I go to verify it.
I get a link in my phone as SMS.
I open the link.
When I gonna take a photo of my ID card it says "Not enough memory" and I get back to the first step.
Time after time after time after time.
The problem could be in the storage of your phone, it seems that you do not have enough memory to save a photo of your ID. Try deleting some old images or files you don't need, or change the image quality in the camera settings. Although this may not solve the problem, because some users report similar things, so it may be a specific bug.
