Your post was blank @45quignalecka so there's not much information to go on in the subject line.
If you want assistance from the Community Forum then you need to explain/describe your issue clearly and in detail.
Do you mean that you don't have a connection to the 48 network - i.e. no signal bars?
If so then when was it working ok last?
What changed in the meantime?
E.g. phone software update, settings changes, factory reset/restore, new phone handset (is it unlocked for use on any network?), returned from roaming abroad, etc.?
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?
Does it make any difference if you reseat your SIM in case it has become dislodged somehow?
If you need to contact 48 support about this then see the links in my signature below.
