Rezazad, there are China Mobile branches in T1 Terminal. You can find them in domestic departure hall and international departure hall. If your phone supports GSM, then you can buy China Mobile's sim card. If it supports WCDMA, then I am afraid that you need to buy the sim card from the China Unicom branches in the city because I didn't find any unicom branhes in the airport.
