Some mobile phones have signed up for some services. Is it illegal to send text messages automatically without my consent?

This situation is a menu function made by mobile phone manufacturers, communication companies and SP information service companies in collusion with each other, and such menus are often found on some mentally retarded computers. Fortunately, due to the state's management of information service charges, communication companies will reply to information and ask for reconfirmation before customizing information or downloading files.

If you press these menus, the mobile phone system will think that you want to send such a message code, so it is not illegal. The solution is to fully understand the mobile phone system before buying. If you have already bought it, remember the menus that will send SMS codes to prevent you from pressing them by mistake, and remind others of those menus with your mobile phone.
