I'm trying to use my provider's free web-text messages to send a concatenated SMS.. I've seen a site that had examples of how to send ringtones and business cards that way.. the messages would start with SSCKL and then a port number. I cant find the site any more though.
I have looked through the smart messaging PDF but it only tells me how to send concatenated messages using at commands and that. and i guess i dont need to convert them to 7 bit encoding because the website takes in ascii characters. Also i tried sending ringtones to my phone before (5210) with the messages starting with SSCKL or something, then a number and a header or something and then a bunch of hex code. the phone did say "ringtone received" and that but it wouldnt play.
