You'll need to provide a bit more information than that if you want assistance from the Community Forum.
Did you successfully activate your SIM?
Is your phone unlocked for use on any network?
What happens when you install the SIM in your phone?
Any error messages?
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, what happens? Any error messages?
If you do have a connection to the 48 network then what happens when you try to make a call or send a text?
Any error messages?
If you need to contact 48 support about this then see the links in my signature below.
