ATD*99# not working

Hi,
I’m using the Hologram SIM in Italy on a CINTERION BGS2-T modem.
My device uses the standard gprs ATD*99# command to setup the connection, but it seems that the sim can’t handle the connection.
My code is:

AT+CGDCONT=1,“hologram”,“”,0,0
$OK
ATD*99#
$CONNECT

$NO CARRIER

I’ve got it working with the internal Internet AT commands, so the sim and the modem can talk and work together.
