Call your phone company. Tell them that your device was stolen. They may be able to disable your device. Unless you have set up a remote disable method on your phone already in the past, there is nothing you can do at this point. If you did set it up in the past, then simply utilize it to disable your phone.
In the future, please try to type in a clear, coherent manner (without alternative uppercase and lowercase letters in random places). It will make it much easier for others to read and try to provide help.
