A:AnswerYes, I'm planning on switching to mint mobile and when I put in their introductory sim card it ran just fine. And I'd switch to my cricket sim card to not miss any calls or texts to my old number and it worked fine too. As someone who was using 2 services at the same time it wasn't a problem at all
