When sending a text message, what does it mean if the four digits "1010" are added before the number?

The other party’s smartphone (such as Nokia 6600, 7610) has a software called It is 1010 + mobile phone number. In the same way, if you reply to such a text message, it will also be sent to the gateway of Zhizhong Wanwei. At this time, the information will be considered by Mobile to be not a point-to-point text message, but a "Monternet text message".

You can directly reply to your friend's text message, and there will only be a text message fee of 0.1 yuan, and there will be no information fee. Please note: Do not use English letters or numbers as the beginning of the text message when replying, otherwise the text message service may be customized. This is caused by the limitations of the mobile SMS MISC platform, and there is currently no better solution. Due to limitations of the mobile MISC platform, any uplink information starting with a customization instruction is considered a customization instruction and the corresponding business will be customized. For example, if mp3 matches the customization command "mp" of the film and television park, the business will be customized. If the business is ordered due to misoperation, there will be a customization success message issued from 1862. As long as you reply 00000 to 1010 within 3 days, the business can be presumed and no fees will be charged.
