I want to take my daugthers phone over thats still being paid for in installment plan at US Cellular. I can upgrade to an Iphone but she wants to take over the Iphone and I take her s6 but when I asked U S Cellular on the phone They said it cant be switiched unless the phones were paid off.. Is there anyway to switch phones even though both phones are in installment plans??? WE BOTH R ON SEPERATE CONTRACTS AND WANT TO KEEP OUR SAME NUMBERS??Any help would be apprecated
