Payment done still not upgraded my iCloud storage

Hello Navneet_1990,

Thanks for choosing the Apple Support Communities. We see you paid for iCloud+ but you are not seeing the storage increase reflected on your device. We have a few things that will help you resolve this.

1. ensure you are signed in using the Apple ID you made the iCloud+ purchase on: Sign in to iCloud on all your devices - Apple Support
2. Make sure you have followed all of the steps outlined here: Upgrade to iCloud+ - Apple Support
3. Restart your iPhone and check your storage again: Restart your iPhone - Apple Support
4. We also suggest trying on cell data, and on Wi-Fi to see if the change is reflected.
5. If issues persist, please reach out to Apple Support: Get Support

We hope this helps.

Cheers!
