Which features work on my phone?

You'll have calls, texts, and data on T-Mobile's network as well as international roaming. You won't be able to make calls or text over WiFi, use visual voicemail, or use data hotspots outside the US.

Texting setup

Texting will work with some additional setup, but iMessage works right away.


When you use an iOS device, the Fi app manages voicemail instead of the app that came with your iPhone. To see a list of your voicemails, listen to the audio or read the transcripts, and choose how to respond, use the Fi app.
