The card I got was in May 2004. The website you could log into not only showed you minutes remaining but would allow you to configure some options for the card as well. You could setup speed dial, some theft protection service, maybe conference call, a key number so you would not have to dial your pin # each time. Each add on costed maybe 10 units a month or so. It was somewhat useful.
Now if I could only get the damn website again!!!!
