My iphone is disabled,I want enabled it without using pc

You won't be able to re-enable it without using a Mac or PC to do so. If you don't have one, see if you can ask a friend or relative to borrow their's. Alternately, you can pay a visit to either your local Apple Store or Apple Authorized Service Provider and they should be able to assist you with this matter.
