Sorry, I never heard about home mobile.
As far as I know, unifi mobile and unifi home. If u refer to unifi home u can check ur bill status through care@unifi app or unifi portal. Both require for u to register.
But if u are referring to unifi mobile postpaid, u can check ur bill status through unifi mobile selfcare portal at mobile.unifi.com.my or can also download unifi mobile care app.
Hope these info may assist u.
