You'll need to post a bit more information than that if you want assistance from the Community Forum.
When were things working ok last?
What changed since then?
E.g. phone software update, settings changes, factory reset/restore, new handset, etc.?
What exactly are the symptoms of the problem?
What exactly do you mean by "I don't have network"?
Do you have a connection to the 48 network - i.e. signal bars?
If not then if you do a search for networks can you see and connect to 48?
If you do have a connection then does anything work?
Calls, texts, mobile data?
If you need to contact 48 support about this then see the links in my signature below.
