Icloud

And the screenshot you posted above shows that you are renting the highest possible plan. Renting iCloud storage does not add storage space to an iPhone.

Yes, I understand that, and your previous screenshot clearly shows that you have the 2TB option. However, that does not, and it will not add space to your phone.

Thank you for the screenshot.

You are utilizing less than 10% of your rented cloud storage space. Perhaps you could use a smaller, less expensive plan?

You can not add storage space to an iPhone.
