Is there method to send by not using SMS? I tried to send a message. After that, it displays the following toast:


  SMS is unable.


I can't use SMS. Is there a method to send messages by not using SMS?
Google Messenger is an SMS/MMS application. If you are not able to send SMS/MMS for some reason, you need to use a different messaging system and a different application. For example, you can use email, or a proprietary service like WhatsApp. If you need your message to arrive as an SMS, you can use a email-to-SMS gateway, though you need to know the carrier used by the recipient.
