About this app

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, NR5G. 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 needs two prequisite conditions before you are using this tool. first only support Qualcomm chipset models. Secondly NSG need cell phone a super user access within your android phone and you have to root the device before NSG is running.

Starting with version 3.8.0, NSG support Hisilicon chipset (5G only). Hisilicon chipset model does not need root permission, but requires a specific firmware version. Please contact the developer for specific 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.

Band Locking enables you to allow your phone to only search for service on the bands that you specify. This is important if you are trying to identify specific coverage in specific locations, or do other testing with your phone. Additionally, if you find that one band is severely congested, you can force your phone to stay on a different particular band.Network Signal Guru is a new app that gives TONS of information on the cellular networks that you are connected to.

Thanks and Best Regards,

NSG Team

First of all, the app works great. However, the cost just to stop the pages from scrolling and the ad to go away is completely well out of the price range for most of us enthusiasts! I understand that you're targeting this to more professionals but there are a lot of enthusiasts like us who use it not for the professional features but for simple band locking and cell identifying. I'm someone who owns several phones to identify and map cells as a hobby, not profit, so $50/month is way too much. Please, consider a much cheaper version for us so that we can continue doing what we do!

This is a really great app for network testing and surveying. The price does reflect the fact it replaces dedicated test equipment, and you do need a rooted phone with a supported modem - it's not so much a general purpose app as it is a specific app for network testers. If this is the app you need, you'll find it very helpful. The customer service is also excellent, the developers are happy to assist with any issues.

A very detailed, easy to use and user friendly app. The free version does contain ads however they are minimal and non intrusive. I am using the licenced version however as it provides far great granularity and functionality. If you are interested in RAN then this app is a must, it is also great for troubleshooting band experimenting.
