Do you know ? Network Signal Info / Pro are UNIQUE
This type of software is ONLY available on Android smartphones - neither iOS nor Window Phones.
Two widgets, one for mobile- and one for WiFi-signalstrength.
(If you can't find widgets, please copy the app to phone memory)
I have put special value on the visualization of the WiFi and mobile signal strength. They are normally only divided in weakly, good and excellent. Graphically in the form of mostly "only" three to five bars on the Mobile Radio and three to five "waves" by a WiFi connection.
In my app I differentiate the signal strength in total 14 bars. This will give you a quick visualized and detailed information about how good the signal strength is really.
In addition to the much more sophisticated graphical representation of the signal strength you will see some more interesting information.
In "Mobile Signal":
Network operators, Sim operator, phone type, network type, network strength in dbm and ASU, data state, data activity, country code of the mobile phone, device ID, IP address, roaming state.
In "WiFi signal":
WiFi-Name (SSID), BSSID, MAC address, maximum WiFi speed, IP address, external IP address, net capability, net channel, subnet mask, Gateway IP address, DHCP server address, DNS1 and DNS2 address.
If you like the app, please give me a positive rating in the market.
The Pro version (compared to the free version) has no ads, a NEW cell tower database with more than 22 million entries, a NEW MOBILE SIGNAL TRACKER function that generates a KML file for use with Google Earth, more widgets, a MOBILE SIGNAL LOST SERVICE and much more.
*** This application is not longer maintained or supported *** Does not work on Verizon *** 3G & CDMA Support is limited by Android, not by the application *** CDMA requires Eclair ***
Works best with 2G GSM. 3G/CDMA support is very limited.
Please understand what this tool does and does not do before you rate it. If you are not interested in the esoteric details of how the cellular network works, please do not download this app, it will frustrate you and be a waste of your time. Please check website for details.
I have reports that Verizon now blocks locations. Other providers may do same. Bummer. If your provider blocks, please be considerate and don't downrate the app. Not my fault.
Yes it is a battery hog - it needs to be.
No longer supported - latest versions of Android and 3G/4G networks may not be compatible. Please look at OpenCellID instead.
It should be helpful for all the people who mount sector antennas (f.e. GSM sector antennas).
All settings are hidden in menu. For further info read help.
If there is any bug, please send me e-mail.
App is design for ICS, on older devices it can look different than on the images...

SMS Permission required to count the number of SMS sent to track your usage, SMS are never read (use a packet sniffer to check!)
Phone settings permission allows network reset on certain Android versions
Based on our community-generated data we are able to help keep you better connected by giving you a practical solution to the problems of slow mobile internet and dropped calls. Simply follow our signal compass to walk towards better phone signal or see our in-app coverage maps to work out which carrier is best for where you are, useful if you're thinking about changing. Our wifi maps help you find local public-access wireless networks (WAPs).
We use Google Maps in our apps, email us if you cannot access Google Maps, email us to request another map technology.
The Stats tab helps you to keep track of your usage, so there’s no danger of you going over your plan limit on data, voice or text. (NB – this is why the app needs permission to access contacts and SMS, these are the permissions needed to count calls and texts, messages are never accessed or read!).
Maps not updated in real-time. Don’t worry though, we log the information you share with us to improve our coverage maps and signal information. We’re working hard to make sure the data you contribute to the project is available to everyone as quickly as possible.
- Not all towers and wireless routers are in our database - we’re working on it!
- Verizon & Sprint (CDMA) users will see only one connected tower at a time
- Moving in the direction of your cell tower (the signal compass) will not always improve reception due to interference effects/local geography.
- For GSM, cell tower are identified via cell id and location area code (CID and LAC)
- For CDMA cell towers are identified via Network ID, Base sub-station ID and system ID (NID, BSSID and SID).

Charts show the changes of strength level and speed of mobile connection. Log and Statistics display the data about cells which were used by a mobile device. After importing of CLF file containing cell locations data can be displayed.
If you are using dual SIM device the app will work only with the SIM inserted in the first slot.
The application doesn't show neighboring cells data on Samsung devices due to firmware limitations.
Cell Map plots the location and strength of all the cell transmitters that your phone is connected to. Just move closer to one for a better signal!
Cell Map can even locate transmitters that are too weak to make a call from, ideal for areas with poor signals.
3G and 4G connections typically only give information about one mobile mast, but switching your device to 2G will potentially allow you to view more cell sites and is recommended

