GSM Signal Monitor & SIM Info

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.
