I am creating a schematic for GSM module with SIM900A in eagle, and found that it doesn't have the VBAT and GND pins.But if I try with the ERC it will show the errror "No SUPPLY for implicit POWER pin IC5VBAT@1 VBAT" . Can anyone provide me the solution and also I want to know whether if this pins are invisible, how to make them visible ?

I got the option for making visible.

Use the Invoke command to do this. Click the Invoke button and then select the part you are interested in. You will see the invisible pin list and parts
