Get free recharge from Mobiwik

Ok so this is the second time I am trying to post this thing, because the first time my browser decided to close itself without warning me. So Happy republic day. I read a very funny tweet- "The only day when Prathibha Patil has to stand up and do something and she has a grumpy face on." One thing I would say is that I am not sure about this trick As I got it from unverified sources and also because our president has an unhappy face. However I always post any free recharge offers anywhere on earth I am under the burden of posting it. On this special occasSion of 26th January,
Mobiwik provides you a free top up of 10rs.
