Why does reading text messages also generate traffic?

Mobile phones often receive some text messages, which contain some Internet URLs. If you click on these URLs, the user's phone will connect to the Internet and visit these websites, which will generate traffic (when mobile data is turned on). Customer service 218 will answer your questions. On-demand broadband is as fast as you want. You can apply for it directly by replying the keyword "on-demand broadband" to the China Telecom Guizhou customer service official account, which is convenient and fast.
