thanks. but this is a different question.
in this case, i do not have access to a gprs radio/modem. all i have is the computer and ethernet connection to the internet. i need to develop the messaging application for that.
- what protocols do i use to send SMS to a gprs radio?
- what information do i need to provide to the wireless service provider?
- what information do i get back from the wireless service provider to confirm receipt of the message?
No, it isn’t!
