About this app

Ever wanted to call someone, but your phone has no GSM coverage?

Or you are living / working in a low signal area?

'GSM Signal Monitor' monitors the phone (or tablet with SIM card) signal strength and alerts you when you are out of service or in a low signal zone.

No signal / low signal alerts include: voice notifications, vibration, notification on the device screen and playing a ringtone. You can personalize how you get notified in the app settings.

'GSM Signal Monitor' can also notify you when the signal is restored, your mobile data is lost you are in a roaming area.

The app also provides information about device SIM cards such as phone number, voice mail number, SIM Card Serial number (ICCID), Subscriber Id (IMSI), mobile operator info and network type. This SIM card info can be easily shared by tapping on the share button or copied in the device clipboard.

‘GSM Signal Monitor’ logs every signal related event in its notifications log. The notification log keeps information when the GSM signal is lost, restored or low. It also logs information when the mobile data is lost or roaming is active. You can configure what’s logged in settings. The log can be exported in CSV, PDF and HTML formats.

Each logged event contains location and additional details about device and network states such as: network operator, network type, data connection state, roaming state, ram usage, battery temperature, battery state (charging/not charging) and battery level at the time of the event.

You can monitor your signal strength as it changes dynamically from the app main screen or in the notification area.

GSM Signal Monitor can also provide you with comprehensive and up-to-date information about cell towers worldwide, thanks to its 'Cells' feature.

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

I travel & work in remote areas & the ability to know when I'm out of service would be good. But this app is constantly notifying of service drops of even 1-3 seconds. It happens regardless of how I adjust the Settings. I'm right in the middle of a city testing it, so if it's this bad here I can imagine how it's going to be in the field. I also notice it's using high levels of battery & CPU. I wrote the developer & have heard nothing, so I'm uninstalling.

Hi, thank you for contacting us. Sorry for the late response. We will try to reproduce the issue and fix it in some of the next versions. As for the battery you can set the interval for signal check to less frequent time interval in settings. The app will stop automatically when battery is low and autostart when it is sufficiently charged, too.

Great app. I got a new phone & it's dropping my mobile signal. This app allowed me to track the drops. It displays the results clearly and concisely. I was able to use it to contact the company, show them the log and get my phone repaired as a result. Most apps display complex graphs and stats. This is simple and precise. If you're trying to track a network issue, this app is perfect. There are ads but they're not intrusive and they don't interfere with the apps use. Very nice.
