I have read a lot of review questions that mention what size SD card is best for the ultra. So I bought the 2020. IT DOES NOT COME WITH AN SD CARD SLOT!! I am considering returning it to Amazon and trying to get an Ultra that has an SD card slot. I have read all of the posts about insufficient memory, I am hoping that an SD card would fix this issue.
There isn't a current model that comes with an SD slot, so you'd have to go used. Technically it shouldn't be necessary, but as you've seen many people would state otherwise. The newer models tend to come with more storage, so it does make it less of an issue.
Edit: The Ultra LT available at Walmart still has a microSD slot, but it's a generation behind the 2020 Ultra.
