Shattered screen, need to upgrade to iCloud+ without the device
My iPhone is completely shattered. The bottom half of the screen doesn't work and I am not able to press anything on the screen where it is completely shattered. I haven't been able to use this phone in over a year. However, now I need to get access to my iCloud email and in order to gain access to the email, I have to purchase iCloud+ storage because I used all the storage allowed. Well in order to purchase more storage, when I get to the portion where I select how much GB storage I want to purchase, I am not able to press the confirmation button at the bottom of the screen to move forward with the purchase. I have one other iPhone, that my son uses and is logged into his own iCloud account. Would I be able to log into my icloud account on his iPhone and purchase more storage so I can access my iCloud email? If I am not able to log into my iCloud account via his iPhone, is there any other way to purchase more iCloud storage, other than from the device itself? I don't have the money to buy another iPhone and had to switch back to android, because they are much cheaper. I don't even think the iPhone that I have is even fixable because the screen isn't just cracked, the phone itself is bent. Can someone please help me? I was trying to purchase the extra storage without having to use my son's iPhone since this is supposed to help me gain access to my iCloud email so I can get logged back into our Playstation account because I am locked out of that due to forgotten password and the one thing that my son wants for Christmas is his playstation back. Someone please help me.
