hidden Android field testing menus (such as Samsung ServiceMode, MTK Engineer Mode, MIUI BandMode, and Huawei ProjectMenu) directly without dialer codes.
Import speed tests from other apps (might require an account/connection to the respective app's services).
Easily read your SIM's carrier config, IMS info & logs with NetManager's advanced mode through Shizuku.
