Example 1	To query the present status of ME's network registration using the test com-
	mand:
	AT+COPS=?
	+COPS:	(2,"D2",,"26202"),(3,"E-Plus",,"26203"),(3,"T-

D1",,"26201"),(3,"Interkom",,"26207"),,(0-4),(0,2)

OK

Registered operator is D2. The other operators are present in the network, but not allowed to be used with the current SIM card.

To query the status of the ME's network registration using the read command:

AT+COPS?

+COPS: 0,0,"D2" (command returns mode, format, registered operator)

	OK
Example 2	Attempt to manually select a forbidden operator:
	AT+COPS=1,2,26203
	OK
	If the selected operator was not allowed, the ME is now unregistered. The
	read command will return only the mode, but no operator:
	AT+COPS?
	+COPS: 1
	In this case, the test command returns only that the desired operator is avail-
	able (<stat=1). Nevertheless, the registration is not successful. Please use the
	AT+CREG command (Chapter 4.41) to verify the registration status.
	AT+COPS=?
	+COPS:	(1,"D2",,"26202"),(3,"E-Plus",,"26203"),(3,"T-
	D1",,"26201"),(3,"Interkom",,"26207"),,(0-4),(0,2)
	OK
	AT+CREG?
	+CREG: 0,3		(where 3 = registration denied)
	OK
