You can use iCloud from anywhere by signing in to iCloud.com using a web browser recommended in the Apple Support article System requirements for iCloud.
For a list of apps and features available on a tablet, see What is iCloud.com?
Sign in to iCloud.com
Go to iCloud.com, then sign in to your Apple Account with an email address or phone number and your password.

If you do not see the apps or data you are looking for
Depending on the device and account you use to sign in to iCloud.com, you have access to different apps and features. If you do not see what you are looking for, see if any of the following are true:
You signed in on a different device: if you sign in to iCloud on a computer or a phone, you have access to a different set of apps and features than if you sign in using a tablet.
You signed in using a different Apple Account: If you have more than one Apple Account, make sure to sign in to iCloud.com with the account that has the data you are looking for. See Get more iCloud features.