Not all device, firmware and network combinations are supported, if you have problems please get in touch.
LTE Discovery is a powerful signal discovery and analysis tool that allows users to observe a wide range of useful network and signal information while aiding you in staying connected to the best connection possible.
Use this app to identify and record technical LTE/4G information such as GCI, PCI, TAC, Market/Cell ID's. For supported networks, the LTE Band will also be included (Verizon, Sprint, AT&T, T-Mobile, China Telecom).
If you are in an area where LTE is actively being deployed or that has significant gaps in coverage, the app automates the process of cycling your mobile connection to help you connect to the best signal possible. When left running, this app will help you discover LTE in your market without ever looking at your phone! Your phone will find and reconnect to LTE faster, generate a log of the signal, and (optionally) alert you when a signal is found.
As it works in the background it can log each site and connection it finds. This information is then summarized to help you determine how many towers you have connected to. Logs include time, location, PCI, TAC, GCI, and Band. Sprint users have access to the Visual 1x Logger which displays tower, sector, 1900/800mhz signal information via towers pins on an embedded Google Map.
Users that can access their phone's EARFCN DL and UL channels can plug them into the EARFCN card to calculate the precise operating frequency and band. If your LTE network is one of the ones supported ones, the application will generate the information automatically.
-Identifies bands for Verizon, AT&T, Sprint, and T-Mobile
-Advanced signal stats
-Automated visual logger (Sprint + Pro only)
-LTE log queries with unique band and site information (Pro)
-Live band identifier and stats in the notification bar
-EARFCN band calculator (range and precise UL and DL frequencies) (Pro)
-Automated search algorithms for LTE
-Data connection reset without requiring root
-Alert notification for LTE bands and GCIs (connected and disconnected)
-Wide range of settings to customize your experience (Pro)
The free version is full-featured and useful for many cases. However, please consider supporting us by purchasing the in-app pro upgrade for a mere $1.99. This is less than a cup of coffee at Starbucks and helps us keep the lights on.
Please note we do not natively support band identification for every carrier however, users can help us interpret the network information in their area to add band support for their carrier. If you are interested please send us an email.
If you work in the industry, feel free to email us if you have any knowledge that may be able to help us. (Our email can be found in-app)
History: This app was originally developed for Sprint users searching for 4G LTE signals in emerging Sprint markets. Though, users with other carriers including both GSM and CDMA carriers can also greatly benefit from using this app. The only features not available for non-Sprint users is tower location and 800Mhz SMR detection. There are no other limitations for other carriers.
From user reports, Verizon sometimes provides tower location, but they are typically inaccurate.
By resetting mobile connection, you can fix many common network related issues like: continuous low signal, data disconnection, poor call quality, signal instability, and more. You could also fix these issues by restart/reboot your phone, or you could just let LTE Discovery reset your radios in a few seconds.
RATINGS: If you like this app, please support us by rating it 5 stars and helping with a +1, or let us know how we can improve the app.
SUPPORT: If you notice any problems, please use the "Send debug email" option in-app and provide us as much information as possible about the problem.
The data can be written to the SD card (CSV, KML - GoogleEarth format) and it can also be uploaded to http://signalcoverage-locked.rhcloud.com
Keep in mind that - depending on your settings - tracking might consume a lot of cell phone power.
If you want to extend the app, feel free to contribute or fork the project from
・May be no neighboring cells on LG, Samsung, Acer, SE, Huawei and in GSM 3G, CDMA mode (limited not by my app, contact manufactures)
・Samsung devices may have bug with signal strength (I can't do anything, contact manufacturer)
・No TA, Rx, Tx, frequency bands, there is no way to set channels (it is an Android limitation)

Special thanks to S4GRU for their tremendous support of SignalCheck from the beginning! Visit http://www.S4GRU.com for up-to-the-minute information and discussions about Sprint's Network Vision strategy, as well as talk about devices and other cellular networks. There is a SignalCheck discussion thread too.. check it out.
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 information is available for some providers, and frequencies are displayed on some HTC devices.
SignalCheck also displays the current connection type along with the carrier name for each connection, even while roaming. Sprint users are instantly able to see if they are on the new 800 or 2500 MHz (Spark) networks, part of Network Vision!
SignalCheck is a great compliment to the Sensorly app, allowing you to check your signal strengths and map them out so other users can see the data as well.
Users can upgrade to SignalCheck Pro (available here) for less than what a cup of coffee costs these days. The Pro version includes lifetime upgrades, and the following enhancements:
* Pro: Faster access to program updates. Lite users will receive all appropriate updates, but the Pro version is always released first, typically about a week in advance.
* Pro: A configurable widget can be placed on any home screen, showing current connection type and realtime signal strengths. Each field is color-coded so signal information can be checked with a quick glance.
* Pro: The ability to notify the user with an audio and/or vibrating alert when a 4G LTE or Sprint 1X 800MHz SMR signal is discovered. This is handy for users traveling in new cities, or if your carrier's network is being upgraded -- know immediately when you have a high-speed connection! Alerts are customizable, and can be disabled by the user if desired. These features are very useful for Sprint users during their nationwide Network Vision rollout.
* Pro: 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. An additional icon can be enabled to always show 1X CDMA signal for comparison, if the user chooses to do so. These notifications can be configured to automatically run your device boots if you choose to do so.
* Pro: The ability to automatically keep the screen on while SignalCheck is in the foreground.
* Pro: An option to quickly reset your data connections from within the app.
* Pro: The ability to display your base station location (1X tower or sector location) street address, and instantly show it in your favorite mapping app by tapping on it.
* Pro: Easy access to advanced Android screens such as Battery Info, Field Trial, Mobile Networks, and Wi-Fi info. These screens are already available on most Android devices, but are only accessible by special dialer codes.
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.
