  • Would I be able to switch carriers without having to switch phones? I'm with Consumer Cellular and I have an iPhone SE, but I'm thinking of switching carriers so that I can get unlimited data. I don't want to get a new phone because I've had my current one about six months, I really like it, and it works great. I'm not locked into a contract with Consumer Cellular. Would I be able to switch to another carrier without having to purchase a new phone?
