Where I can find the USSD commands specification?
- by Lorenzo Melato
I need to implement a simple application to send short notify messages on gsm phone display via a GSM modem.
I know that I can use the gsm USSD protocol to send messages instead of sms in order to speed up the delivery.
Where I can find a detailed reference on the available USSD messages?
Where I can find examples or sample applications?
All mobile operators supports the USSD protocol?
