You should have a number or website that you can check your prepaid card balance. It also depends on what prepaid card you have. For example, if you have a Prepaid Visa card, you can opt to have your balance sent to your cell phone or e-mail address. If you don't have a prepaid Visa, then I'd suggest checking the back of your card for a phone number or website you could visit to view your balance. Hope this helps!
