When was everything working ok last?
Did anything change in the meantime?
What exactly do you mean by "no mobile network"?
No connection to the 48 network - i.e. no signal bars?
If so then if you do a manual search for networks can you see and connect to 48?
Is anything working? Calls, texts, mobile data?
Do you have an active membership plan?
If you need to contact 48 support about this then see the links in my signature below.
