Fizz allow the use of the SIM for 3 months outside the coverage area
The majority of your usage (calls, texts and data) must be done on the Fizz network.
We reserve the right to interrupt or block access to our network of partner providers if you use your mobile service primarily on their networks for 3 consecutive payment periods.
You can contact the support to see if buying addons they will allow more then 3 months
or buy a second sim :D
