The terms and conditions of use for this card are incredibly troublesome. Nothing new here, but its still worth looking at the disingenuous logic. (To see the terms and conditions better, click on the image.)
1. The card requires that you acknowledge reading the terms and conditions of use. Yet the card states: "Terms and Conditions of use are subject to change without notice." (emphasis added). So what is the point of agreeing to terms and conditions of use, if the company can change them at any time? (While this is not an online terms of service, take a look at District Court in Texas Rejects Online Terms of Service as Illusory and Unenforceable.)
2. Technically this card is supposed to be a convenience feature to prepay for your future use of the phone. One of the conditions is that: "Airtime expires 30 days from the date it is added to the account". So after thirty days your remaining money evaporates! This is a blatant rip-off.
