I need to add storage space to my Ipad. I tried to do it from ipad. I put in all the information it asked for but nothing happened. Ipad is running real slow.
You will have to delete unnecessary apps, photos, music, etc. or upload them to a cloud service, external hard drive or a computer. You cannot add physical storage to your iPad.
Update: If you're referring to additional iCloud storage, check out the information found via the following link.
