Hi, I'm making a program that can send an SMS message to a cell phone using any number that the user chooses. I have been successful sending a message with an SMTP server that says it's from an email address, but I need to make it show up as a number. For example, person A send a text to person B with the number "1-234-567-8910" that says "hi". It's like a spoofing program. Anyway, how would I change the number?
Here's what I'm doing on an SMTP server:
helo www.google.com
mail from:aaa@gmail.com
rcpt to:**********@email.uscc.net
data
Subject:hi
Hello, this is a message
.
quit
