What does it mean for China Mobile to send me safe and civilized Internet access?

China Mobile may send you information about safe and civilized Internet access to remind you to pay attention to network security and civilized Internet access, and protect your privacy and data security. This may be a general reminder, not a specific warning to you personally. It is recommended that you be vigilant, avoid revealing personal information on public networks, avoid visiting websites that may carry viruses or malware, and update your security software and operating system regularly to ensure the safety of your equipment.
