Not sure what exactly you mean but, in case it's relevant, 48 (unlike some other providers) don't support group/family accounts allowing more than one SIM/phone number/membership to be managed under a single login.
Every SIM/phone number needs its own login and associated email address.
So your husband will need to create an account using his own email address, order a SIM, and get set up the same way that you did originally.
If you need to contact 48 support about this then see the links in my signature below.
By the way, it's not a great idea to post personal details such as your husband's name and phone number in a public forum like this where anybody can see and use them.
You might want to edit your post to remove these details.
