Thank you for this post. I got to it from http://modmygphone.com/forums/showthread.php?p=105939#post105939 where i said that using google voice to call free was not possible. I have not tried it out yet but when i do i might try to get rid of mins all together and just use data. I know tmobile will not let you do that usually but you can trick them into taking it off for you.
[…] Now the offer is valid for any person who can dial a 1800 number and if you live in the US, then the call is free, however, you can dial 1800 numbers free from Internet phones like Yahoo messenger, gizmo or skype. […]
