Im trying to upgrade to more storage from my phone and nothing is working

You can't add storage to your iPhone and iCloud storage adds nothing to your iPhone in the way of storage. You can go to Settings > General > iPhone Storage and see if there are any recommendations to save space on your iPhone.

What's the difference between device storage and iCloud storage? - Apple Support

What to do:

Clear Space:

Try clearing internal storage though use of the following:

What Space to Clear:

A. Clear Temporary Internet Files:

Clear your Temporary Internet Files(Cookies & Cache) of Safari:

• Cookies perform remembrance of certain site-entered data.
• Cache keeps a snapshot of the last time you visited a site.
• Go Here: Clear the History and Cookies from Safari on your iPhone, iPad, or iPod Touch - Apple Support

And...



B. Clean TV and Music Libraries:

Remove all unneeded files from your TV and Music Libraries. Full-Movies take up 2-4GB typically, and a bunch of those would take up a load of storage, ideally. So, if you have any movies that are not needed, then delete them.

And...

C. "Other" being the Culprit:

Use this Link: How to Check the Storage on your iPhone, iPad, and iPod touch - Apple Support. The storage named "Other" is the grey bar. So, to clear that, refer to my User Tip: How to Clear "Other" in your iPhone's Storage - Use Backup - User Tip

What do you mean "trying to upgrade more storage" - you cannot add storage to your iPhone, do you mean you're trying to add more storage to your iCloud Subscription?
