Why didn't my contacts transfer to new iPhone

Before going straight to the solutions, you'd better cast a glance at the reasons why didn't contacts transfer to new iPhone. In fact, if you transfer contacts from iPhone to iPhone using iCloud - the Apple built-in backup and transfer program, these acts may lead to a failed transmission:
