Your post was blank @TonyC8407 and the subject line doesn't really clarify the nature of your issue or question.
What exactly do you mean by "no net"?
No network connection at all - i.e. No signal bars?
If that's the case then what happens if you do a manual search for networks?
Can you see and connect to 48?
If not then what happens? Any error messages?
If you do have a connection to the 48 network then what is/isn't working?
Incoming/outgoing calls, incoming/outgoing texts, mobile data?
When was everything working ok for you last?
Did anything change in the meantime?
E.g. phone software update, settings changes, factory reset/restore, new phone handset, returned from roaming abroad, etc.?
If you need to contact 48 support about this then see the links in my signature below.
