Hi TampaLin,
Thank you for participating in the Apple Support Communities.
Instead of using iTunes to sync data, you can sync many types of data (such as contacts, calendars, pictures, reminders) using iCloud.
See this link for more information and the steps to set up iCloud:
Apple - iCloud - Learn how to set up iCloud on all your devices.
iTunes is required to sync media such as music, tv shows, or video between iOS devices; but you can download your iTunes Store purchases directly to your iOS device(s) using the steps found here:
Download past purchases - Apple Support
All the best,
Jeremy
