So, there are NO USA number international roaming, free incoming in other parts of the worlds SIMS. I think, there never will be. USA is the only country that doesn't do the CPP thingy, so the math and billing and cross billing would be tough. That is why the callback pricing is so cheap.

I setup the riiing with an 800# in the USA, that costs me 1.00$ a month, so people in the USA just call the 800#, everyone else gets the LIC number, or the 800#, it works for me to pay the .15$, rather than have people not want to call, or god forbid call LIC without a calling plan or something.
