Taobao 14 contract version means a bare phone that has signed a contract with an operator.

Purchasing the Apple contract-free version does not include discounts or phone bills, and the buyer needs to choose a communication operator and freely choose a package that suits him or her. The advantage of Apple's contract-free version is freedom and convenience. Users can use and change the mobile phone cards of the three major operators at will, and can also achieve global roaming, which greatly improves the convenience of traveling and business trips abroad, without the trouble of changing phones because of changing operators like a long time ago.
