I’m not sure how you are getting prepaid Visa and MasterCard gift cards to work on PayPal or even Internet bills. I am getting an error every time try to enter these cards in these websites. My cable provider is with frontier. I am restricted with insurance payments also. My insurance company only accepts ufan prepaid MasterCard giftcards. It is rejecting secure spend visa and vanillas. Not sure why these are being rejected now. These all used to work everywhere.
Another spending idea for low balance cards are donating to charity. They rarely reject prepaid cards, and have very low donation limits.
