Error while interfacing with mega #53

Im trying to use GSM 900A module ( not shield) with arduino mega. I have changed RX and TX pins accordingly to 10 and 11 but I'm always getting same error message on COM port "init error". When i used with normal AT commands it worked very well but now with library its not working.
