Sprint contract ended but it still shows in signal?

I have a sprint iphone and my contract ended but on the signal sign, it still says "sprint". And i still get voicemails from my sprint number and can't log in to imessage and/or facetime since my sprint line is deactivated and my phone is sprint, so its as if they cut off my network line and now i can't log in… I don't know what to do? I can't reset my phone for reasons (even with backup) … What do i do?

Even is a phone is no longer active, it still receives a signal.

iMessage and Facetime are not a carrier functions, has nothing to do with Sprint or any carrier.

What to you do about what? You are clear as mud. You seem to be whining about a phone not working that you stopped service for. It's doing what it is supposed to do. If you want to reconnect service, call Sprint.

If you have a different question, post it clearly and logically. Think it through before posting.
