How to turn on the number change reminder

If you need to open a number change notice, the number change notice is also called a number change reminder service. After you open this service, others call your old and new numbers, and the system will automatically send you a text message to inform you to change the number (the number received by the other party is your new mobile phone number). Send a text message to the same calling number only once. Call the old number to the new number, so as to send a short message to the user who dialed the old number, and the incoming call will be answered by the new number. You can edit the short messages "HHTZ", "KTHHTZ", "number change notice" and "number change notice" to10010; Or edit the short message "xy" to 106558 129 to apply for opening. Function fee: 5 yuan/month. Only when the old number is set to "unconditional call forwarding" to the new number can the user who dialed the old number be sent a number change notification SMS.
