How to see how many minutes I use on my phone? EE iPhone 5s?

I texted 130 and called it but it only tells me my data that is left -.- I want to know how many minutes my phone has used since I got it which may be unlimited but I'm getting a new sim with unlimited data and limited minutes and I want to make sure I'll have enough minutes
