Know your friend's balance - docomo hack

This trick is for all those curious people out there who wish to know their friend's balance for whatever reason.

Both you and your friend must have a docomo card for this trick to work.

So pick up your phone and dial 09045012345, select preferred language by pressing 1 Or 2, now select 1 and then type your friend's 10 digit docomo number and finally press one to know his/her balance.

This trick comes handy specially when one wants to cross check excuses like 'I can't call because I'm short of balance' etc. Other than that, it sure, is to know about friend's balance condition. Isn't it ?
