Q:

why i m not receiving message with my twilio number which i bought? 

When receive message from my twilio account. 
i got message with different number like 400012 or 641011 like this
but not my twilio number which i use to send message is not display in my inbox when i receive message
can i do something so that whenever someone receive message from my twilio number the number in inbox showing is also twilio number? 
 var client = new twilio. RestClient(twilio_account_sid, twilio_auth_token);

            client.messages.create({
                body: msg,
                to: to,  // Text this number
                from: twilio_number // From a valid Twilio number
            }, function(err, message) {
                if(err) {
                    console.error(err.message);
                }else{
                    console.log("here send sms ... ... ...");
                }
            });

my code is simple like above

There are some limitations when sending messages to certain countries from a Twilio number.  India is particularly restrictive and will not let you retain your original number.  Users can still send messages to your Twilio number, they will just receive them from a shortened number like the ones you shared. 
You can read up on the restrictions for sending messages to India in this support article and by checking out the SMS guidelines for India. 
The restrictions for the other countries you need to send to will be different.  For example, in Malaysia your long code phone number is preserved.  Check out the restrictions for your countries here: https://www.twilio.com/sms/guidelines
Let me know if that helps at all.
