Dont do it!
I downloaded this app to make calls over Wi-Fi. I linked it to my Facebook account, purchased a $9.99 calling credit which was deducted from my iTunes account and absolutely nothing worked for me! App crashed or would get stuck on a page saying I still needed to setup my account or purchase time, which I already did both! So frustrating!
