unable to read SMS received on my phone

[MAGest 0]

hello, I created a delphi application that controls my phone, I used the TZylGSM component, the application works very well with a GSM modem USB (DLink) and even with a Nokia phone (c1,c2,c3) except that receiving SMS with the Nokia phone does not work.
The SMS is received in the phone but the application does not detect it.
