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.

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,

Ratings and reviews

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.

Superb app. It has a ton of features and shows very detailed information about your network. The best part is the forcing control feature of the app which helps you to lock bands. Great app and would recommend it :D

I used this app to enable SA and NSA in Pixel 6pro but this option is not available in Xperia 5 ii. NSG just showing 2G3G and 4G band lock there is no 5G band lock option for Xperia 5ii 5G device.
