How to send text messages to others with the cancelled mobile phone number?

You can't send messages after the phone is logged off.

You can't send other messages unless you re-register this number.

After the mobile phone number is cancelled, the operator will freeze the number for three months and then put it back in the selected number pool. During these three months, you can take your friends to the local business hall to apply for a number, which belongs to an old user, and then transfer it to you. If the number is auspicious, it will not be refunded after the freezing period.
