SIM application toolkit access problem for WAVECOM CDMA module!!!

[mahmudur.rahman]

hi everyone,
i have a WAVECOM CDMA module. i am trying to access the Sim Application toolkit.
i did manege to get the main menu using AT+SMGI=0\r command after getting the +STIN = 0 from the module. then i get 4 items in the menu the are given bellow...
+STGI: “e top-up”
+STGI: 1,4,”Prepaid”,0
+STGI: 2,4,”Billpay”,0
+STGI: 3,4,”OptionR”,0
+STGI: 4,4,”My Wallet”,0

now i should get something like +STIN = 6 (according to wavecom at command example) when i use AT+STGR = 0,1,1\r

but pblm is i am getting just an OK.

so my question is,
am i doing something wrong?
is there any other way to access sim application tool kit for CDMA?

by the way, the sim is ok coz i can access it from my cell.
