Unhappy [Q] WIFI issue with Syrian sim

I have Xperia S "OpenSEMC 4.4.2" , and i face known wifi problem in Syria
wifi stops working when i insert Syrian sim card until remove the sim and reboot , tried to change the "wpa_supplicant" with the stock one but didnt work , then tried to change patched "telephony-common.jar" didnt work too .
Is there another solution to try it ??? or how i can edit "wpa_supplicant" ???
