      • 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.
