Phone/smartchip question

So, my phone turned itself off today for some reason. I don’t know why, but when I turned it back on it said “smartchip registration failed” I tried reinstalling the chip but to no avail. On top of all that, I’m getting ZERO signal too. Any clues on what’s going on?

It locked out your sim card.

Okay cool, anyway I can fix this?

You gotta take it to a service provider or store. Like any store that sells phones/plans or the official carrier store.
