Let me say this. The use of international sims is of good use to some people. I have used the two international card system, and both cards I chose at the time were bad choices. One went out of business, and the other did not work as promised. So I went to local sim cards. I have a toll free number that is on my business card that clients can reach me anywhere in the world that I happen to be in. Since I am always there on business never pleasure the locals can call me without the cost of an international call for them. Since I travel to certain countries most of the time I just do a top up before I leave, and it is ready the next time I come to the country. For calls home there is Skype which I use every day. I am not saying that international sim cards are bad, but they are not for everyone. YMMV.
