SignalCheck Pro allows users to check the true signal strength of their connections. Unlike the standard Android signal bars, which often only display the voice signal strength, SignalCheck shows you detailed signal information about all of your device’s connections, including 1xRTT CDMA, EV-DO / eHRPD, LTE (4G), HSPA, HSDPA, HSPA+, HSDPA, HSUPA, and other GSM / WCDMA technologies. Data about your current Wi-Fi connection is also displayed, including signal strength, SSID, link speed, and IP address.

Support for 5G networks and dual-SIM devices is coming soon.

Special thanks to S4GRU for their tremendous support of SignalCheck from the beginning! Visit for up-to-the-minute information and discussions about Sprint’s network upgrades, as well as talk about devices and other mobile networks. There is a lengthy SignalCheck forum discussion thread as well.

SignalCheck will display LTE Cell ID information on most devices running Android 4.2 or higher, and some HTC devices on earlier Android versions. SignalCheck was one of the first (if not THE first) Android apps to provide this information to users. LTE band and frequency information are available on compatible Android 7+ devices. LTE band information is also available on older devices connected to major US providers. Root access adds LTE frequency information on older devices.

SignalCheck also displays the current connection type along with the carrier name for each connection, even while roaming.

One of the best features of SignalCheck Pro is the notification icon(s). A user-customizable icon shows your data connection strength in the notification area at the top of the screen, and more details can be seen in the pulldown menu. Your signal strength is always at the top of the screen along with your other icons.. no need to open the app to check your connections. The icons are customizable, showing signal bars, connection type, digital signal strength in dBm, or connection type with signal strength. A secondary icon can be enabled to always display the 1xRTT signal for CDMA users. All of this is customizable from within the app!

SignalCheck Pro can also notify the user with optional audio, visual, and/or vibrating alerts when user-defined events occur, such as connections to particular LTE bands, complete signal loss, or site pattern matching.

“Neighbor” cells are displayed that are in the range of your device, but you are not currently connected to.

Users can save a log of connected sites, and enter a “note” for each site that will be displayed in the app (ie “Springfield High School Tower”). Notes are also displayed on neighbor cells.

SignalCheck Pro also provides direct access to advanced Android screens such as Engineering debug/data screens, Battery Info, Field Trial, Mobile Networks, Wi-Fi info, and more. These screens are already available on most Android devices but are only accessible by special dialer codes.

Other features include the ability to automatically keep the screen on while SignalCheck Pro is in the foreground, display your base station location (CDMA 1X site/sector location) street address, and instantly show it in your favorite mapping app by tapping on it, and a home screen widget that shows current connection type and realtime signal strengths. Each widget field is color-coded so signal information can be checked with a glance.

A bonus feature is the option to quickly reset your data connections from within the app — but your device MUST be “rooted” for this to work on Android 4.2 and up. This feature does not work on non-rooted devices.

We are always looking for feedback, including suggestions and bug reports.. compliments are always welcome too.

This app has also been referred to as Signal Check, Signal Check LTE, LTE Signal Check, LTE Checker, among other things. it’s just SignalCheck folks.
