I have purchased storage on iCloud but still not updated on phone

Hello sandipumap96,

Thank you for using Apple Support Communities. You've reached out to the right place for help. If you increased your iCloud storage but it's not reflecting correctly on your iPhone, we'd like to help out and troubleshoot this issue. First, let's double check and review your active iCloud+ plan. Just to make sure that this plan to iCloud+ was properly set up:

1.) Navigate to Settings.

2.) Tap on your name.

3.) Tap on iCloud and then tap on Manage Your Plan.

In this section, you should see your iCloud+ plan listed. If incorrect information is showing, you might need to properly sign up for iCloud+ plan again. If the correct plan is displaying, then try the following steps here:

1.) Restart your iPhone to help refresh things: Restart your iPhone - Apple Support

2.) Make sure that all updates have been installed. This can help fix unique issues.

This can usually help with unique issues, since updates include fixes. Just in case, this link can guide you through the update process: Update your iPhone or iPad - Apple Support

1.)Back up your device using iCloud or your computer.

2.)Plug your device into power and connect to the internet with Wi-Fi.

3.)Go to Settings > General, then tap Software Update.

4.) If you see more than one software update option available, choose the one that you want to install.

5.) Tap Install Now. If you see Download and Install instead, tap it to download the update, enter your passcode, then tap Install Now. If you don't know your passcode, learn what to do: If you forgot your iPhone passcode - Apple Support

We hope this helps out. Thank you for using Apple Support Communities. Take care.
