Why do mobile phones receive regular traffic alerts from 1000 1 every day? Is there a charge?

If the mobile phone receives 1000 1 SMS reminders at the same time every day, the initial judgment is that the mobile phone terminal initiated it automatically. Please check whether the mobile phone has downloaded the third-party monitoring software and set the software to off. Just to remind you, sending and receiving messages to 1000 1 is free. Broadband on demand, fast thinking. The official account of China Telecom's Guizhou customer service WeChat can directly handle the keyword "Broadband on demand", which is convenient and fast. Customer service 34 will answer your questions.
