Specific provinces, according to different terminals, different contract time, subsidies will be different, you can contact local customer service for details.

when handling a contract machine, you need to bind a contract number with the mobile phone terminal and sign a contract at the same time. During the contract period stipulated in the contract terms, you need to bind the contract number with the mobile phone terminal according to the contents agreed in the contract, that is, if the machine and card are not used separately, you can enjoy the subsidy discount according to the contents agreed in the contract. If you violate the contents of the contract, you will not be able to enjoy the subsidy and bear the liability for breach of contract.
