DME supports the concept of self-provisioning, meaning that users can request software and OTA configurations on demand. To achieve this, a user needs to know four items of information: An SMS Code, the server's phone number (the phone number of the Kannel or NowSMS modem), a download code, and a PIN code.
Please note that self-provisioning by SMS is not supported on installations where the Kannel SMS gateway is installed on Windows servers. Only Kannel on Linux and NowSMS on Windows are supported.
