You are right - a MUCH CHEAPER alternative to intl. SIMS.

But with Pingo.com, onesuite.com, tel3advange.com, if I call the toll free number by mobile, I'll pay for receive in USA, because it's a call-back number, so it's not so cheap...or there are a possibile to make a direct call?

And I see that pingo, for example, as a montly tax.....

So...what's the best to call from a mobile phone to...the world?
