how can I transfer my number from fizz to other operatior?

If you would like to port out your number, All you need is your phone number, and your account number. The account number can be found in your account, under my plans --> manage plan.

Just give other provider your number and account number

You account number can found here https://zone.fizz.ca/dce/customer-ui-prod/#/account/plan/... just under your phone number.
