You can try this    public String ConnectionQuality         NetworkInfo info   getInfo context       if  info    null     info isConnected            return  UNKNOWN              if info getType      ConnectivityManager TYPE WIFI            WifiManager wifiManager    WifiManager  context getSystemService Context WIFI SERVICE           int numberOfLevels   5          WifiInfo wifiInfo   wifiManager getConnectionInfo            int level   WifiManager calculateSignalLevel wifiInfo getRssi    numberOfLevels           if level    2                   return  POOR               else if level    3                   return  MODERATE               else if level    4                   return  GOOD               else if level    5                   return  EXCELLENT               else             return  UNKNOWN            else if info getType      ConnectivityManager TYPE MOBILE                int networkClass   getNetworkClass getNetworkType context                if networkClass    1                  return  POOR               else if networkClass    2                   return  GOOD               else if networkClass    3                   return  EXCELLENT               else                 return  UNKNOWN            else             return  UNKNOWN        public NetworkInfo getInfo Context context        return   ConnectivityManager  context getSystemService Context CONNECTIVITY SERVICE   getActiveNetworkInfo       public int getNetworkClass int networkType        try         return getNetworkClassReflect networkType        catch  Exception ignored               switch  networkType          case TelephonyManager NETWORK TYPE GPRS        case 16     TelephonyManager NETWORK TYPE GSM        case TelephonyManager NETWORK TYPE EDGE        case TelephonyManager NETWORK TYPE CDMA        case TelephonyManager NETWORK TYPE 1xRTT        case TelephonyManager NETWORK TYPE IDEN          return 1        case TelephonyManager NETWORK TYPE UMTS        case TelephonyManager NETWORK TYPE EVDO 0        case TelephonyManager NETWORK TYPE EVDO A        case TelephonyManager NETWORK TYPE HSDPA        case TelephonyManager NETWORK TYPE HSUPA        case TelephonyManager NETWORK TYPE HSPA        case TelephonyManager NETWORK TYPE EVDO B        case TelephonyManager NETWORK TYPE EHRPD        case TelephonyManager NETWORK TYPE HSPAP        case 17     TelephonyManager NETWORK TYPE TD SCDMA          return 2        case TelephonyManager NETWORK TYPE LTE        case 18     TelephonyManager NETWORK TYPE IWLAN          return 3        default          return 0           private int getNetworkClassReflect int networkType  throws NoSuchMethodException  InvocationTargetException  IllegalAccessException         Method getNetworkClass   TelephonyManager class getDeclaredMethod  getNetworkClass   int class       if   getNetworkClass isAccessible            getNetworkClass setAccessible true             return  Integer  getNetworkClass invoke null  networkType       public static int getNetworkType Context context        return   TelephonyManager  context getSystemService Context TELEPHONY SERVICE   getNetworkType

If the problem is to find whether the phone s network is connected and fast enough to meet your demands you have to handle all the network types returned by getSubType     It took me an hour or two to research and write this class to do just exactly that  and I thought I would share it with others that might find it useful   Here is a Gist of the class  so you can fork it and edited it   package com emil android util   import android content Context  import android net ConnectivityManager  import android net NetworkInfo  import android telephony TelephonyManager          Check device s network connectivity and speed      author emil http   stackoverflow com users 220710 emil        public class Connectivity                   Get the network info         param context         return             public static NetworkInfo getNetworkInfo Context context           ConnectivityManager cm    ConnectivityManager  context getSystemService Context CONNECTIVITY SERVICE           return cm getActiveNetworkInfo                          Check if there is any connectivity         param context         return             public static boolean isConnected Context context           NetworkInfo info   Connectivity getNetworkInfo context           return  info    null  amp  amp  info isConnected                           Check if there is any connectivity to a Wifi network         param context         return             public static boolean isConnectedWifi Context context           NetworkInfo info   Connectivity getNetworkInfo context           return  info    null  amp  amp  info isConnected    amp  amp  info getType      ConnectivityManager TYPE WIFI                         Check if there is any connectivity to a mobile network         param context         return             public static boolean isConnectedMobile Context context           NetworkInfo info   Connectivity getNetworkInfo context           return  info    null  amp  amp  info isConnected    amp  amp  info getType      ConnectivityManager TYPE MOBILE                         Check if there is fast connectivity         param context         return             public static boolean isConnectedFast Context context           NetworkInfo info   Connectivity getNetworkInfo context           return  info    null  amp  amp  info isConnected    amp  amp  Connectivity isConnectionFast info getType   info getSubtype                            Check if the connection is fast         param type         param subType         return             public static boolean isConnectionFast int type  int subType           if type  ConnectivityManager TYPE WIFI               return true           else if type  ConnectivityManager TYPE MOBILE               switch subType               case TelephonyManager NETWORK TYPE 1xRTT                  return false       50-100 kbps             case TelephonyManager NETWORK TYPE CDMA                  return false       14-64 kbps             case TelephonyManager NETWORK TYPE EDGE                  return false       50-100 kbps             case TelephonyManager NETWORK TYPE EVDO 0                  return true       400-1000 kbps             case TelephonyManager NETWORK TYPE EVDO A                  return true       600-1400 kbps             case TelephonyManager NETWORK TYPE GPRS                  return false       100 kbps             case TelephonyManager NETWORK TYPE HSDPA                  return true       2-14 Mbps             case TelephonyManager NETWORK TYPE HSPA                  return true       700-1700 kbps             case TelephonyManager NETWORK TYPE HSUPA                  return true       1-23 Mbps             case TelephonyManager NETWORK TYPE UMTS                  return true       400-7000 kbps                               Above API level 7  make sure to set android targetSdkVersion                 to appropriate level to use these                             case TelephonyManager NETWORK TYPE EHRPD     API level 11                  return true       1-2 Mbps             case TelephonyManager NETWORK TYPE EVDO B     API level 9                 return true       5 Mbps             case TelephonyManager NETWORK TYPE HSPAP     API level 13                 return true       10-20 Mbps             case TelephonyManager NETWORK TYPE IDEN     API level 8                 return false      25 kbps              case TelephonyManager NETWORK TYPE LTE     API level 11                 return true       10  Mbps                Unknown             case TelephonyManager NETWORK TYPE UNKNOWN              default                  return false                         else              return false                       Also make sure to add this permission to you AndroidManifest xml   lt uses-permission android name  android permission ACCESS NETWORK STATE  gt  lt  uses-permission gt    Sources for network speeds include wikipedia  amp  http   3gstore com page 78 what is evdo mobile broadband html

