Be sure you backup your new iPad or you could be screwed like me. I setup my new iPad and entered a 6 digit numeric code and the Touch ID. Then iCloud and all apps etc and all was working fine, unlocking with the Touch ID. Then I went to AT&T to get a SIM and had to restart the device. It then asked me for an alphabetical passcode, not the 6 digit code. Won't take the numbers and keeps locking me out. I only use one code with my devices, so I know I am not entering the wrong code. Apple says the only way around it is to wipe the device and start over. Sucks!
