You'll need to provide a bit more information and context than that if you want assistance from the Community Forum.
What exactly do you mean by "nothing works"?
Is any of the following working?
Connection to the 48 network - i.e. signal bars?
Incoming/outgoing calls?
Incoming/outgoing texts?
Mobile data?
When was everything working ok last?
What changed in the meantime?
If you need to contact 48 support about this then see the links in my signature below.
