Telecom suddenly sent a short message to the answering machine because the traffic was not used within 7 days after activation and the phone was changed. According to the relevant public information, it should be that traffic and telephone communication have not been used within 7 days after activation. The normal process of card opening set by big data system is that the card must make a phone call and surf the Internet within 7 days after card opening, otherwise it will be judged as useless and the call function will be turned off directly. First of all, our telecom card and mobile phone card need real-name confirmation, so you should confirm your real-name information when logging in.
