Can't increase cloud storage with out using iphone
daughters iphone 11 screen is unresponsive, in order to get it fixed I need to disconnect her account from the phone. Problem is, I need to back it up 1st & her cloud storage is full. I have tried to purchase more storage by signing in to icloud on my laptop but in order to complete, it is sending something to her device, which I can't use because the screen isn't working... I am going around in circles with it. There is no option to not use the device to confirm, can I call apple to sort this over the phone? I have tried to search but I am not having any luck...
Any help would be really appreciated! Thanks.
iPhone 11, iOS 18
