Saving contacts to SIM (Arduino GSM)

Hello. I have a SIM800 module for arduino and I would like to save numbers on the SIM card. i tried command: AT + CPBW = 1, + 00000000000.145, Name 1. And it didn’t work.
Can someone tell me how to do it better ?
Thanks in advance.

all right I solve the problem. You must use : " AT + CPBW = 1, “+00000000000”.145, “Name 1” "
