Comments on GSM Signal Monitor & SIM Info for Android

★★★★★ PavewayBilly93 BaDAzz · Dec 27, 2024

This app is good any area u go in makes my phone faster it will let u know on the map how far how close cell towers are keep up Greatvwirk my cell bars have not dropped lower than 3 bars always 3 bars or higher thanks whoever made this app they knew what they are doing

★★★★★ M C · Nov 7, 2024

I have had no problems. The GSM Signal Monitor is very accurate. I have checked it against a professional signal meter. Use it to indicate the best area for cell service. Often 2 g signal is stronger, especially around obstructions and rural areas. The 2g is still the staple connection around the world. Great app so far. Thanks. Ps. Bad signal and dropped calls.go back to 2 g except for data it is much stronger for call quality than 4 g in some areas. Update: Great info it provides still no

★★★★★ Merry Slink · Oct 26, 2024

I live in an area with spotty coverage, it works, it notifies me when my phone has no coverage, also when my signal is low

★★★★☆ Osita Ezeike · Mar 1, 2026

It gives update on disable network and available network with voice updates. Like GSM signal lost with voice that cool. God bless them🤗

★☆☆☆☆ Fahiyan Brahma · Jun 11, 2025

What is this it doesn't show the network tower in the tower controller. TOP

★★☆☆☆ Rob I · Feb 10, 2026

Information is very basic. I don't understand why you would want notifications of signal categories. I think is serves no purpose since phones will automatically switch sims when the signal is too weak.

Billions of "legitimate" ad vendors, no "reject all" ciao, ciao uninstalled

★☆☆☆☆ Xalagij Kepot · Sep 22, 2024

Does not run if you deselect so called "legitimate interest" cookies. Pretends that "adds are needed" to run (or pay), what would be acceptable. But that's not the whole thing: you mandatory have to allow personalized adds with all cookie espionage stuff. Sorry, no way – uninstalled at first (not complete) run.
