Unicom has been down for half a year, and it can still receive text messages.

After the numbers of China Unicom and China Telecom are down, you can still receive official short messages, no doubt. If you want to recycle the number, the system will automatically destroy all the information of the mobile phone. And it will take more than three months to continue selling.

It is impossible for others to change your QQ number, because he doesn't know your QQ number at all, and only knows the first and second digits at most.

In terms of binding, it is very simple to unbind by verifying the mailbox and secret protection, and you can also change the binding of mobile phone number.

Don't worry too much, not so many people are keen on QQ, and not only one person has this situation. Unicom is not a fool, and will not let you stop for free forever.
