What does short message service mean?

SMS service is similar to call forwarding. For example, if the other party calls you and you don't receive it, or you are on the phone, or your mobile phone is turned off, then there will be a voice on the phone to remind the other party that you can't come to the phone now, and a text message will inform you to call back later. After that, you will receive a short message on your mobile phone, reminding you who called you and when.

Short message forwarding service is a short message forwarding function, which provides customers with voice-like call forwarding. Customers can use this service as long as they apply to open the SMS forwarding function and set the forwarding number as required. After setting SMS forwarding, the mobile phone will no longer receive peer-to-peer SMS messages from other mobile phone numbers, but directly forward them to the mobile phone calling the target number.

There are generally four reasons for prompting the other party to open SMS calling service when calling:

1, turn it off.

2. There is no signal from the other party outside the service coverage area.

3. Set the flight mode.

4. You are blacklisted. In this case, once you dial the phone, you will be prompted to open the SMS service.

SMS calling service is a service (name) provided by mobile company, and the cost is 1 yuan/month.

When the other party shuts down and can't get through, you will tell the other party to start the SMS calling service. When he opens his mobile phone, he will receive your call record: XXXXXXXXXXX users call you at XXXXXXXXX time, please reply in time.

If the incoming call is blacked out, it will prompt the caller that "the other party has turned off", "the other party has turned off" and "the number you dialed does not exist", and will also call the SMS service.
