Working fine here.
Did anything change on your phone?
Software update or settings changes?
If you do a manual search for networks can you see and connect to 48?
If necessary contact 48 support.
See the link in my signature below.
Hope this helps.
I am not a 48 employee - if you need to contact 48 support then please
click here - if the Chat Now option does not appear on that page then keep trying until it does.
