I won't be able to answer your question directly but wanted to add ... my friends in NYC who wanted to sign up for this service were told it was a couple months waiting period to get connected. They said forget it. And the question you may want to check further is, is unlimited long distance to ALL parties you call or just parties that are also on MCI. The AT&T Unlimited plan applies only when you call other AT&T customers, therefore IMO making it not that good a deal - especially since I am not going to ask people who their long distance carrier is, keep track who is and who isn't etc. Just a couple things to consider. Also I would love to hear people's experiences with this service. MCI does not offer it where I live and other things I have heard are not great. But when you read it, it sounds great! So please let us know how you make out.
