Can I use a prepaid calling card in combination with a monthly mobile plan? ?

I’m on a mobile plan that only allows for 400 minutes a month. I’m nearly at that limit now only half way through the month and wanted to know if I could buy a calling card, use it with my mobile phone, and not be penalized for the minutes I use.
