Just wanted to provide a data point, I bought a few of these and registered them with no issues. I tried to register my wife and it kept rejecting her enrollment and I couldn't register anyone else to that card. Called MVD and found out that even though we have lived at this address for over 2 years, since she just changed her name it shows that she hasn't lived here long enough…also the reason she couldn't get a BB, T-Mobile, etc.
So to remedy this, I was able to have them unregister the cards and they turned them in to credit cards. I was able to put a pin and zip code on it. Was able to successfully use them to buy RLs. Obviously not a good way MS, but if you find yourself with a temporary card that you just can't register this is an option. They wanted 9.95 to refund the card or 4.95 to transfer to one of my MVDs.
