Hi, I have a an AG Chrome Ultra. I have two cell c sim cards. When both of them or one of them are in the phone it goes to no service, did a sim swap and the problem persists. I put my dad's cell c sim in and it works 100% but when I put one of my sims in with my dads sim then both sims goes to no service. I switched the sim between sim slots multiple times. Both my sims work in another phone. Can anyone help??
