You'll need to post a bit more information than that if you want assistance from the Community Forum.
What exactly do you mean by "network is not supporting to anything"?
When were things working ok last?
Did anything change since then?
E.g. phone software update, settings changes, factory reset/restore, new phone handset, returned from roaming abroad, etc.?
What exactly is/isn't working?
Connection to the 48 network/signal bars, calls, texts, mobile data?
If you don't have a connection to the 48 network then if you do a manual search for networks can you see and connect to 48?
If you need to contact 48 support about this then see the links in my signature below.
