Absolute Best Way To Call To/from Europe?

[DRNewcomb]

You'll love Verona, well maybe after 6 weeks it will get a little old.

You summed it up pretty well. You might want to get two phones and use the Italian (e.g. Wind) SIM for WAP and callback triggering. Use the second phone for incoming calls on your UM SIM. You only want incoming calls on that SIM.
