A:AnswerYou can get anything in App Store. If you have a iPhone you can also get messages forwarded to the iPad when on WiFi. Use the iCloud and you can purchase more space for storage. In addition to the 32gb on the device, you get 5 free GB of iCloud space. You can upgrade to 50GB for 99 cent a month.
