I opened the SMS forwarding function. How to use it?

Hello, usage: 1, only point-to-point SMS can be transferred, and non-point SMS cannot be transferred. 2. The SMS received by the call forwarding number shows the sender's number. 3. SMS call forwarding cannot be set twice, and only one call forwarding can be supported. 4. In order to avoid circulation, when SMS call forwarding is turned on, set SMS call forwarding to mobile phone B. If user B sends you a message, SMS housekeeper will not forward SMS call to number B..5. When users have both SMS housekeeper and SMS message forwarding services, they can use SMS housekeeper service and SMS call forwarding service at the same time. As long as the SMS butler service is opened, the SMS butler can receive messages sent directly to himself or messages forwarded by incoming calls. 6. When the user opens SMS, emoticon message or emoticon multimedia message at the same time, you can receive emoticon multimedia message by calling forward number, but you can't receive emoticon multimedia message (the received message is still normal). Emoji MMS and Emoji SMS are mutually exclusive and cannot be used at the same time. Other services can be used simultaneously. (The above content is only applicable to Guangdong Unicom users)
