Autofill by Detecting Country Code on App Start

Question

Good Day,
I am making a project in Unity Game Engine (Uses C#), I'm using firebase phone authentication SDK. Everything is working fine, but I need a new function. When user opens app and phone number field shows. I need some sort of API or if any way to get user's country code for example +91 +966 etc
Any help will be appreciated. Thank you ahead of time.

I think there is one solution for that you have to pass a user IP address and then you have to call one API and append user country code.   this is sample code I have written for getting country. public   static   string  GetUserCountryByIp( string  ip)   {   IpInfo ipInfo =  new  IpInfo();   try    {   string  info =  new  WebClient().DownloadString( "http://ipinfo.io/"  + ip);   ipInfo = JsonConvert.DeserializeObject (info);   RegionInfo myRI1 =  new  RegionInfo(ipInfo.Country);   ipInfo.Country = myRI1.EnglishName;   }   catch  (Exception) {   ipInfo.Country =  null ;   }   return  ipInfo.Country;   }
