Please I need more space to my phone

It sounds like your phone storage is getting full. There isn't a way to increase this storage space without buying a phone that has more space (i.e. 256GB vs 64GB).

The only thing that can be done at this point is to manage the space you have by deleting things or offloading unused apps.

You can go here to see what is using up your storage:

Settings (gear icon), >General, >iPhone Storage... Let it populate and then you'll have to go from there to decide what you want to do to make room.

I hope that this helps you out. Have a Happy New Year!

If you need more space on your phone, you will need to delete something. You can’t add storage space to any phone.
