Difference between Mobile Ultra and Ultra?

I’d like to know what the difference is between two 64 GB class 10 micro sdxc cards. These are the following two cards:

SKU: SDSDQUA-064G-U46A (The Mobile Ultra card)

SKU: SDSDQU-064G-U46A (The Ultra Card)

I can’t really find any differences between these two cards. Are they the same?

Believe the Ultra is a Class 10 and the Mobile Ultra is Class 6

No difference between both from class or speed the only thing is mobile ultra is with sandisk memory zone and the other not, you can download the app from playstore that’s it i think.

According to it, mobile ultra is older and inferior. I am still confused. Can a Sandisk employee answer?
