Description by QTRUN Technologies(from Google Play)
Network Signal Guru (NSG) is a multi-functional Android OS based tool for voice and data service quality troubleshooting, RF optimization and engineering field work. It supports all wireless network technologies worldwide, and covers multiple mobile layers as well as data stack in real-time. NSG provides extensive test functions for voice, data tests to assess and reflect the real end-user experience of QoS within a mobile network.
NSG covers all test functions and latest technologies such as: GSM, GPRS, EDGE, UMTS, HSDPA, HSUPA, CDMA2000, EVDO, LTE, 5G NR. NSG integrates full recording and decoding of protocol layers on the supported technologies(3GPP, Layer2, Layer3 and SIP) and direct decoding of Layer 3 signaling and data protocol packets on cell phones.
NSG Map offers comprehensive and valuable benefits to combine outdoor and indoor measurements, which reduces the complexity of in locations such as subway, malls or airports.
NSG can support wide ranges of devices, such as Qualcomm, MediaTek Dimesnsity, Samsung Exynos and Huawei Kirin. Basically NSG needs root access for Qualcomm and MediaTek devices. for Huawei Kirin, custom ROM is preferred. for Samsung Exynos variants, NSG need a token from Samsung. you can also use Pixel 6 for Exynos testing, root needed. Please visit our web for more information.
What that NSG team is doing right now is to lower the cost of network maintenance, optimization and engineering processes. Currently a lot of test tools provided in the market are very expensive, some of those are much more expensive than a basestation. That’s why NSG Team launch this app. Please help us more users and carriers can get benefits from this APP.

Why there is only 3.3 star . This is the only and the best software for fixing congestion issue of any telecom network provider ....and I have tried cellular pro.but NSG IS BETTER THAN CELLULAR PRO.👍👍👍... DEFINITELY. GUYS I HAVE A SUGGESTION FOR YOU I THINK YOU HAVE TO INTRODUCE ADDS FOR FREE 5G NR CELL LOCKING AND BAND LOCKING FOR LIMITED TIME LIME 3 HOURS THEN IT WILL AUTOMATICALLY Reset AFTER 3 HOURS THEN AGAIN AND AGAIN .🤔 I think it's a better idea

Powerful Mobile network tool. Even enables band selection in root mode.
★★★★★Roiikka Ta (Kikka Constellation)· Apr 27, 2024

Hangs that requesting network configuration never goes anywhere says could not get configurations after so many seconds. Clearly I have an internet connection because I'm posting this review on the same connection that I just failed to get the configurations on just a minute ago.

Actaully locks bands, great feature when you really don't want to miss a call deep in a building - locked to band 12! UPDATE - Just seen the price for the unlocked version, WHOA, that's expensive. Greedy Dev. 2 stars. Also, its made in China and requires internet connection, so there is potential for state-sponsored spying. (1 star now)

It's not working in Samsung s25 ultra. Cellular pro is working, but this one is not.
★☆☆☆☆Sam Masemola· Jun 2, 2025
App only works when root is "off", when root is "on" no info loads and shows 'NA Testing' with blank pages. Maybe it doesn't work with KernelSU. Not going to waste time testing with Magisk. What a waste of time.
