Sensorly helps you discover who the best carrier is FOR YOU, using on millions of signal strength recordings made by our users throughout the world:
- 'Compare' is available for every mobile carrier in the world (includes Asia & Africa...). If yours is missing, email us.
- 'Map' is available for some countries only, we add new ones once we have enough data for the country.
** DISCLAIMER **
1) Some Samsung phones (including Galaxy S2, Note, N7 tablets) have a bug on Android 2.x : they do not provide signal strength information for 2G/3G (CDMA and GSM) so Sensorly indicates "unavailable". Some Android 4 (Ice Cream Sandwich) official ROMs fix the issue but some don't : your milage may vary. Some alternate ROMs have fixed the bugs, for example XWKK2 and XXLPH
2) 4G support is EXPERIMENTAL as it is not supported as extensively as 2G/3G in Android.
3) As a rule, we do not adversely affect phones (hence we do not intercept calls !) and we do not collect any personal data, phone number, IMEI. We do not even collect the phone's unique identifier (UUID). We do not need these to build aggregate coverage maps ! See the privacy policy on our website for more.Please read at the bottom for why we need each permission
** DISCLAIMER **
With Sensorly, you can
- see the cause of dropped calls
- test your carrier's network speed anywhere you are.
- see carrier's 2G, 3G, 4G and WiFi coverage on beautiful maps with street-level accuracy
- compare carrier's coverage and signal quality for any location in the world using our unique 'compare' feature
- report indoor locations with poor coverage using Foursquare's list of locations
- map your neighborhood easily with our non-intrusive data collection (optional)
- see everything the phone can say about your phone's network connectivity : cell tower identfication or BSSID, signal strength (RSSI), etc. It works for CDMA, GSM, WiFi, Wimax and LTE.
Our information is provided free of charge, we hope you will contribute to the database and map your neighborhood in return (but you don't have to)Our application is 100% configurable : choose the map to show, enable/disable data collection, automate data collection, send only over Wifi, etc... you have total control.
Note : Maps update within the day, email us through the settings screen if you think there's a problem.
Supported carriers : Verizon, Sprint, AT&T (ATT), TMobile, iWireless, Cricket, US Cellular, Cellular South (C-spire), Vodafone, O2, Telstra, Optus, 2degrees, etc...
