Fi is in beta for iPhones. Bringing your iPhone to Fi requires some extra setup, like changing a few of your Settings. We'll walk you through it step-by-step, and our support team is always available if you need help. iPhones do not support network-switching technology, but you'll still get great coverage. Learn more
Fi works on most phones, but we always recommend checking your phone's compatibility before joining Fi. If your unlocked phone is compatible with T-Mobile's 5G network, you'll have access to 5G on Fi.
