Unicom Contract Machine If Party A breaches the contract, will Unicom have a message?

I suggest you carefully read the precautions of Unicom contract machine (customer contact). I suggest you ask the customer service, which number this number belongs to, and whether the official will send a text message to remind you (the user defaults). Friendly reminder: Unicom contract machine (user default) may become a blacklist user of Unicom. If you want to handle Unicom business in the future, you may not be able to handle it normally because of the bad credit of your mobile phone.
