Smsmanager sending SMS

Question

I’m trying to send a text with the following code:

final SmsManager smsManager = SmsManager.getDefault(); 
    smsManager.sendTextMessage("phone", null, "Message", null, null);

But nothing happens, it executes the code, no error occurs and do not send the SMS.
Thanks in advance !

I was able to send it the following way:

 smsManager.sendMultipartTextMessage(phone, null ,smsManager.divideMessage(textmessage), null, null);
