Your post is basically blank @Jamiec6609 so it's difficult to offer and specific advice.
If you want assistance from the Community Forum then you need to describe your issue/problem clearly.
What are you trying to do, what steps are your taking to do it, what happens/guess wrong, any error messages, etc.?
Did you successfully activate the SIM?
Is your phone unlocked for use on any network?
Are there any error messages on the phone?
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?
If not then what happens? Any error messages?
If you do have a connection to the 48 network then do any services work?
Incoming/outgoing calls, incoming/outgoing texts, mobile data?
If not then what happens when you try to use them? Any error messages?
If you need to contact 48 support about this then see the links in my signature below.
