Sync iPhone and iPad

Hi there,

I'll do my best to help but you haven't given us much information to go on. If you are trying to sync all your calendars, contacts, reminders, notes etc.. You can do that in the iCloud settings on both of your devices.

Go to the settings app on either device, click your name at the top, then find iCloud settings. Now turn on all of the switches next to the things you'd like to sync between the devices. You will need to do this on both of your devices.

For more information about syncing each thing see the links below:
