My phone is not working on wifi or LTE, not sure why? Thanks

If you haven't already, contact your carrier.

Also, try going to Settings>General>Reset and choose Reset Network Settings.

You'll have to reconnect to your wifi networks.

If neither of those helps, maybe take a look here: https://support.apple.com/en-us/HT201415

So, no apps work at all?

Are you seeing an error?
