Right now, the script I'm using needs to be told which wireless provider is being used and then just sends an email out (ie to [EMAIL PROTECTED]). I understand there are some disadvantages to this, so I started looking into Kannel in hopes that it would be a free way to send SMS messages without being dependent on the provider. Can this be done with Kannel? Browsing the archives, it seems I still need to connect to an "SMSC" (I only have a vague idea what this is), which will cost money. Is this correct? If so, what is the advantage of using Kannel over using one of the commercial SMS gateway services like clickatell?
Currently my script only works for US wireless vendors who provide an email interface to sending SMS - from the research I've done, most UK vendors don't provide this, would I then need to use a SMS gateway to send messages to UK numbers? Is the US SMS format "standardized" yet? I seem to recall that being one of the reasons SMS was so slow to take off.
If someone could just point me at a basic tutorial covering all this stuff, I'd be very greatful. I've searched google but most of the information I find assumes that you're already familiar with the basics.
Thanks, David
