***This app require ROOT permission and base on QUALCOMM chipset***

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(FDD & TDD). 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. 

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

    Lock lte band stop working after 26 march update,showing forcing and control features error now. Actually nothing is working in app after latest update. Might be devolper removed support for my device.

  14. Carlo-avatar

    The best network monitoring app. I used NetMonster but often had incorrect CA information with a Sony XZP G8141. NSG allows me to lock LTE bands and for example I found an incorrect configuration of a bts near my house (it can do B3+B1 or only B20 but XZP can do B3+B1+B20). Also, I found that my other operator in the UE capability of XZP doesn't have 256-QAM. Highly recommended app!

  15. Brian Gaming-avatar

    Simply awesome! However, can you please make a lite version with focus on locking bands plus Dual sim support? And remove all those intimidating labels and numbers. And make it a paid app that is just cheaper and affordable. PLEASE!🙏🙏🙏

  17. Swapnil K.-avatar

    Band locking not working on my Poco f1(SD845) its useless app. I am using stock miui11 with stock kernel. If Band locking is not then its a useless app. This app used to work well with my old phone redmi note 4(SD625). Edit: Band locking is working again when i place my sim card in slot 1 but it was not working in slot 2. But now I'm very happy its working 😊. Thanks Developers for this useful app

  18. Rajdeep Dutta-avatar

    just found out an issue in my Redmi Note 7 pro...when the sim is on 2nd slot this app doesn't work ( band changes automatically even if a particular band is locked)...But in 1st slot it genuinely locks the band...Please fix this if possible...I want to use sim card and memory card together...

    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!

    I am using NSG to check how the networks are built, CA, TM, MIMO - and for this it is an 100% must-have, the amount of information it squeezes out of the cellphone network guts is amazing!

  53. Nick Olsen-avatar

    The absolute best application out there for viewing real data. As long as you have root, this app will show you carrier aggregation status. Real time SINR and other quality status. All the way down to the SIP messages exchanged as part of VoLTE. There is no other application out there that will provide you with more accurate real time data.

  54. Rishavh shukla-avatar

    used to work great on Android 7. after 9.0 update it does not lock bands anymore. im on rooted version. edit: It turned out to be a problem with my operator there was too much signal disturbance in my area which kept switching my bands from band-03/1800 to band 40. The problem has been fixed and i ran the app on 9.0 and it works as intended.

  55. A Google user-avatar

    Greatest cell diagnostic app ever created! This app allows one to view full information from cellphone's modem. It also allows the important feature of locking bands so phone can be forced to less busy signals or signals that travel further. NSG is an app designed for the professional and power user, there are a handful of features only a cell engineer will find useful or understand the meaning of.

    I love the app, it has worked for exactly what I need. HOWEVER, since I may need to use it for additional phones, I need to know which devices LTE band locking works for. For example, Samsung Galaxy S7 SM-930V ROOTED on a Snapdragon 820 with an ENG Oreo 8.0 with a does NOT allow LTE band locking. However, the Moto Z Play ROOTED on a Snapdragon 625 with an ENG (I believe) Oreo 8.0 does allow LTE band locking. Do you have a compiled lists for which devices LTE bands work for, or is it a Snapdragon model issue?

  59. Troy Baird-avatar

    Literally one of a kind, Dont know of a single product out there like it that doesn't require it's own kernel or a completely dated version of android! or requires physical attachment to a PC. The best thing is, Even without a rooted device, the replay works on qualcom log files.. This makes it so adaptable! Can't wait to see what else the NSG team bring out!

  60. aadrsh bajpai-avatar

    band locking lte working great, but sometimes it disables(and turning off ofcourse) my mobile data and i cant even re-enable it, so i dont have access to internet at all and i have to reboot the phone before i can use it. after reboot it works normal and band locking still applied, but is there any other workaround other than rebooting? please fix this in the future, im using Mi A2 Lite

    Used to work earlier but now shows *no forcing features available* though in very earlier updates it used to work and help me lock lte band on my coolpad 3600I A question is it because of my sd card in hybrid sim slot?? Add a support please 🙏🙏🙏 and i had restarted the phone.... 😃

    Too many ads. Ad constantly pops up blocking important information. In-app purchase prices are insulting.

    I am using this app on my OnePlus 6 and was working great. But lately I've had my phone formatted. Soon after than whenever I'm using this app I facing “Forcing and Control Feature” error. (I'm on magisk 18.1 with Android Pie running on my device). Thanks.

  66. Vinoth-avatar

    When I open the app, the app automatically keeps changing to different tabs within the app without me doing anything. Even if I select a particular tab to view the info in it, the app switches to another tab by itself. Frustration to read any info. Band lock does work though, but sometimes requires a reboot.

  67. Chris Gillmore-avatar

    Fantastic app indeed! No matter if your using the free version or the full version it provides great detail that's either very useful or fascinating. For me, it's both. Highly recommended app! 5* rating!

  68. Akash Soni-avatar

    The app is very good but there's a major issue in Android 9 pie...Whenever I change network bands I am not able to receive incoming calls.. I need to restart my device to receive incoming calls.. This issue was not there in Android 8.1 oreo hope it fixes soon in next update

    Failed to receive online configuration, same as reported by many. I don't know why network goes empty bars during the configuration process, is this a bug or something... Please correct it, I require this app. I have used stock and several custom roms of Redmi 4A, however, issue is the same...

  70. Darien-avatar

    Impressive app but $50 month is out of reach for majority of users. Would be nice if they had something other than ultimate edition. I only want locking support, wouldn't mind paying a onetime fee or something like $1/month for it.

  71. Te Clau-avatar

    Very good app for locking specific band, one problem: when I lock the phone on specific LTE band the pages whitin the app switch very very fast , can I pause them to move to other page manually? EDIT:this problem happens when I have 2 SIM cards active in the same time!

  72. Simon Smith-avatar

    Updates have made the app no longer functional. Disappointing and old versions cannot be used.

  73. abhinav bedi-avatar

    I blocked 2300mhz. Everything works fine even after changing ROM. But the problem is I can't allow 2300mhz. App just freezes when I try to and there is no change in frequency

  76. Vikash Kumar-avatar

    Works but when I force to LTE band 3 my phone(poco f1) keeps jumping from band 3 to band 40 back and forth for few minutes then locks on to band 3. This was not the case in my older phone (Mi4i).

  77. A Google user-avatar

    Can't scroll the message list. Can't pause logging. Can't see the content of the messages. Can't use QXDM or any other Telecom tools when this app is running.

  78. Theo V-avatar

    Useless for my needs as users can no longer force lock network bands, till this issue is fixed this app main reason for installation on Android device is useless and if I could give it zero I would. Note:does not work for Axon7, LG G3, LG G4 and Pixel 3aXL all these devices are Qualcomm SoC based.

    This app has helped me save thousands of rupees i would be spending on wifi. Thanks a lot.

  93. Shubham Sharma-avatar

    Did you guys remove the LTE band lockng on free version? I only used to lock LTE band with this so buying the full version doesn't make any sense. And if this thing is because of my settings or something then please respond. I don't want to spoil your ratings because of that.