On top of Emil s awsome answer I d like to add one more method  for checking if you actually have Internet access as you could have data set to off on your phone    public static boolean hasInternetAccess Context c       TelephonyManager tm    TelephonyManager  c getSystemService Context TELEPHONY SERVICE       if isConnected c   amp  amp  tm getDataState      TelephonyManager DATA CONNECTED         return true      else         return false      Note that this is only for checking if theres a cellular data connection and will return false if you have WiFi connected  as the cellular data is off when WiFi is connected

To get a more precise  and user friendly  information about connection type  You can use this code  derived from a  hide method in TelephonyManager java    This method returns a String describing the current connection type   i e  one of    WIFI     2G     3G     4G     5G     -   not connected  or      unknown   Remark  This code requires API 25   but you can easily support older versions by using int instead of const   See comments in code    public static String getNetworkClass Context context        ConnectivityManager cm    ConnectivityManager  context getSystemService Context CONNECTIVITY SERVICE             NetworkInfo info   cm getActiveNetworkInfo        if  info    null     info isConnected            return  -      not connected     if  info getType      ConnectivityManager TYPE WIFI          return  WIFI       if  info getType      ConnectivityManager TYPE MOBILE            int networkType   info getSubtype            switch  networkType                case TelephonyManager NETWORK TYPE GPRS              case TelephonyManager NETWORK TYPE EDGE              case TelephonyManager NETWORK TYPE CDMA              case TelephonyManager NETWORK TYPE 1xRTT              case TelephonyManager NETWORK TYPE IDEN         api lt  8  replace by 11             case TelephonyManager NETWORK TYPE GSM          api lt 25  replace by 16                 return  2G               case TelephonyManager NETWORK TYPE UMTS              case TelephonyManager NETWORK TYPE EVDO 0              case TelephonyManager NETWORK TYPE EVDO A              case TelephonyManager NETWORK TYPE HSDPA              case TelephonyManager NETWORK TYPE HSUPA              case TelephonyManager NETWORK TYPE HSPA              case TelephonyManager NETWORK TYPE EVDO B       api lt  9  replace by 12             case TelephonyManager NETWORK TYPE EHRPD        api lt 11  replace by 14             case TelephonyManager NETWORK TYPE HSPAP        api lt 13  replace by 15             case TelephonyManager NETWORK TYPE TD SCDMA     api lt 25  replace by 17                 return  3G               case TelephonyManager NETWORK TYPE LTE          api lt 11  replace by 13             case TelephonyManager NETWORK TYPE IWLAN        api lt 25  replace by 18             case 19     LTE CA                 return  4G               case TelephonyManager NETWORK TYPE NR           api lt 29  replace by 20                 return  5G               default                  return                           return

Emil s answer above is brilliant   Small addition  We should ideally use TelephonyManager to detect network types  So the above should instead read          Check if there is fast connectivity     param context     return     public static boolean isConnectedFast Context context       ConnectivityManager cm    ConnectivityManager  context getSystemService Context CONNECTIVITY SERVICE       NetworkInfo info   cm getActiveNetworkInfo        TelephonyManager tm    TelephonyManager  context getSystemService Context TELEPHONY SERVICE       return  info    null  amp  amp  info isConnected    amp  amp  Connectivity isConnectionFast info getType    tm getNetworkType
