It is $2.00 a month and .6 cents a minute to call anywhere in Europe. What a huge profit for onesim. I have the number on my business card. So anyone can call me if they need to get a hold of me. All I have to do is go online an redirect the number to the sim I am using. Very simple and efficient. There are many companies that do this, and they have toll free numbers in many countries. I am through with International sims. They are to expensive,and the local sims in the EU are cheap now for roaming.

I tend to agree. I have used VoiceStick.com, in the past, to do this from the U.S. to a pre-paid SIM.
Now, I often manage to make use of T-Mobile U.S. ability to make free calls back to U.S. if you have a wifi connection. That, and the ability to get/send email on my BB for 67 cents/day often means I don't need a pre-paid.
As many have discovered, many LD carriers refused to carry calls to high priced numbers like +372 mobile and formerly to United Mobile in Lichtenstein. I wouldn't dare have business contacts or friends spend lots of $ to call me. I always make sure they can get me by using my regular number - which then gets forwarded.
Once Google Voice initiates forwarding to intl. numbers - it will make things easy. GV has all kinds of advanced features. Numbers are free. You can use them to dial overseas, now, just not fwd.
