Can I activate 2 referral code one for home internet and one for cellular
One can use a referral code only when activating the first plan of any Fizz account.
So if you plan to have separate Fizz accounts for each plan, you can use a referral code each time.
However if you want to activate home internet and a mobile plan on the same account, you can use a referral code only once.

*Note that each Fizz account requires an unique email address. Also points/upgrade bonuses cannot be shared between accounts.
No one code per account and not one code per plan :)
No only one code :)
