Aloha,
I have been able to log on, registered my phone number and have the orange keypad on showing on my iphone browser. I have no idea how to make a call. I tried just typing in the phone number but a little window popped up asking me if I wanted to make a call and it made the call through my phone just like usual.

I don't really even understand how this all works so please bear with my ignorance. I want to call another iphone from my iphone without using my plan calling minutes. Is this possible? If so, how do I do this?

I also would love it if the call didn't show up on either phones' recent call list or on the bill.

Thank you for any help that you can give.
