What do you mean?
What else do you think you do with a SIM card?
Maybe if you explained your issue or question more clearly and in more detail it would be easier for those on the Community Forum to offer advice?
What exactly are you trying to do, what steps are you taking to do it, does something go wrong, any error messages, is there something in particular that is causing you confusion?
Maybe the New to 48 FAQs might address any confusion that you have?
If you need to contact 48 support about this then see the links in my signature below.
