share reliance data card connection among many devices

G'day

I have purchased a reliance netconnect + connection (reliance data card) for my laptop. Now I have an office laptop and "two mobiles with WiFi capability".
How can I share the internet connection among all my devices.
1. Using a cross cable and sharing the net connection between the two laptops is one option.
2. Tried to install connectify. It sent my reliance netconnect + software for a toss. I had to do a system restore to get things back to normal.

any suggestions?

Thanks
