Due to the special distribution channel of prepaid phone cards, the phone card issuing companies don't know who use their phone cards. This is different from regular phone service companies such as AT&T, who knows their customers and how to contact them. To minimize legal liabilities, all phone card issuing companies claim that "the rates are subject to change without notice" literally because it will be very hard for them to notify end users.
As a result of this, you will find this notice on our website as well as other online phone card stores. However, eCallChina always tries our best to provide a trustable service for you. If you think the updated rate is not good, you can choose to stop to use the card and return it to us and the remaining balance will be refunded.
