How can I get my Android device country code without using GPS

Question

An Android mobile actually does know quite well where it is - but is there a way of retrieving the country by something  like a country code or country name  There isn t any need to know the exact GPS position - the country code or name is sufficient  and I am using this code   String locale   context getResources   getConfiguration   locale getCountry Locale getDefault      System out println  quot country    quot  locale    It gives me the code  quot US quot   but my device kept in India  Is there a way to find the device s current country code without using GPS or a network provider  Because I am using a tablet

The checked answer has deprecated code  You need to implement this   String locale  if  Build VERSION SDK INT  gt   Build VERSION CODES N        locale   context getResources   getConfiguration   getLocales   get 0  getCountry      else       locale   context getResources   getConfiguration   locale getCountry

For some devices  if the default language is set different  an Indian can set English  US   then context getResources   getConfiguration   locale getDisplayCountry     will give the wrong value  So this method is not reliable  Also  getNetworkCountryIso   method of TelephonyManager will not work on devices which don t have SIM card  Wi-Fi tablets   If a device doesn t have a SIM card then we can use the time zone to get the country  For countries like India  this method will work  Sample code used to check the country is India or not  Use the below values in your constants file  Constants INDIA TIME ZONE ID   quot asia calcutta quot   Constants NETWORK INDIA CODE   quot in quot   And in your activity  add the following code  private void checkCountry          TelephonyManager telMgr    TelephonyManager  getSystemService Context TELEPHONY SERVICE       if  telMgr    null          return       int simState   telMgr getSimState         switch  simState                If a SIM card is not available then the            country is found using the timezone ID         case TelephonyManager SIM STATE ABSENT              TimeZone tz   TimeZone getDefault                String timeZoneId   tz getID                if  timeZoneId equalsIgnoreCase Constants INDIA TIME ZONE ID                       Do something                           else                     Do something                           break              If a SIM card is available then the telephony            manager network country information is used         case TelephonyManager SIM STATE READY               if  telMgr    null                    String countryCodeValue   tm getNetworkCountryIso                        Check if the network country code is  quot in quot                  if  countryCodeValue equalsIgnoreCase Constants NETWORK INDIA CODE                           Do something                                   else                         Do something                                             break

There isn t any need to call any API  You can get the country code from your device where it is located  Just use this function   fun getUserCountry context  Context   String        try           val tm   context getSystemService Context TELEPHONY SERVICE  as TelephonyManager         val simCountry   tm simCountryIso         if  simCountry    null  amp  amp  simCountry length    2       SIM country code is available             return simCountry toLowerCase Locale US                     else if  tm phoneType    TelephonyManager PHONE TYPE CDMA       Device is not 3G  would be unreliable              val networkCountry   tm networkCountryIso             if  networkCountry    null  amp  amp  networkCountry length    2       network country code is available                 return networkCountry toLowerCase Locale US                                    catch  e  Exception              return null

If you wish to get the country code without asking for any permission  you can choose a tricky way  The method simply uses an API to get the country code  and there aren t any third-party libraries to depend on  We can create one for us  Here I have used Google Cloud Functions to write an API and it is so effortless  Step 1  Create a Google Cloud Account  and set up billing  the free tier is enough  Step 2  Create a cloud function to get the geo location Copy this basic function to the code editor of index js  const cors   require  cors    function  geolocation req  res      const data         country code  req headers  quot x-appengine-country quot        region  req headers  quot x-appengine-region quot        city  req headers  quot x-appengine-city quot        cityLatLong  req headers  quot x-appengine-citylatlong quot        userIP  req headers  quot x-appengine-user-ip quot          res json data      exports geolocation    req  res    gt      const corsHandler   cors   origin  true       return corsHandler req  res  function         return  geolocation req  res             Also we need to copy the package json definition       quot name quot    quot gfc-geolocation quot      quot version quot    quot 0 0 1 quot      quot dependencies quot          quot cors quot    quot  2 8 4 quot         Step 3  finish  and get the URL similar to   quot https   us-central1-geolocation-mods-sdde cloudfunctions net geolocation quot  Step 4  parse the JSON response and get the country code The response will look like        quot country quot    quot IN quot       quot region quot    quot kl quot       quot city quot    quot kochi quot       quot cityLatLong quot    quot 9 9312 76 2673 quot       quot userIP quot    quot xx xx xx xx quot     Thanks and credits go to the Medium article  Free IP-based Geolocation with Google Cloud Functions

Use the link http   ip-api com json  This will provide all the information as JSON  From this JSON content you can get the country easily  This site works using your current IP address  It automatically detects the IP address and sendback details  Documentation This is what I got     quot as quot    quot AS55410 C48 Okhla Industrial Estate  New Delhi-110020 quot    quot city quot    quot Kochi quot    quot country quot    quot India quot    quot countryCode quot    quot IN quot    quot isp quot    quot Vodafone India quot    quot lat quot   9 9667   quot lon quot   76 2333   quot org quot    quot Vodafone India quot    quot query quot    quot 123 63 81 162 quot    quot region quot    quot KL quot    quot regionName quot    quot Kerala quot    quot status quot    quot success quot    quot timezone quot    quot Asia Kolkata quot    quot zip quot    quot  quot     N B  - As this is a third-party API  do not use it as the primary solution  And also I am not sure whether it s free or not

You shouldn t be passing anything in to getCountry    Remove Locale getDefault    String locale   context getResources   getConfiguration   locale getCountry

You can simply use this code  TelephonyManager tm    TelephonyManager this getSystemService Context TELEPHONY SERVICE   String countryCodeValue   tm getNetworkCountryIso     This will return  US  if your current connected network is in the United States  This works without a SIM card even
