What exactly do you mean by "business family"?
If you mean an account with another provider that covers multiple users/SIMs/numbers then I don't think that this will work.
I think that you'll have to transfer each account/number over individually.
48 doesn't provide accounts that cover multiple numbers/SIMs and each user needs their own separate account.
You may need to contact 48 support about this.
