Comments on Network Signal Guru for Android

★★★★★ Ursuslot · Apr 27, 2026

The best application for professionals and passionate people about mobile networks.

★★★★★ Rohan Yadav · Mar 17, 2026

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

Deserves 5 stars. Enabled an LTE band that was disabled 😂 Faster now it seems. So far. Thank you!

★☆☆☆☆ 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.

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)

★☆☆☆☆ Grey Greyson · Oct 31, 2025

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.

It's not working in Samsung s25 ultra. Cellular pro is working, but this one is not.
