iPhone: You call cannot be connected please check your phone setting?
Before i don't have any problem calling someone.
But recently everytime i try to call any numbers may it be domestic or international numbers
my iphone will respone "You call cannot be connected please check your phone setting"
(for example, i try to call my mom cellphone number. Even though her phone is not turn off/busy, my iphone still reply me the same)
i checked my iphone setting already and i think everything is the same. Beside i'm the only one who use my phone. I also did RESET ALL THE SETTING but still the same.
I also visited my network provider just awhile ago. To inquiry maybe it was just my sim card. They check it and it was not my sim card. But the iphone it self. There's NO MAC/IPHONE store near me to fix this.
Please teach me how to fix this.
