You'll need to provide a bit more information than that if you want assistance from the Community Forum.
When was it working ok last?
What changed between then and now?
E.g. software update, settings changes, factory reset, new phone, returned from roaming abroad, etc.?
Do you have a connection to the 48 network?
If not 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.
