You cannot use ATD on modem as you do not have a PPP handler in your controller. You have to use TCP commands of modem which internally handles all the response.

You are sending wrong cgreg command format. It should be
At+cgreg?

Use the same format for creg also. I see that you are getting no carrier with ATD. I am thinking your modem is not registered on network.

at+CREG should give response starting with
+CREG: 0,1
or
+CREG: 0,5
