Can I repay in advance before the expiration of Unicom's mobile phone number contract?

Of course. Unicom's mobile phone number contract refers to the number's participation in Unicom's preferential activities, such as handling Unicom's prepaid phone bills to send mobile phones, buying mobile phones to send phone bills, saving one and getting three free benefits. According to Unicom official website's inquiry, Unicom's package contract stipulates that it is not allowed to cancel the contract, stop or cancel the account in advance, but it can be repaid in advance. There are still one to three months left in the contract, so you can repay in advance and apply for a new contract.
