[eng_boody]

By sending "AT+CREG=0" can disable network registration code
By sending "AT+CREG=1" can enable network registration (which is your case)
By sending "AT+CREG=2" can enable network registration code with location information (location area code and cell ID)

Options 2. and 3. will also automatically emit +CREG messages upon modem boot/network change.

you can read more details at sim 900 at commands document.

note: save current AT configuration by executing AT&W
