As it turns out, I didn’t have to swap the card because there wasn’t one in it to begin with. I simply installed the 64 GB card and was good to go. I thought the phone had a 16 GB card in it out of the box but it does not. The 16 GB is internal memory.
At first I was kind of disappointed but then I realized now my phone was a total 80 GB of storage space. Very cool.
