To call back home i guess most of u Pakistan or India what u have to do is that:

1. Download a program called mig33 from your mobile web
2. The url to download this software from ur phone is wap.mig33.com
3. For this u should have a java capable phone.
4. Then as u sign up for a account (which is free) u will get some free minute in beginning.
5. when those min finish dont worry...... then u have to invite somebody to join mig33
6. if somebody joins mig33 on your invitation then u will get some more minutes.
7. same thing happens as u keep on inviting more people.

Requirements: Java Enabled Phone
Mobile web Connection from your service provider

I know u will say thankyou...
