We are going to develop an application using SMS in Java. The application requires sending of messages from mobile to server and vice-versa. Can you please specify any of the SMS gateway and also Java SDK which supports the above specified functionality.
I have had success (in the UK) with esendex - www.esendex.com. It costs �25 for 250 sms messages. Also, you can receive them, and you get a personal test phone number where you can text a web console before deployment.
