Chosen Solution

Something like Android SSD cards, or What hardware to I need to exchange to increase the internal memory? What is the name? What is the average price?

You’ll need BGA chip rework skills and special hardware/software tools to edit low-level data of the flash memory chip so the phone can accept the new chip. It’s not as easy as an SD card swap for Android phones.

Unfortunately, there are no Apple products designed to have expandable memory. What you can do is connect your phone to the iCloud for extra space and automatic back up. Depending on how much space you need, you can purchase extra. No matter what, it is safer to use this option in case your phone ever calls it quits. You then at that point can use iTunes to download whatever you backed up.

Hey Royer Adames, Sadly, you can’t increase your memory.
