Below are some sites used by me regularly to get free mobile recharge. Check them out,

1.) mCent :

mCent offers free airtime for taking surveys, referring friends and entering into contests. If you ask me the best way to get talk time with mCent is through referring friends as surveys and contests are not always available.
