Network Signal Guru APK

Network Signal Guru (NSG) is a versatile tool designed for Android OS that aids in troubleshooting voice and data service quality, optimizing radio frequency, and conducting engineering fieldwork. It is compatible with all wireless network technologies globally and operates across various mobile layers and data stacks in real-time. NSG offers a wide range of testing capabilities for voice and data, allowing users to evaluate and understand the actual end-user experience of Quality of Service (QoS) within mobile networks.

Wide Testing Functionality 

NSG encompasses all essential testing functions and the latest technologies, including GSM, GPRS, EDGE, UMTS, HSDPA, HSUPA, CDMA2000, EVDO, LTE, and 5G NR. It features complete recording and decoding of protocol layers for supported technologies (3GPP, Layer 2, Layer 3, and SIP) and enables direct decoding of Layer 3 signaling and data protocol packets on mobile devices.

The NSG Map provides significant advantages by integrating outdoor and indoor measurements, simplifying data collection in challenging environments like subways, shopping malls, or airports.

Support Wide Array of Devices 

NSG is compatible with a wide array of devices, including Qualcomm, MediaTek Dimensity, Samsung Exynos, and Huawei Kirin. For Qualcomm and MediaTek devices, root access is generally required, while a custom ROM is recommended for Huawei Kirin. Samsung Exynos variants necessitate a token from Samsung, and Pixel 6 can also be used for Exynos testing, with root access needed. For further details, please visit our website.

Currently, the NSG team is focused on reducing the costs associated with network maintenance, optimization, and engineering processes. Many testing tools available in the market are prohibitively expensive, with some costing more than a base station. This is the motivation behind the launch of the NSG app. We encourage more users and carriers to take advantage of this application.

Band Locking 

Band Locking allows you to restrict your phone to search for service only on the designated bands you choose. This feature is crucial for pinpointing specific coverage in certain areas or conducting various tests with your device. Moreover, if you notice that one band is heavily congested, you can direct your phone to remain on a different band. Network Signal Guru is an innovative app that provides a wealth of information about the cellular networks to which you are connected.

Thank you and best wishes,
