Did you follow the instructions to successfully activate your SIM?
Do you have a connection to the 48 network - i.e. signal bars?
If not then if you do a manual search for networks can you see and connect to 48?
Are there any error messages on the phone?
Do any services work at all?
Incoming/outgoing calls, incoming/outgoing texts, mobile data?
If you need to contact 48 support about this then see the links in my signature below.
