T-Mobile Best Buy Upgrade regarding Sim

When I traded in my iPhones for the iPhone 13 the rep kept our sims the same instead of using the ones in the box. My sis came from a XR where I came from a 12.

I believe my sim will support 5G SA but hers probably not. Should I swap to the new sim for both of us now (I’m just gonna do mine just cause lol) to prevent future issues or are we good?
