iPhone 6
How can I know how many gigs my iphone has without turning it on?
With the information on the back of the device, can I have this data?

Hello,
If you are asking how much local storage the phone is using, the answer if no. You would have to turn it on for that:
How to check the storage on your iPhone, iPad, and iPod touch
If you are asking about iCloud storage, you could use another device and go to iCloud.com and log in with your Apple ID and password.
Good luck.
