.06/Min to United Mobile from the states!
 

I just went to Norway with my United Mobile sim. I told my wife to use the VOIP account since it was likely going to be the cheapest. The VOIP was charging .275/Min.

She had to make some calls to me on the home phone for which our carrier is United Carrier Networks (UCN). I expected that to be really expensive.

I just got my bill...and to my complete surprise, all calls to my United Mobile number were charged at .06 per minute!

NOW we are talking ;-)

Awesome!
Now if only I could get that VOIP rate as a forward service

You probably could rig something up, but these rates never hold.
