Hey hi all, I am currently using BlackBerry Storm 9530, and also this is GSM / CDMA phone. From the last few days I am getting problem with my BlackBerry Storm 9530. At this time I am using the GSM network and while using this network I am not able to dial neither USSD codes / nor GSM codes. I mean to say that when I dial *120# for checking the balance or when I dial #21# to disable call forwarding, it goes like a call and after that I found the reply from there that is "NUMBER DOESN'T EXIST". I am not bale to fix this problem so can anyone help me to solve this issue?
