Pre-paid Internet

I noticed Codetel has a new pre-paid internet service. However they don't explain a lot in their website, other than it is through the use of their Comunicard calling card. Has anyone used this? If so how does it work? I use a similar service when I go to Mexico, through Terra. It is great for those people who are just going to the country to spend a couple of weeks, for whom it doesn't make sense to have a permanent account, but need to use the internet with their laptop. Looking to see if this is a similar service. I always take my laptop with me when I go to the DR as I always have to check e-mail and do some work while in the DR and end-up spending a ton of money on long distance calls as my company's ISP has no local access number in Cotui. Anyways...Would like to hear anything anyone knows about this.

OK...Never mind the part about how to use it. After I wrote this I realized that they DID explain how to use it, etc...Mental freeze...

Still would like to hear about experiences with this, if anyone has any.
