Unclear from this thread. I would say if you bring a new internet customer or phone you'd get a referall, but not for "referring yourself"

I agree with John’s answer. You cannot get two referral for the same account

Once you already have a cell plan in place you are not a new customer anymore I'm afraid.

Probably you can invite your wife to sign up

I guess yes if his first fizz account is internet.

cool idea :) yeah
