New photos not showing up in icloud photostream?

I have the iphone 5, ios8. In settings my icloud drive is on and i have cellular data on. Photos are on w/ the my photo stream selected. Why do none of my new photos i take show up on my photostream on my laptop? Am i doing something wrong?

I think if you check, the synchronization through the iCloud occurs when the iPhone is charging, but is off, and is in range of Wi-Fi - you need to check whether cellular data enabled does it - I don't have a good answer so ask some local Apple people or the Apple store near you.
