I searched a lot of things about the Flash sms class 0, and I'm really interested in the AT+command to send flash sms to any number. But I read that this command can be used only on specefic devices, like some versions of Nokia. Also, some people did this on a basic Terminal on OS X with a 3G+ key.
Please can someone explain me which phone do I need to execute the AT commands, or what 3G+ key do I need ? I didn't find a real tutorial on how to do that... For example if I buy an old Nokia phone, is it OK for sending the AT commands ?
Thank you.
