      • Dear Sir,

        First I entered above registration information on related cages in Mobitel Sri Lanka Huawei E5573S-320 Unlocker and hit the Register button. Registration successful message appeared. But flashing was not started. So I closed the program, reopened and tried to enter registration information again. But “registration information is incorrect” message is appearing.
        Please help me. Hardware ID is same. There is no any changes
