Your post is a bit unclear.
Do you mean that you ordered a SIM but it hasn't arrived yet?
If that's the case then you should contact 48 support and ask them what the status of your order is.
See the links in my signature below.
If that's not the problem then please clarify what it actually is.
What exactly you're trying to do, the exact steps that you take, what goes wrong, any error messages etc.
